Question

question 7
energy produced during the light reactions is used:

to produce carbon dioxide
to breakdown atp in the mitochondria
by the cell for movement
to produce glucose in the calvin cycle
to produce oxygen

Explanation:

During photosynthesis, the light reactions produce ATP and NADPH. These energy - rich molecules are then used in the Calvin cycle (the light - independent reactions) to convert carbon dioxide into glucose.

• Carbon dioxide is taken in from the atmosphere and is not produced using the energy from the light reactions.
• ATP is produced in the light reactions (not broken down in the mitochondria using light - reaction energy). Mitochondria are involved in cellular respiration.
• The energy from the light reactions is not directly used for cell movement.
• Oxygen is a by - product of the light reactions (produced from the splitting of water), not something that the energy from the light reactions is used to produce.

Answer:

to produce glucose in the Calvin cycle
