AP Bio Unit 3

Front

What is the optimum temperature for enzyme X's rate of reaction?

Back

97 degrees Fahrenheit.

Front

How does a decrease in temperature to 92 degrees Fahrenheit affect enzyme X's rate of reaction?

Back

It decreases the rate of reaction due to a change in the shape of the protein.

Front

What effect does adding an enzyme to a reaction have on activation energy?

Back

It decreases the activation energy.

Front

What is the primary function of ATP synthase?

Back

To create ATP during chemiosmosis.

Front

How is chemiosmosis best described?

Back

The use of a proton gradient to power ATP synthase and produce ATP.

Front

What is the main purpose of the Krebs Cycle?

Back

To break down pyruvate to produce electron carrier molecules, FADH2 and NADH, as well as CO2 and ATP as byproducts.

Front

What are the byproducts of the Krebs Cycle?

Back

FADH2, NADH, CO2, and ATP.

Front

What role do electron carrier molecules play in cellular respiration?

Back

They transport electrons to the electron transport chain, facilitating ATP production.

Front

What is the relationship between temperature and enzyme activity?

Back

Enzyme activity typically increases with temperature up to an optimum point, after which it decreases.

Front

Define activation energy in the context of chemical reactions.

Back

Activation energy is the minimum energy required for a chemical reaction to occur.
