Enzymes

Front

What is an enzyme-substrate complex?

Back

An enzyme-substrate complex is a temporary molecule formed when an enzyme comes into contact with its substrate. It is the intermediate state in the enzyme-catalyzed reaction.

Front

What do enzymes typically end with?

Back

Enzymes typically end with the suffix '-ase', indicating their function as catalysts.

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule upon which an enzyme acts. It binds to the enzyme's active site.

Front

What is the primary function of an enzyme?

Back

The primary function of an enzyme is to speed up chemical reactions by lowering the activation energy required for the reaction to occur.

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 active site of an enzyme?

Back

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

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy needed for a reaction, allowing it to proceed more quickly.

Front

Can enzymes be reused?

Back

Yes, enzymes can be reused multiple times in chemical reactions as they are not consumed in the reaction.

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 an inhibitor in enzyme activity?

Back

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