Front

What is active transport?

Back

Active transport is the process by which cells use ATP energy to move molecules against their concentration gradient, from areas of low concentration to areas of high concentration.

Front

In which phase of the cell cycle does DNA replication occur?

Back

DNA replication occurs during the S phase of the cell cycle.

Front

What type of cells have membrane-bound organelles?

Back

Eukaryotic cells have membrane-bound organelles.

Front

Which types of cells contain ribosomes?

Back

Both prokaryotic and eukaryotic cells contain ribosomes.

Front

What is a peptide bond?

Back

A peptide bond is a covalent bond that links amino acids together in a protein.

Front

What enzyme breaks down peptide bonds?

Back

The enzyme peptidase breaks down peptide bonds.

Front

What is the end product of protein digestion in the small intestine?

Back

The end product of protein digestion in the small intestine is amino acids.

Front

What is the role of ATP in active transport?

Back

ATP provides the energy required for active transport to move molecules against their concentration gradient.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves molecules down their concentration gradient, while active transport requires energy to move molecules against their concentration gradient.

Front

What are organelles?

Back

Organelles are specialized structures within a cell that perform specific functions.
