What is the role of chlorophyll in photosynthesis?

• It provides the green pigment
• It converts light energy into chemical energy

During the light-independent reactions (Calvin cycle), what is the role of the enzyme rubisco?

• To convert light energy into chemical energy
• To catalyse the fixation of carbon dioxide
• To transport electrons in the electron transport chain
• To synthesise glucose from carbon dioxide and water

What is the primary function of the stroma in chloroplasts?

• To house the thylakoid membranes
• To facilitate the light-dependent reactions
• To store the products of photosynthesis
• To carry out the light-independent reactions

Which of the following is not one of the three main stages of photosynthesis?
