Photosynthesis — Flashcards

Answer

Photosynthesis is the process by which green plants, algae, and some bacteria use sunlight to synthesize food (glucose) from carbon dioxide and water. Oxygen is released as a by-product. This process …

Answer

The balanced equation is: $$ 6CO_2 + 12H_2O \rightarrow C_6H_{12}O_6 + 6H_2O + 6O_2 $$ Carbon dioxide and water, in the presence of sunlight and chlorophyll, produce glucose, water, and oxygen.

Answer

Photosynthesis occurs in the chloroplasts, which are green organelles found in plant cells. Chloroplasts contain chlorophyll, the pigment that captures light energy necessary for photosynthesis.

Answer

The two main stages are: 1. Light-dependent reactions (occur in thylakoids) 2. Light-independent reactions (Calvin cycle, occurs in stroma) The first stage captures light energy to make ATP and NADPH…

Answer

Chlorophyll is the green pigment in chloroplasts that absorbs light energy from the sun, primarily in the blue and red wavelengths. This energy is used to drive the light-dependent reactions of photos…

Answer

Other pigments include carotenoids (orange-yellow) and xanthophylls (yellow). These are accessory pigments that absorb different wavelengths of light and transfer energy to chlorophyll. They also prot…

Answer

Photolysis is the light-dependent splitting of water molecules (H₂O) into protons (H⁺), electrons (e⁻), and oxygen (O₂). This occurs in Photosystem II during the light reaction. The electrons replace …

Answer

The products are: - ATP (energy molecule) - NADPH (reducing agent) - O₂ (oxygen gas, released into atmosphere) These are produced in the thylakoid membranes using light energy and water.
