AP Bio: Unit 3 Year End Review Qs

Front

What is glycolysis?

Back

Glycolysis is a metabolic pathway that converts glucose into pyruvate, producing a net gain of 2 ATP molecules.

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the net ATP production of glycolysis?

Back

Glycolysis produces a net of 2 ATP.

Front

What type of reaction is glycolysis?

Back

Glycolysis is an anaerobic process, meaning it does not require oxygen.

Front

What is competitive inhibition?

Back

Competitive inhibition occurs when a substance mimics the substrate and competes for the active site of an enzyme.

Front

What is the role of malonic acid in enzyme inhibition?

Back

Malonic acid acts as a competitive inhibitor of succinate dehydrogenase, blocking the substrate from binding.

Front

What are endergonic reactions?

Back

Endergonic reactions are chemical reactions that require an input of energy to proceed.

Front

What are anabolic reactions?

Back

Anabolic reactions are nonspontaneous processes that build larger molecules from smaller ones, requiring energy input.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is a metabolic pathway that uses energy released by the oxidation of nutrients to produce ATP.

Front

What is the difference between competitive and noncompetitive inhibition?

Back

In competitive inhibition, the inhibitor competes with the substrate for the active site; in noncompetitive inhibition, the inhibitor binds to a different site, reducing enzyme activity.
