Enzymes

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms.

Front

What is the role of the active site in an enzyme?

Back

The active site is the region on the enzyme where the substrate binds and the reaction occurs.

Front

Which of the following is an example of an enzyme? Amylase, Sucrose, Fructose, Saccharide

Back

Amylase is an enzyme that helps in the digestion of carbohydrates.

Front

What is a substrate in the context of enzymes?

Back

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

Front

What happens to enzymes at high temperatures?

Back

High temperatures can denature enzymes, altering their structure 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 required for a reaction, allowing it to proceed faster.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently.

Front

What is denaturation in enzymes?

Back

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

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can reduce activity or denature the enzyme.
