(oxygen, electron transport chain, chemiosmosis, nadph) atp synthesis in both chloroplasts and mitochondria involves the process called in both cellular respiration and photosynthesis, a(n) built into a membrane pumps h+ across the membrane as electrons are passed from one electron carrier to the next in a series of redox reactions in respiration, the electrons come from the oxidation of organic molecules, and the final electron acceptor. in photosynthesis, the electrons come from water and end up in

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.
