AP Biology - Unit 3 Review

Front

What is the location where the enzyme and substrate bind?

Back

Active site

Front

What is chemiosmosis best described as?

Back

The use of a proton gradient to power ATP Synthase and produce ATP

Front

What happens when an enzyme's active site is blocked by a competitive inhibitor?

Back

The enzyme's active site is blocked, preventing substrate binding.

Front

What do endergonic reactions require?

Back

An input of energy

Front

Which enzyme functions best in acidic environments?

Back

Enzyme A

Front

Define an enzyme.

Back

A protein that acts as a catalyst to speed up chemical reactions.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell.

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.

Front

What is the function of ATP Synthase?

Back

ATP Synthase synthesizes ATP from ADP and inorganic phosphate using a proton gradient.

Front

What is the significance of the proton gradient in cellular respiration?

Back

The proton gradient drives ATP production during chemiosmosis.
