What is the function of a capsid in a virus?

Back

The capsid protects the genetic information of the virus.

Front

What is the role of the nuclear membrane in animal cells?

Back

The nuclear membrane protects the genetic information within the nucleus.

Front

How do enzymes affect chemical reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy.

Front

What cellular process occurs in ribosomes attached to the endoplasmic reticulum?

Back

The synthesis of new proteins.

Front

What biomolecule contains both nitrogen and phosphate?

Front

What is the primary role of enzymes in living cells?

Back

To speed up chemical reactions.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

What is the difference between a virus and a living cell?

Back

Viruses cannot reproduce on their own and require a host cell, while living cells can reproduce independently.

Front

What is the structure of a virus?

Back

A virus typically consists of genetic material (DNA or RNA) surrounded by a protein coat called a capsid.

Front

What is the endoplasmic reticulum's function in a cell?

Back

The endoplasmic reticulum synthesizes proteins and lipids.
