Cell Energy and Cellular Transport Review

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

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 the role of ATP in cells?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space, which drives the movement of substances from areas of high concentration to areas of low concentration.

Front

What happens in a hypotonic solution?

Back

In a hypotonic solution, the concentration of solute outside the cell is lower than inside, causing water to enter the cell, which may lead to cell swelling or bursting.

Front

What happens in a hypertonic solution?

Back

In a hypertonic solution, the concentration of solute outside the cell is higher than inside, causing water to leave the cell, which may lead to cell shrinkage.

Front

What is an isotonic solution?

Back

An isotonic solution has equal concentrations of solute inside and outside the cell, resulting in no net movement of water.

Front

What are the reactants of cellular respiration?

Back

The reactants of cellular respiration are glucose and oxygen.

Front

What is the significance of photosynthesis to the ecosystem?

Back

Photosynthesis is crucial for the ecosystem as it produces oxygen and organic compounds that serve as food for other organisms.
