Unit 3 practice ap bio

Front

What is the site called where activators and inhibitors bind to an enzyme, other than the active site?

Back

Allosteric site

Front

What process do muscle cells switch to when they run out of oxygen during heavy weightlifting?

Back

Anaerobic respiration

Front

What is the sum of all chemical reactions in a living organism called?

Back

Metabolism

Front

Which enzyme in the electron transport chain is responsible for generating ATP molecules?

Back

ATP synthase

Front

Which process is most directly driven by light energy?

Back

Removal of electrons from membrane-bound chlorophyll molecules

Front

Define 'competitive inhibition' in the context of enzyme activity.

Back

Competitive inhibition occurs when a substance competes with the substrate for binding to the active site of an enzyme.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, providing energy for various biochemical reactions.

Front

Explain the difference between aerobic and anaerobic respiration.

Back

Aerobic respiration requires oxygen to produce ATP, while anaerobic respiration occurs in the absence of oxygen and produces less ATP.

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to convert carbon dioxide and water into glucose and oxygen.

Front

What is the primary purpose of the Krebs cycle?

Back

The Krebs cycle generates electron carriers (NADH and FADH2) and ATP through the oxidation of acetyl-CoA.
