Proteins and Enzymes

Front

What is an enzyme?

Back

An enzyme is a type of protein that acts as a catalyst to speed up chemical reactions in the body.

Front

What is the role of the active site in 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?

Back

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

Front

What happens to enzymes at high temperatures?

Back

Enzymes can become denatured, meaning their shapes are altered, which affects their ability to function.

Front

What is denaturation?

Back

Denaturation is the process in which proteins lose their structure due to external stress, such as heat or pH changes.

Front

What is the optimum pH for an enzyme?

Back

The optimum pH is the pH level at which an enzyme is most active and efficient.

Front

How do enzymes affect the activation energy of a reaction?

Back

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

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to a different part of the enzyme.

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What is the significance of enzyme specificity?

Back

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