Why is life based on carbon based molecules quizlet?

Why? The building block of life. Because carbon atoms are the basic of most molecules that make up living things. … Carbon atoms can form covalent bonds with up to four other atoms (including other carbon atoms) because each carbon atom has 4 unpaired electrons in outer energy level.

What does carbon-based life form mean?

Originally Answered: What is a carbon-based lifeform? All life on Earth, at least that we know of so far, is carbon based. Basically it means that carbon atoms form the scaffolding for hydrogen, oxygen and nitrogen to form the complex molecules that our bodies are based on.

Does carbon make up every living thing?

Carbon is found in all living things. Carbon atoms move constantly through living organisms, the oceans, the atmosphere, and the Earth’s crust in what is known as the carbon cycle. The directions taken by carbon atoms through this cycle are very complicated and can take millions of years to make a full circle.

Why life is carbon based?

Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.

What is carbon and why it is important to life?

Carbon is an essential element for all life forms on Earth. Whether these life forms take in carbon to help manufacture food or release carbon as part of respiration, the intake and output of carbon is a component of all plant and animal life. Carbon is in a constant state of movement from place to place.

Why is carbon considered a unique element of life?

Carbon atoms are unique because they can bond together to form very long, durable chains that can have branches or rings of various sizes and often contain thousands of carbon atoms. … Carbon atoms also bond strongly to other elements, such as hydrogen, oxygen, and nitrogen, and can be arranged in many different ways.

What makes carbon so useful for building compounds in living things quizlet?

Carbon can bond to four other atoms which makes it so there is a wide variety of molecules that it can make. Carbon has the most potential to make large, complex and varied molecules. It can make proteins, DNA, carbohydrates and other molecules that distinguish living matter from inanimate material.

What would most likely happen to life on Earth if the carbon cycle stopped?

What would most likely happen to life on Earth if the carbon cycle stopped? Life would cease to exist. … Carbon-based macromolecules are found in all life forms.

Which macromolecule provides a person with most of the energy that is needed for daily activities?

Which macromolecule provides a person with most of the energy that is needed for daily activities? Glycogen is an energy-storage molecule in humans.

What is the primary function of the carbon cycle quizlet?

The carbon cycle is one of the main cycles in nature, the carbon cycle produces nutrients and energy in plants for animal consumption. The cycle also is responsible for all oxygen production.

Why are hydrocarbons excellent fuels?

Hydrocarbons are organic molecules consisting entirely of carbon and hydrogen. … They make good fuels because their covalent bonds store a large amount of energy, which is released when the molecules are burned (i.e., when they react with oxygen to form carbon dioxide and water).

What is meant by the statement saturated hydrocarbons are relatively inert?

What is meant by the statement, “Saturated hydrocarbons are relatively inert”? They are difficult to obtain energy from. They will not form other compounds readily.

Which formula tells us the most about a molecule?

Which formula tells us the most about a molecule? The structural formula tells us more than either the molecular formula or empirical formula, because a structural formula contains the information from a molecular and empirical formula in addition to showing the connections of atoms in the molecule.

Why hydrocarbons are important in our daily life?

Hydrocarbons are the principal constituents of petroleum and natural gas. They serve as fuels and lubricants as well as raw materials for the production of plastics, fibres, rubbers, solvents, explosives, and industrial chemicals.

Why are hydrocarbons important in living organisms explain?

Hydrocarbons are organic molecules consisting entirely of carbon and hydrogen. … They make good fuels because their covalent bonds store a large amount of energy, which is released when the molecules are burned (i.e., when they react with oxygen to form carbon dioxide and water).

What kind of carbon carbon bonds are found in alkane molecules?

Alkanes. Alkanes, or saturated hydrocarbons, contain only single covalent bonds between carbon atoms. Each of the carbon atoms in an alkane has sp3 hybrid orbitals and is bonded to four other atoms, each of which is either carbon or hydrogen.

Which of the following statements best describes how molecules released by the fish?

Which of the following statements best describes how molecules released by the fish become nutrients for the plants? The ammonia molecules released by the fish are converted by the bacteria to nitrates, which are used by the plants to make proteins and nucleic acids.

Why do hydrogen bonds form between water molecules?

Water hydrogen bonds

In liquid water, all water molecules have at least one hydrogen bond to neighboring water molecules with effectively no free water molecules under ambient conditions (i.e. molecules with no hydrogen bonds).

What are the results of hydrogen bonding?

Hydrogen Bonding. Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.

Why are carbon based molecules the foundation or building blocks of life?

Cells are made of many complex molecules called macromolecules, which include proteins, nucleic acids (RNA and DNA), carbohydrates, and lipids. The macromolecules are a subset of organic molecules (any carbon-containing liquid, solid, or gas) that are especially important for life.
