Table 'Salt' is NaCl Sodium Chloride and is not a proton donor has it has no hydrogen to donate
Salt is a compound, it doesn't accept or receive electrons. Sodium accepts electrons and is in salt.
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
When an excited electron is passed to an electron acceptor in a photosystem, energy in sunlight is transformed to chemical energy.
Neither. Helium doesn't form compounds and is neither an electron donor nor an electron acceptor.
oxygen
ATP-synthase
No, oxygen is the final electron acceptor of the electron transport chain.
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
In aerobic respiration, the final electron acceptor is (usually) oxygen. Sometimes it can be sulfur or nitrogen in the absence of oxygen (as in extreme environments) in extremophiles.
When an excited electron is passed to an electron acceptor in a photosystem, energy in sunlight is transformed to chemical energy.
No. A base would be a proton acceptor. Salt is not a base.
Neither. Helium doesn't form compounds and is neither an electron donor nor an electron acceptor.
oxygen
No, chlamydia doesn't have a final electron acceptor. That is why it needs to live within the host cells
Lewis acid is an electron pair acceptor.
DPIP substitutes for electron acceptor
Oxygen
ATP-synthase
