AP Biology: Unit 3 Enzymes

Front

What is the primary structure of a protein?

Back

The primary structure of a protein is the linear sequence of amino acids linked by peptide bonds.

Front

What happens to enzymes at high temperatures?

Back

High temperatures can lead to denaturation of enzymes, altering their structure and function.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions by lowering the activation energy.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external stress, such as temperature or pH changes.

Front

What is the active site of an enzyme?

Back

The active site is the specific region on an enzyme where the substrate binds and the reaction occurs.

Front

What is a catabolic reaction?

Back

A catabolic reaction is a metabolic process that breaks down molecules into smaller units, releasing energy.

Front

What is an anabolic reaction?

Back

An anabolic reaction is a metabolic process that builds larger molecules from smaller units, requiring energy.

Front

How does temperature affect enzyme activity?

Back

An increase in temperature generally increases enzyme activity up to a certain point, as it raises the kinetic energy of molecules.

Front

What are substrates in enzymatic reactions?

Back

Substrates are the reactants that enzymes act upon during a biochemical reaction.

Front

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

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to a different site, altering enzyme function.
