Front

What are the four major biological macromolecules?

Back

Carbohydrates, Lipids, Proteins, Nucleic Acids.

Front

What is the primary function of nucleic acids?

Back

Storing and transmitting genetic information.

Front

What is the building block of proteins?

Back

Amino acids.

Front

What type of macromolecule is primarily used for energy storage?

Back

Carbohydrates.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions by lowering activation energy.

Front

What happens to pepsin when it enters the small intestine?

Back

It becomes inactive due to the change in pH.

Front

What are lipids primarily composed of?

Back

Fatty acids and glycerol.

Front

What is the significance of the pH level in the stomach?

Back

The low pH (around 2) activates pepsinogen to pepsin, which digests proteins.

Front

What is the difference between DNA and RNA?

Back

DNA stores genetic information, while RNA transmits genetic information and helps in protein synthesis.

Front

What is a catalyst?

Back

A substance that increases the rate of a chemical reaction without being consumed.
