AP Biology Unit 3 Review

Front

What is denaturation of an enzyme?

Back

Denaturation is the process in which an enzyme loses its functional shape due to environmental factors such as extreme temperature or pH changes.

Front

What are the light-dependent reactions of photosynthesis?

Back

The light-dependent reactions are the first stage of photosynthesis where sunlight is converted into chemical energy in the form of ATP and NADPH.

Front

What factors can increase the rate of a chemical reaction?

Back

Factors include increasing the concentration of substrates, increasing temperature, and adding more enzymes.

Front

What is glycolysis?

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process.

Front

Where does the substrate bind on an enzyme?

Back

The substrate binds to the active site of the 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

What is the function of NADPH in photosynthesis?

Back

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

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 Krebs Cycle?

Back

The Krebs Cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using energy derived from the electron transport chain.
