AP Biology- Enzymes and Energy

Front

What are enzymes made up of?

Back

Enzymes are made up of amino acids.

Front

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

Back

This is an exergonic reaction.

Front

What role does Vitamin C play in enzymatic reactions?

Back

Vitamin C acts as a coenzyme.

Front

Define metabolism in the context of biology.

Back

Metabolism is all the energy transformation reactions in an organism.

Front

What does the term 'net release of energy' refer to?

Back

It refers to an exergonic reaction.

Front

What is the function of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions.

Front

What is the significance of activation energy in enzyme-catalyzed reactions?

Back

Activation energy is the energy required to initiate a reaction; enzymes lower this energy barrier.

Front

How do temperature and pH affect enzyme activity?

Back

Enzymes have optimal temperature and pH ranges; deviations can reduce their activity or denature them.

Front

What is a substrate in the context of enzyme activity?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to a different site, altering enzyme function.
