Enzymes

Front

What are enzymes?

Back

Enzymes are proteins that act as biological catalysts, speeding up chemical reactions in the body.

Front

What happens to an enzyme when it is denatured?

Back

It loses its shape, which affects its ability to function.

Front

What is the effect of high temperatures on enzymes?

Back

High temperatures can denature enzymes, altering their shape and function.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy needed for reactions, making them occur more easily.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where substrate molecules 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

What is enzyme specificity?

Back

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

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is a coenzyme?

Back

A coenzyme is a non-protein molecule that assists enzymes in catalyzing reactions.
