Module 2 Review KEYSTONE questions

Front

What is photosynthesis?

Back

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

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells break down glucose and other organic molecules to produce ATP, releasing energy for cellular activities.

Front

What is the role of ATP in living organisms?

Back

ATP (adenosine triphosphate) captures and transfers energy released by the breakdown of glucose, serving as the primary energy currency of the cell.

Front

How are photosynthesis and cellular respiration related?

Back

Photosynthesis provides the glucose and oxygen needed for cellular respiration, while cellular respiration produces carbon dioxide and water, which are used in photosynthesis.

Front

What is the function of mitochondria?

Back

Mitochondria are organelles that produce ATP through cellular respiration, supplying energy needed for various cellular processes.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What are the byproducts of photosynthesis?

Back

The byproducts of photosynthesis are glucose and oxygen.

Front

What are the byproducts of cellular respiration?

Back

The byproducts of cellular respiration are carbon dioxide and water.

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

How does the skin function similarly to bacterial cell walls?

Back

The skin acts as a protective barrier, similar to bacterial cell walls, which provide structure and protection to bacterial cells.
