Photosynthesis Review

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 Calvin Cycle (light-independent reactions).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in the chloroplasts of plants that absorbs light energy, primarily in the blue and red wavelengths, and is essential for photosynthesis.

Front

What are photoautotrophs?

Back

Photoautotrophs are organisms that produce their own food using light energy, such as plants and some bacteria.

Front

What is the primary product of the Calvin Cycle?

Back

The primary product of the Calvin Cycle is glucose, which is a simple sugar used by plants for energy.

Front

What is the significance of G3P in photosynthesis?

Back

Glyceraldehyde-3-phosphate (G3P) is an important intermediate in the synthesis of glucose and other carbohydrates during photosynthesis.

Front

What is the function of NADPH in photosynthesis?

Back

NADPH is a reducing agent that provides the electrons needed for the reduction of carbon dioxide to glucose in the Calvin Cycle.

Front

What is the role of water in photosynthesis?

Back

Water is split during the light-dependent reactions to provide electrons, protons, and oxygen; oxygen is released as a byproduct.

Front

What is the function of ATP in photosynthesis?

Back

ATP provides the energy required for various biochemical reactions in the Calvin Cycle and other cellular processes.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume organic molecules from other organisms for energy.
