Question

The chemical reaction for photosynthesis is 6 CO2 + 12 H2O + light

Answer 1

Answer:

B. During the light reactions of photosynthesis, water is split, removing electrons and protons, and oxygen gas is released.

Explanation:

In Photosynthesis two phases occurs. They are grouped into light dependent and light independent phase (dark phase) reactions. In the light dependent phase, sunlight is trapped by chlorophyll and water is split into its components ( oxygen, hydrogen ions and free electrons; photolysis). Part of the electrons and the hydrogen ions are picked up by NADP (Nicotinamide adenine dinucleotide phosphate) converting it to NADPH and part of the electrons are used to replenished the photosystems trapping the sunlight.  

Answer 2

Answer:A

Explanation:

The light phase reaction involves the photolysis of water. Sunlight splits water up and the hydrogen released combines with carbon IV oxide to form glucose while the oxygen is released to the atmosphere. These processes take place via a series of complex mechanism and biochemical pathways to give the expected products.
