AP Biology: Unit 3 Review (CED)

Front

What is the effect on free energy when the amount of enzyme is doubled?

Back

No effect on free energy.

Front

Where does the Calvin cycle occur in a plant cell?

Back

Stroma.

Front

To maintain order and power in cellular processes, what must be true about energy input and loss?

Back

Energy input must exceed energy loss.

Front

In which type of organisms did photosynthesis first evolve?

Back

Prokaryotic organisms.

Front

What factor can increase the rate of a biochemical reaction?

Back

Increase enzyme.

Front

Define enzyme.

Back

A protein that acts as a catalyst to speed up biochemical reactions.

Front

What is the role of the stroma in photosynthesis?

Back

It is the site where the Calvin cycle takes place.

Front

What is the relationship between substrate concentration and reaction rate?

Back

Increasing substrate concentration can increase the reaction rate until a saturation point is reached.

Front

What is the primary function of the thylakoid membrane?

Back

It is where the light-dependent reactions of photosynthesis occur.

Front

What is the significance of energy input exceeding energy loss in cells?

Back

It allows cells to maintain order and perform necessary functions.
