NADPH builds up in the STROMA of the chloroplasts during electron transport. In chloroplasts, NADP+ is reduced by the ferredoxin-NADP+ reductase.
Nicotinamide adenine dinucleotide phosphate (NADPH) is the reduced electron form of NADP+.
The NADPH coenzyme is generated during the last step of the electron transport chain of the light-dependent reactions of photosynthesis.
NADPH is used by plant cells as an electron donor in different reactions associated with dehydrogenase and reductase enzymes.

The correct answer is B.
Channels and pumps are transmembrane proteins that create hydrophilic tunnels across the membrane. This allows molecules to be diffused through them. The channels and pumps are highly selective and only allow the diffusion of specific molecules. The channel's structure blocks the contact of the molecule with the head and tail of the phospholipids that form the membrane. As we said, the channels and pumps are proteins, so they are formed by amino acids. Therefore, the molecules passing through channels and pumps, only come in contact with the amino acids.
This process is called diffusion

1. The position affects the temperature of the planet because of how far away it is from it from the sun
2. Mercury and Venus are very close to the sun so they are very hot and can't support any life.Earth is the most perfect place to support life because it has water and a proper atmosphere. Mars is very rocky and is a unique red colour. Jupiter is a gas planet and has a red dot. Saturn has rings made of ice and dust just like Uranus and Neptune is so cold and is definitely too cold for humans to live.
3.Asteroides and coments are a mass of rock and dust and ice and coments have a tail of light and may be also know as shooting stars
