AP Biology Unit 3 Review

Front

What is the main purpose of the electron transport chain in cellular respiration?

Back

To generate a proton gradient for ATP synthesis.

Front

What are the products of the light reactions of photosynthesis?

Back

NADPH, ATP, and O2.

Front

The function of fermentation is to regenerate ______ so that glycolysis can continue to produce ATP.

Back

NAD+.

Front

Which process releases energy in glucose to form ATP, NADH, and pyruvate?

Back

Glycolysis.

Front

What reactants do plants use for the light reaction?

Back

Water, NADP+, and ADP.

Front

Define glycolysis.

Back

The process of breaking down glucose to produce ATP, NADH, and pyruvate.

Front

What is oxidative phosphorylation?

Back

The process of ATP production that occurs in the mitochondria, using the electron transport chain and chemiosmosis.

Front

What is the role of NADPH in photosynthesis?

Back

NADPH is used as a reducing agent in the Calvin cycle to convert carbon dioxide into glucose.

Front

Explain the Krebs Cycle.

Back

A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

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

Back

It drives ATP synthesis through ATP synthase during oxidative phosphorylation.
