What is the primary form of energy used by cells?

Back

ATP (Adenosine Triphosphate) is the primary form of usable energy in cells.

Front

In a 20% salt solution placed in dialysis tubing, where will the water move when added to distilled water?

Back

The water will move into the dialysis tubing (20% salt solution) due to osmosis.

Front

What is the function of the nucleus in a cell?

Back

The nucleus contains DNA that controls the production of proteins.

Front

What process allows small molecules to passively leave the digestive system and enter the blood?

Back

Diffusion allows small molecules to pass through cell membranes.

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy.

Front

What is the difference between active transport and passive transport?

Back

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

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.
