Front

What is the process called that involves the movement of molecules across a membrane via protein channels?

Back

Facilitated diffusion

Front

What is the cell structure that contains genetic material and controls the cell's activities?

Back

Nucleus

Front

What is the primary function of the cell membrane?

Back

To regulate the movement of substances in and out of the cell.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What role do enzymes play in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

What is the significance of the concentration gradient in diffusion?

Back

The concentration gradient drives the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.
