AP Biology- Enzymes and Energy

Front

What type of reaction is represented by A + B --> AB + Energy?

Back

Exergonic reaction: A reaction that releases energy.

Front

What is true for anabolic pathways?

Back

Anabolic pathways consume energy to build polymers from monomers.

Front

What type of inhibition blocks the active site of an enzyme?

Back

Competitive inhibition: It occurs when a substance competes with the substrate for the active site.

Front

Where is energy stored in ATP?

Back

In the bonds between phosphate groups.

Front

What is the term for a reaction that requires a net intake of energy?

Back

Endergonic reaction: A reaction that absorbs energy.

Front

Define enzymes.

Back

Enzymes are biological catalysts that speed up chemical reactions without being consumed.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes lower the activation energy required for reactions to occur.

Front

What is the difference between exergonic and endergonic reactions?

Back

Exergonic reactions release energy, while endergonic reactions require energy input.

Front

What is allosteric inhibition?

Back

Allosteric inhibition occurs when an inhibitor binds to a site other than the active site, changing the enzyme's shape.

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant that an enzyme acts upon.
