AP Bio Unit 3 Review

Front

What happens to enzymes when they are heated to a high temperature?

Back

They denature.

Front

What is the optimum pH of the enzyme based on the given graph?

Back

The optimum pH of the enzyme is 6.6.

Front

What is the term for the molecule that an enzyme acts upon?

Back

Front

Where do the light-dependent reactions of photosynthesis take place?

Back

Within the thylakoid membranes.

Front

Define denaturation in the context of enzymes.

Back

Denaturation is the process where an enzyme loses its functional shape due to high temperature or extreme pH, rendering it inactive.

Front

What is the role of the active site in an enzyme?

Back

The active site is the region on the enzyme where substrate molecules bind and undergo a chemical reaction.

Front

Explain the significance of pH in enzyme activity.

Back

Enzymes have an optimum pH range where they function best; deviations can lead to decreased activity or denaturation.

Front

What is fermentation and why do cells undergo this process?

Back

Fermentation is an anaerobic process that allows cells to generate energy without oxygen, often producing byproducts like lactic acid.
