Answer: Two electrons and a hydrogen ion
Explanation: The light reactions use solar power to reduce NADP+ to NADPH by adding a pair of electrons along with a hydrogen nucleus, or H The light reactions also generate ATP by powering the addition of a phosphate group to ADP, a process called photophosphorylation.
They both have their own DNA and produce proteins and enzymes required for them to function
Most of the infrared radiation to the Earth is absorbed and transmitted towards the Earth's surface.
