AP Biology: Unit 3 Review (CED)

Front

What is the principle of energy input in cellular processes?

Back

Energy input must exceed energy loss to maintain order and power cellular processes.

Front

Where does the Calvin cycle occur in the chloroplast?

Back

The Calvin cycle takes place in the stroma.

Front

What environmental conditions can lead to enzyme denaturation?

Back

Extreme increase in temperature and pH changes can cause denaturation of enzymes.

Front

What is energy coupling in biochemical reactions?

Back

Energy coupling is the process where an endergonic reaction is fueled by an exergonic reaction.

Front

Where does the electron transport chain occur?

Back

The electron transport chain takes place in chloroplasts, prokaryotic plasma membrane, and mitochondria.

Front

Define an endergonic reaction.

Back

An endergonic reaction is a reaction that requires energy input to proceed.

Front

Define an exergonic reaction.

Back

An exergonic reaction is a reaction that releases energy.

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 cellular functions.

Front

What is the function of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions by lowering the activation energy.

Front

What is the significance of the stroma in photosynthesis?

Back

The stroma is the site of the Calvin cycle, where carbon fixation occurs.
