Question

Which statement describes the light reaction of photosynthesis?

O
Carbon dioxide is put together with glucose.
O
Water molecules are split apart.
O
Air and water create energy for a plant.
O Water molecules are combined to make food.

Answer 1

The correct option is B) Water molecules are split apart.

Step-by-step explanation:

Photosynthesis can be described as a process in which plants make glucose and oxygen from carbon dioxide and water in the presence of sunlight. There are two main types of reactions occurring during this process which are known as the light reactions and the dark reactions.

During the light reactions, energy from the sun is used to drive electrons from the water molecule. ATP and NADPH molecules are generated temporarily which are used during the dark reactions.
