AP Biology - Unit 3 Review

Front

What is the site called where activators and inhibitors bind to an enzyme, other than the active site?

Back

Allosteric site

Front

Which molecule is NOT produced during the Calvin Cycle in photosynthesis?

Back

FADH2

Front

What type of reactions are anabolic reactions?

Back

Nonspontaneous reactions that build molecules.

Front

In the process of forming an ADP molecule, which bonds must be broken?

Back

Bonds between C and D.

Front

What is the primary 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

Define photosynthesis.

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of NADPH in photosynthesis?

Back

NADPH acts as a reducing agent, providing the electrons needed for the reduction of carbon dioxide in the Calvin Cycle.

Front

What is the difference between competitive and allosteric inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while allosteric inhibition occurs when an inhibitor binds to a site other than the active site, changing the enzyme's shape.

Front

What is the function of RuBisCO in the Calvin Cycle?

Back

RuBisCO catalyzes the reaction between carbon dioxide and ribulose bisphosphate (RuBP) to initiate the Calvin Cycle.

Front

What are the end products of glycolysis?

Back

2 pyruvate, 2 ATP, and 2 NADH.
