What Can We Infer If We See A Large Number Of Mitochondria In A Cell?

If we see a large number of mitochondria in a cell, we can infer that the cell has a great metabolic demand. A high metabolic demand means that the cell requires a large amount of energy released in the process called cellular respiration. The mitochondria are where most of the energy of the cell is made.Jul 19, 2021

What does the presence of many mitochondria in a cell suggest?

What does the presence of many mitochondria imply about a cell’s energy requirements? Mitochondria produce energy, in the form of ATP molecules, for the cell. A large number of mitochondria in a cell indicates a high demand for energy.

What cell has a large number of mitochondria in a cell?

muscle cells
For example, liver cells and muscle cells contain a lot of mitochondria. Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells.

Which type of cell is most likely to have the largest number of mitochondria?

It’s commonly believed that it’s muscle cells that have the largest amount of mitochondria, and for good reason. Muscle cells are continually used to move the body, so they have the most mitochondria because of the large energy requirement.

Which cells have the most mitochondria?

each mitochondrion contains 17,000 tiny assembly lines for making ATP (energy) mitochondria are responsible for creating more than 90% of the energy needed to sustain life and support organ function. heart muscle cells contain about 5,000 mitochondria per cell.

How many mitochondria are in a cell?

Just as the chloroplasts in plants act as sugar factories for the supply of ordered molecules to the plant, the mitochondria in animals and plants act to produce the ordered ATP molecules as the energy supply for the processes of life. A typical animal cell will have on the order of 1000 to 2000 mitochondria.

Why do muscle cells have a large number of mitochondria?

This is because mitochondria produce ATP during aerobic respiration and ATP is needed for muscle to contract. … Muscles cells contain more mitochondria because they have to release large amount of energy quickly for movement.

Which organelle will be found in large number in cells that need a lot of energy?

mitochondria
For instance, cells that use a lot of energy tend to contain large numbers of mitochondria (the organelle responsible for harvesting energy from food).

Why do larger cells need more mitochondria?

Why do large cells need more mitochondria? Need more energy. Mitochondria is place for cellular respiration. More mitochondria = more ATP produced.

Which of the following features is most likely to limit the maximum size of a cell?

Cell size is limited by a cell’s surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell.

Why do egg cells have a large amount of mitochondria?

During fertilization, only the sperm’s head containing its DNA will penetrate the egg and the two nuclei fuse. … The sperm’s midpiece contains many mitochondria so that a supply of energy is available for the sperm to perform its function of traveling to and later fertilizing the egg.

Which of the following is are likely to limit the maximum size of a cell?

Exam 2 Flashcards
Question Answer
Which of the following structures is found in eukaryotic but not prokaryotic cells? mitochondria
Which of the following is/are likely to limit the maximum size of a cell? the shape of the cell, the time it takes a molecule to diffuse across a cell, and the cell’s surface-to-volume ratio

How big is a mitochondria?

0.5 to 3 µm
Nearly all living eukaryotic cells contain mitochondria, however their size (~ 0.5 to 3 µm), shape and number varies considerably, both between different cell types but also within the chondriome (the total mitochondria population of a cell)12,13.

What determines the number of mitochondria in a given cell type?

The number of mitochondria present in a cell depends upon the metabolic requirements of that cell, and may range from a single large mitochondrion to thousands of the organelles. … Together, the various compartments of a mitochondrion are able to work in harmony to generate ATP in a complex multi-step process.

Which cell has the least number of mitochondria?

The number of mitochondria per cell varies widely—for example, in humans, erythrocytes (red blood cells) do not contain any mitochondria, whereas liver cells and muscle cells may contain hundreds or even thousands. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species.

How much mitochondria is in a skeletal muscle cell?

Indeed, the present evaluation reveals that smooth muscle mitochondrial content, as assessed by CS activity, is only ∼42% and ∼22% that of skeletal and cardiac muscles, respectively.

How many mitochondria are in a eukaryotic cell?

