Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. They can even join “head-to-tail” to make rings of carbon atoms.

Why is carbon present in so many types of molecules quizlet?

Why is carbon so present in so many types of molecules? It can form up to four covalent bonds. The diagram that shows the pattern for the carbon atom has four valence electrons orbiting the nucleus on a ring.

Which answer best explains why carbon is an important molecule to the existence of life?

Correct answer:

Explanation: Carbon is phenomenally important to life as we understand it. The ability to form bonds with up to four different atoms gives carbon an incredible chemical diversity, and allows for carbon to make long chains and aromatic compounds.

Which sentence best describes the role carbon plays in the structure of compounds present in living things?

Which sentence best describes the role carbon plays in the structure of compounds present in living things? Carbon plays a fundamental role in the structure of organic compounds.

Which statement best explains why carbon is present in so many kinds of molecules it can form four covalent bonds?

Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

Why is carbon so common in making molecular backbones?

The bonding properties of carbon

For one thing, carbon-carbon bonds are unusually strong, so carbon can form a stable, sturdy backbone for a large molecule. Because a C atom can form covalent bonds to as many as four other atoms, it’s well suited to form the basic skeleton, or “backbone,” of a macromolecule.

Which characteristic best explains why carbon is the backbone of all organic molecules in living things?

The properties of carbon make it the backbone of the organic molecules which form living matter. Carbon is a such a versatile element because it can form four covalent bonds. Carbon skeletons can vary in length, branching, and ring structure.

What are carbon atoms?

Carbon atoms comprise a nucleus of neutrons and six protons surrounded by six electrons. Quantum mechanics dictates that the first two electrons occupy the inner atomic orbital, while the remaining four electrons have wavefunctions that only half-fill the second standard and three second principal orbitals.

Which statement best explains why water is an important molecule for living things?

The statement that best explains why water is essential for all living things is: Water is necessary for cellular functions.

Which reason best explains why carbon is able to form macromolecules quizlet?

The level of carbon in the atmosphere will increase. Which reason best explains why carbon is able to form macromolecules? Carbon can bond with many elements.

Why is carbon important in biology quizlet?

Why is Carbon So Important in Biological Molecules? carbon atoms bind readily together with each other forming long chains, branched molecules, rings and other shapes. The presence of functional groups produces further diversity among biological molecules.

Why is carbon so important?

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.

Which statement best represents how structure relates to function?

“Form follows function” means that the form of a body part or structure is related to its function.

What is the primary function of the carbon cycle?

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.

What is a carbon atom look like?

A carbon atom consists of a nucleus (center) with rings of moving electrons around it. Inside the nucleus are six protons (with a positive electrical charge) and six neutrons (with no electrical charge). Six electrons (with a negative charge) are around the nucleus.

How do carbon atoms form many organic compounds?

Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. There are millions of known carbon compounds, and carbon is the only element that can form so many different compounds.

What would most likely increase the amount of carbon in the environment?

Human activities such as burning fossil fuels and clearing vegetation have increased the concentration of carbon dioxide and of other greenhouse gases in the atmosphere.

What molecules both contain carbon atoms?

All organic compounds, such as proteins, carbohydrates, and fats, contain carbon, and all plant and animal cells consist of carbon compounds and their polymers. (Polymers are macromolecules consisting of many simple molecules bonded together in specific ways.)
