Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are primarily made of proteins.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes lower the activation energy required for reactions, thereby speeding up the rate of the reaction.

Front

What do enzymes typically end with?

Back

Enzymes typically end with the suffix '-ase', such as 'lactase' or 'amylase'.

Front

What is a substrate in the context of enzymes?

Back

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

Front

Where do substrates bind on an enzyme?

Back

Substrates bind to the active site of an enzyme.

Front

What is an active site?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.

Front

What factors can affect enzyme activity?

Back

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

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases the activity of an enzyme by binding to it.

Front

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

Back

Competitive inhibitors bind to the active site, while non-competitive inhibitors bind to a different part of the enzyme.

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.
