8.5-Cell Unit Review 24-25

Front

What is Active Transport?

Back

Active Transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy (ATP).

Front

What is Passive Transport?

Back

Passive Transport is the movement of substances across a cell membrane without the need for energy, following the concentration gradient.

Front

What is Osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is Facilitated Diffusion?

Back

Facilitated Diffusion is the process of transporting substances across a cell membrane with the help of carrier proteins, without using energy.

Front

What is the optimum pH for enzyme activity?

Back

The optimum pH is the pH at which an enzyme's activity is at its maximum.

Front

What is an immune response?

Back

An immune response is the body's defense mechanism against pathogens, which includes fever, inflammation, and the production of antibodies.

Front

What is a monomer?

Back

A monomer is a small, basic molecular unit that can join together to form polymers. For example, amino acids are the monomers of proteins.

Front

What are proteins made of?

Back

Proteins are made of long chains of amino acids linked together by peptide bonds.

Front

What is the role of ATP in cells?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

What is the function of carbon dioxide in photosynthesis?

Back

Carbon dioxide is used by plants during photosynthesis to produce glucose and oxygen.
