What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions by lowering the activation energy required.

Front

What is activation energy?

Back

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

Front

What is a substrate in the context of enzymes?

Back

A substrate is the specific reactant that an enzyme acts upon.

Front

What does enzyme specificity mean?

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 that can affect enzyme activity include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is denaturation in enzymes?

Back

Denaturation is the process in which an enzyme loses its functional shape due to external factors like temperature or pH changes.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is the primary function of lipids?

Back

The primary function of lipids is to store energy and provide insulation.
