Cell Energy and Cellular Transport Review

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 relationship between photosynthesis and respiration?

Back

Photosynthesis and respiration are opposite processes; photosynthesis converts carbon dioxide and water into glucose and oxygen using sunlight, while respiration breaks down glucose and oxygen to produce carbon dioxide and water, releasing energy.

Front

Where is the concentration of a substance typically lowest in a solution?

Back

The concentration of a substance is typically lowest at the bottom of a cup when a dye is added, as it diffuses from areas of higher concentration to lower concentration.

Front

How do plants produce glucose?

Back

Plants produce glucose by using light energy during the process of photosynthesis, converting carbon dioxide and water into glucose and oxygen.

Front

What is ATP?

Back

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

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and structural support.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space, driving the movement of substances during diffusion and osmosis.
