Bio Test Unit 4 Part 2 Review

Front

What is a substance that is acted upon by an enzyme called?

Back

Substrate

Front

What term describes a situation where a molecule can occupy the same active site as the substrate?

Back

Inhibition

Front

What three letters do enzymes typically end with?

Back

-ase

Front

What is the term for the unique fit between an enzyme and its substrate?

Back

Specificity

Front

What is the term for the complex formed when an enzyme binds to its substrate?

Back

Enzyme-substrate complex

Front

What is the role of a coenzyme in enzymatic reactions?

Back

Coenzymes assist enzymes in catalyzing reactions.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape.

Front

What is the function of an active site on an enzyme?

Back

The active site is where the substrate binds to the enzyme.

Front

What is feedback inhibition?

Back

Feedback inhibition is a regulatory mechanism where the end product of a pathway inhibits an earlier step.

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; non-competitive inhibition occurs when an inhibitor binds to a different site.
