AP Biology Unit 3: Cellular Energetics Review

Front

What are the products of the light reaction in photosynthesis?

Back

ATP and NADPH are produced during the light reactions and are essential for the Calvin cycle.

Front

What factors can affect the initial rate of an enzyme reaction?

Back

Enzyme concentration, substrate concentration, temperature, and pH can all affect the initial rate of an enzyme reaction.

Front

What are the main products of glycolysis?

Back

The main products of glycolysis are pyruvate, ATP, water, and NADH.

Front

How do plants obtain carbon for glucose formation?

Back

Plants obtain carbon necessary for glucose formation through CO2 absorbed from the atmosphere.

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 NADPH and its function in photosynthesis?

Back

NADPH is a reducing agent that provides the electrons needed for the reduction of carbon dioxide in the Calvin cycle.

Front

Define glycolysis.

Back

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

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, where CO2 is fixed into glucose.

Front

Explain the importance of enzyme concentration in biochemical reactions.

Back

Higher enzyme concentration generally increases the rate of reaction, provided there is enough substrate available.

Front

What is the effect of temperature on enzyme activity?

Back

Temperature affects enzyme activity; each enzyme has an optimal temperature range where it functions best.
