Stages of Photosynthesis quiz Flashcards

The two main stages of photosynthesis are the light reactions and the Calvin cycle.

The light reactions occur inside the thylakoids of the chloroplast.

The primary reactants used in the light reactions are light (photons) and water.

The main products of the light reactions are oxygen gas and chemical energy (ATP and NADPH).

The Calvin cycle takes place in the stroma of the chloroplast.

The Calvin cycle uses carbon dioxide from the atmosphere and chemical energy produced by the light reactions to synthesize glucose.

Chloroplasts act as the site of photosynthesis, where both the light reactions and the Calvin cycle occur.

The inputs of photosynthesis are solar energy, water, and carbon dioxide, while the outputs are oxygen gas and glucose.

The Calvin cycle is responsible for generating glucose.

ATP, produced during the light reactions, provides the chemical energy needed for the Calvin cycle to synthesize glucose.

Oxygen gas is produced during the light reactions when water molecules are split.

NADPH provides the reducing power needed to convert carbon dioxide into glucose in the Calvin cycle.

The light reactions produce ATP and NADPH, which are then used by the Calvin cycle to synthesize glucose from carbon dioxide.

The primary function of the thylakoids is to house the light reactions, where light energy is converted into chemical energy.

The stroma is the site of the Calvin cycle, where carbon dioxide is fixed into glucose using the energy from ATP and NADPH.
