Enzymes

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms by lowering the activation energy.

Front

How do enzymes increase the speed of chemical reactions?

Back

Enzymes increase the speed of chemical reactions by reducing the activation energy required for the reaction to occur.

Front

What does it mean for an enzyme to be substrate specific?

Back

An enzyme is substrate specific when it can only catalyze a reaction for a particular substrate due to the specific shape of its active site.

Front

What is the typical ending for enzyme names?

Back

Enzyme names typically end with the suffix '-ase'.

Front

What are enzymes composed of?

Back

Enzymes are composed of amino acids, which are the building blocks of proteins.

Front

What type of macromolecule are enzymes classified as?

Back

Enzymes are classified as proteins.

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

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 a substrate in the context of enzymes?

Back

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

Front

What is an enzyme inhibitor?

Back

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