Back

A substrate is the reactant that an enzyme acts 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.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external stress, such as heat.

Front

What role do enzymes play in digestion?

Back

Enzymes break down food into smaller molecules that can be absorbed by the body.

Front

What is the relationship between enzymes and activation energy?

Back

Enzymes lower the activation energy required for a chemical reaction to occur.
