(oxygen, electron transport chain, chemiosmosis, NADPH)
Vaselesa [24]

Hai there :3 I'm planning to study chemical engineering.

Question related to Biochemistry (Photosynthesis & Cellular Respiration)

1. Chemiosmosis.  In the process of chemiosmosis, specific enzymes (such as ATP synthase) create ATP. Hydrogen ions go from a higher proton concentration to a lower one, which is why it's called chemio"osmosis"

2. Electron Transport Chain (ETC). The name says it all. Simply explained, electrons are transported and transferred in the mitochondrial membrane.

3. Oxygen. O2, the diatomic molecule, is essential in respiration. In the final stage of respiration, at the near end of the electron transport chain, oxygen accepts protons to become water. Cells use O2 during oxidative phosphorylation.

4. NADPH. I remember learning what this acronym means by heart. Nicotinamide Adenine Dinucleotide Phosphate Hydrogen. NADPH is essential in photosynthesis as a typical coenzyme in the reduction of chemical reactions.
