Answer 1

Hint: Both are the constituents of proteins.

Complete answer:
Difference between hormone and enzyme

Hormone	Enzyme
It acts as a catalyst which accelerates the rate of reaction.	It acts as a messenger that triggers the functions in the body.
It is made up of proteins.	It is made up of proteins, amino acids, steroids, etc.
They are highly specific and perform specific functions.	They are nonspecific and perform various functions.
They are secreted by exocrine glands.	They are secreted by endocrine glands.
They are affected by external factors like pH, temperature, etc.	They are not affected by external factors.
They do not transport from one part of the cell to another.	They transport from different parts of the cell.
They have a higher molecular weight.	They have a lower higher molecular weight.
They act quickly.	Some are fast while some may be slow.
As the concentration increases, the rate of reaction increases.	An increase or decrease in hormone will result in deficiency or overproduction.
They cannot diffuse through the cell membrane.	They can diffuse through the cell membrane.
Example: Oxidoreductases, hydrolases, etc.	Example: Insulin, Thyroxine, etc.

Note: Enzymes are of six types: Oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases while hormones have two types of glands: exocrine and endocrine glands.
