AP Biology Unit 3 Review

Front

What environmental conditions can cause denaturation of an enzyme?

Back

Extreme increase in temperature and pH changes.

Front

What will increase the rate of a reaction?

Back

Increase in amount of enzyme.

Front

What is FALSE about the Calvin cycle?

Back

It produces carbon dioxide.

Front

What process do muscle cells switch to when oxygen is low during heavy exercise?

Back

Anaerobic respiration (fermentation), which allows the cell to make small amounts of ATP in the absence of oxygen.

Front

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

Back

Glycolysis.

Front

Define denaturation in the context of enzymes.

Back

Denaturation is the process where an enzyme loses its functional shape due to environmental factors, leading to a loss of activity.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

What are the products of glycolysis?

Back

ATP, NADH, and pyruvate.

Front

Explain the significance of the light reactions in photosynthesis.

Back

Light reactions convert solar energy into chemical energy in the form of ATP and NADPH, which are used in the Calvin cycle.

Front

What is the main purpose of the Krebs cycle?

Back

To produce electron carriers (NADH and FADH2) for the electron transport chain.
