AP Biology: Unit 3 Review (CED)

Front

What is the active site of an enzyme?

Back

The active site is the specific region on an enzyme where the substrate binds, facilitating the enzyme's catalytic activity.

Front

What can cause denaturation of an enzyme?

Back

Denaturation of an enzyme can be caused by extreme increases in temperature and changes in pH, leading to the loss of its functional shape.

Front

Where is the electrochemical gradient of protons generated in cellular respiration?

Back

The electrochemical gradient of protons is generated in the intermembrane space of the mitochondria during the electron transport chain.

Front

How can the rate of a reaction be increased?

Back

The rate of a reaction can be increased by increasing the concentration of the enzyme.

Front

What is required to maintain order in cellular processes?

Back

To maintain order in cellular processes, energy input must exceed energy loss.

Front

What is an allosteric site on an enzyme?

Back

An allosteric site is a site on an enzyme other than the active site, where molecules can bind and influence the enzyme's activity.

Front

What is the role of enzymes in biochemical reactions?

Back

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

Front

What happens to enzymes at extreme temperatures?

Back

At extreme temperatures, enzymes can denature, losing their shape and functionality.

Front

What is the function of the cristae in mitochondria?

Back

Cristae are the folds in the inner mitochondrial membrane that increase the surface area for the electron transport chain and ATP production.

Front

What is the significance of the matrix in mitochondria?

Back

The matrix is the innermost compartment of mitochondria where the Krebs cycle occurs, producing electron carriers for the electron transport chain.
