Front

What is a reactant in photosynthesis?

Back

A reactant in photosynthesis is a substance that is consumed during the process. In this case, carbon dioxide is a key reactant.

Front

List the stages of the cell cycle in order.

Back

The stages of the cell cycle in order are: G1, S, G2, M.

Front

During which phase of cellular respiration is carbon dioxide released?

Back

Carbon dioxide is released during the Krebs's cycle.

Front

How is energy released from ATP?

Back

Energy is released from ATP when a phosphate group is removed.

Front

What does a single thylakoid represent?

Back

A single thylakoid is a membrane-bound compartment inside chloroplasts, involved in the light-dependent reactions of photosynthesis.

Front

Define 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 the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

What is the function of the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats, and proteins.

Front

What is glycolysis?

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP and NADH in the process.
