Sample Questions

1multiple choice

The dark reaction of photosynthesis takes place in the:

Show answer

Stroma of chloroplast

The dark reaction (Calvin cycle) takes place in the stroma of the chloroplast, where all necessary enzymes for CO2 fixation are located.

2multiple choice

The light reaction of photosynthesis occurs in the:

Show answer

Thylakoid membranes / Grana

The light reaction occurs on the thylakoid membranes within the grana of the chloroplast. This is where pigments are located and light energy is captured.

3true false

Chlorophyll a is the primary photosynthetic pigment.

Show answer

True

Chlorophyll a is the primary (main) photosynthetic pigment. It is the only pigment directly involved in the light reaction's photochemical act at the reaction centre.

4multiple choice

What is the first stable product of the Calvin (C3) cycle?

Show answer

3-Phosphoglycerate (3-PGA)

3-PGA (3-phosphoglycerate) is the first stable 3-carbon compound formed when CO2 combines with RuBP via RuBisCo in the Calvin cycle.
