Front

What determines a macromolecule's function?

Back

A macromolecule's structure ultimately determines its function.

Front

Which cell has a greater surface-area-to-volume ratio if two cells have the same shape?

Back

The smallest cell has a greater surface-area-to-volume ratio.

Front

How does ATP allow chemical reactions to occur?

Back

ATP releases energy when hydrolyzed.

Front

What is a molecule that binds to the active site of an enzyme and prevents a reaction called?

Back

A Competitive Inhibitor.

Front

What describes the PRIMARY level of protein organization?

Back

Amino acids joined together with covalent bonds via dehydration synthesis.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions.

Front

What is the significance of the surface-area-to-volume ratio in cells?

Back

A higher surface-area-to-volume ratio allows for more efficient exchange of materials.

Front

What is dehydration synthesis?

Back

A process where two molecules are joined together with the removal of water.

Front

What is the difference between competitive and non-competitive inhibitors?

Back

Competitive inhibitors bind to the active site, while non-competitive inhibitors bind to another part of the enzyme.

Front

What are R-groups in proteins?

Back

R-groups are side chains that determine the properties and functions of amino acids.
