Biology Flashcard 9.2 Photosynthesis: An Overview

Front

What is the by-product produced during photosynthesis from the plant/autotrophs perspective?

Back

Oxygen

Front

True or False: NADP+ and a hydrogen ion (H+) form NADPH because it 'carries' two high energy electrons (2e-).

Back

TRUE

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 are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: @@6CO_2 + 6H_2O + light ightarrow C_6H_{12}O_6 + 6O_2@@.

Front

What is the significance of oxygen produced during photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of aerobic organisms, including humans, as it is used in cellular respiration.

Front

What are light-dependent reactions?

Back

Light-dependent reactions are the first stage of photosynthesis that convert light energy into chemical energy in the form of ATP and NADPH.

Front

What are light-independent reactions (Calvin cycle)?

Back

Light-independent reactions, or the Calvin cycle, use ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.
