What is the function of an enzyme's active site?

Back

The active site is the specific region on an enzyme where substrates bind and undergo a chemical reaction.

Front

What is a substrate in the context of enzymes?

Back

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

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy required for a reaction to occur, making it easier for the reaction to proceed.

What happens to enzymes at high temperatures?

Back

High temperatures can denature enzymes, altering their shape and rendering them ineffective.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme's structure is altered, usually due to extreme conditions, affecting its function.

Front

What is the difference between enzymes and substrates?

Back

Enzymes are proteins that catalyze reactions, while substrates are the specific molecules that enzymes act upon.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to choose exact substrates from a group of similar chemical molecules.