Like many unicellular eukaryotes, which can have as few as a single mitochondrion or a few dozen mitochondria per-cell (Gray et al., 2004) and can also have on the order of 105 mitochondria (Okie et al., 2016), multicellular eukaryotes tend to have a wide range of per-cell mitochondria numbers with estimates in …

What does mitochondria do in muscle cells?

To meet this energy demand, muscle cells contain mitochondria. These organelles, commonly referred to as the cell’s “power plants,” convert nutrients into the molecule ATP, which stores energy.

Why mitochondria is a cell within a cell?

Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. … It is for this reason that mitochondria are often referred to as the powerhouses of the cell. Cells that need a lot of energy, like muscle cells, can contain thousands of mitochondria.

How many mitochondria are in a sperm cell?

The typical mammalian sperm midpiece contains approximately 50–75 mitochondria with one copy of mtDNA in each.

Where can we find a greater number of mitochondria in a leg muscle or in a skin cell?

There are more mitochondria in muscle cells than there are in skin cells. Cellular respiration occurs in mitochondria. There are three stages to cellular respiration- Glycolysis, the Krebs cycle, and the electron transport chain (ETC).

Why does liver and muscle cells have large number of mitochondria?

Since liver cells are highly regenerative and muscle cells spend high energy in contraction and expansion, these cells require high energy. Hence, presence of large number of mitochondria in liver cells and muscle cells is justified.

What does exercise do to the number of mitochondria in our muscle cells?

Mitochondria transform energy from food into cellular energy. Exercise increases the number of mitochondria improving your body’s ability to produce energy. In other words, the more mitochondria you have, the more energy you can generate during exercise and the faster and longer you can exercise.

Which organelles would be present in large numbers in cells that manufacture proteins?

Ribosomes. Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell’s cytoplasm or embedded within the endoplasmic reticulum.

Which organelle would be found in large quantities in muscle cells?

mitochondria
Numerous mitochondria are found in each muscle cell to provide metabolic energy for muscle contraction.

Which is larger and more complex prokaryotic or eukaryotic cells?

Eukaryotic cells are generally larger and more complex than prokaryotic cells. They also contain a variety of cellular bodies called organelles. The organelles function in the activities of the cell and are compartments for localizing metabolic function.

How do mitochondria increase in size?

These proteins that are necessary for the metabolic reactions in the mitochondria seem to be increased when the body undergoes aerobic exercise. The overall density of mitochondria in muscle tissue increases in response to aerobic workouts. More mitochondria means greater use of oxygen to produce more ATP and energy.

How do some cells have more mitochondria?

Logically, mitochondria multiply when a the energy needs of a cell increase. Therefore, power-hungry cells have more mitochondria than cells with lower energy needs. For example, repeatedly stimulating a muscle cell will spur the production of more mitochondria in that cell, to keep up with energy demand.

Can a cell have more than one mitochondria?

Mitochondria are found in all body cells, with the exception of a few. There are usually multiple mitochondria found in one cell, depending upon the function of that type of cell. Mitochondria are located in the cytoplasm of cells along with other organelles of the cell.

What would happen if a cell was larger?

If the cell grows too large, the plasma membrane will not have sufficient surface area to support the rate of diffusion required for the increased volume. In other words, as a cell grows, it becomes less efficient.

What factors limit cell size?

The factors limiting the size of cells include: Surface area to volume ratio (surface area / volume) Nucleo-cytoplasmic ratio. Fragility of cell membrane. The reason that the cell can grow to a certain limit is its surface area to volume ratio.

Which cell has a larger surface area?

Smaller cells have a much greater surface area to volume ratio allowing material to diffuse throughout the entire volume of the cell quickly and efficiently.

How many mitochondria are in an egg?

Each mitochondrion in a cell can have multiple copies of the mtDNA genome. In humans, the mature egg cell, or oocyte, contains the highest number of mitochondria among human cells, ranging from 100,000 to 600,000 mitochondria per cell, but each mitochondrion contains only one copy of mtDNA.
