Which mechanism requires energy input by the cell in the form of ATP hydrolysis ABC None of the mechanisms require energy input?

Which mechanism requires energy input by the cell in the form of ATP hydrolysis? none of the mechanisms require energy input: All three mechanisms are forms of diffusion. Transport by diffusion of a molecule down its concentration gradient is a spontaneous process that requires no energy input.

What does the nuclear envelope do in the endomembrane system?

The endomembrane system includes the nuclear envelope, lysosomes, vesicles, the ER, and Golgi apparatus, as well as the plasma membrane. These cellular components work together to modify, package, tag, and transport proteins and lipids that form the membranes.

How are molecules transported across the cell membrane?

Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes.

What organelle is indicated by the letter c what cellular process occurs here?

The event indicated by C includes the fusion of a secretory vesicle with the plasma membrane and the subsequent release of the vesicle contents to the extracellular space. Structure D is a lysosome, which stores enzymes that catalyze the hydrolysis (digestion) of organic cellular materials.

Which organelle is responsible for processing and packaging proteins?

Golgi Body

A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.

Which transport process is the main mechanism for the movement of most macromolecules by body cells?

Which transport process is the main mechanism for the movement of most macromolecules by body cells? Receptor-mediated endocytosis.

What type of functions does the presence of microvilli typically indicate?

What type of cell functions does the presence of microvilli typically indicate? increase surface area for absorption.

What process allows for the production of molecule B from a template consisting of molecule A?

What process allows for the production of molecule B from a template consisting of molecule A? Transcription is the synthesis of RNA using DNA as a template.

What process ultimately pinches a dividing cell?

Cytokinesis is the physical process that finally splits the parent cell into two identical daughter cells. During cytokinesis, the cell membrane pinches in at the cell equator, forming a cleft called the cleavage furrow.

Which process requires the energy provided by ATP?

Active transport
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).

Which of the following processes requires ATP?

ATP is consumed for energy in processes including ion transport, muscle contraction, nerve impulse propagation, substrate phosphorylation, and chemical synthesis.

Which mechanism requires energy input by the cell?

Active transport: moving against a gradient

To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells.

What is a nuclear membrane function?

A nuclear membrane is a double membrane that encloses the cell nucleus. It serves to separate the chromosomes from the rest of the cell. The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials, such as nucleic acids and proteins, between the nucleus and cytoplasm.

Is nuclear envelope part of the endomembrane system?

The endomembrane system includes: the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and the plasma membrane.

What is the process by which proteins are made and then exported from the cell?

Protein synthesis, also called translation , begins when the two ribosomal subunits link onto the mRNA. This step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer RNAs (tRNAs).

What are 4 methods of transport across the membrane?

Basic types of membrane transport, simple passive diffusion, facilitated diffusion (by channels and carriers), and active transport.

How do molecules go in and out in the cell?

In facilitated diffusion, substances move into or out of cells down their concentration gradient through protein channels in the cell membrane. Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient.

What is a facilitated transport?

Facilitated transport is one way of moving those materials without expending cellular energy. In facilitated transport, materials are moving down a concentration gradient. In other words, they are moving from an area of high concentration to low concentration, as in passive diffusion.

What is Golgi apparatus function?

The Golgi apparatus transports and modifies proteins in eukaryotic cells. … The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell. Typically textbooks illustrate the Golgi as something resembling a stack of pita bread.

What is a ribosomes function?

A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.

Is nucleus an organelle?

​Nucleus. A nucleus is a membrane-bound organelle that contains the cell’s chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus.

What is responsible for the processing and packaging in cell?

Golgi apparatus is the organelle responsible for processing and packaging proteins and lipids made by the cell.

Which organelle is responsible for cellular respiration?

mitochondria
Encyclopædia Britannica, Inc. The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).

What are lysosomes responsible for?

Lysosomes are membrane-bound organelles with roles in processes involved in degrading and recycling cellular waste, cellular signalling and energy metabolism. Defects in genes encoding lysosomal proteins cause lysosomal storage disorders, in which enzyme replacement therapy has proved successful.

What substances are moved by active transport?

In active transport, substances (e.g. ions, glucose, and amino acids) move across a membrane from a region of their lower concentration to a region of their higher concentration. Thus, they move against the direction of their concentration gradient.

What is the name of the process during which the plasma membrane surrounds and envelopes smaller cells solid particles or liquids multiple choice question?

[1: During endocytosis, a segment of the plasma membrane pinches off to form a vacuole or a vesicle inside the cell. 2: Phagocytosis, pinocytosis, receptor-mediated endocytosis are 3 different types of endocytosis.

What does passive membrane transport processes include?

Three common types of passive transport include simple diffusion, osmosis, and facilitated diffusion. Simple Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. A couple of common examples will help to illustrate this concept.

What major function occurs on the specific membranes indicated by a?

What major function occurs on the specific membranes indicated by A? Structure A is the rough endoplasmic reticulum (ER). The figure illustrates how proteins are synthesized on ribosomes bound to the rough ER, sorted in the Golgi, and delivered to the plasma membrane for secretion or packaged into lysosomes.

What is the importance of microvilli to the digestive process?

Microvilli on the surface of epithelial cells such as those lining the intestine increase the cell’s surface area and thus facilitate the absorption of ingested food and water molecules.

What is engulfment processes that require ATP?

Exocytosis. Engulfment processes that require ATP; Used to eject wastes and to secrete cell products. Phagocytosis.
