Question

what two molecules carry high - energy electrons to the electron transport chain?
e - & atp synthase
h+ & fadh2
h+ & nadh
none of these options
nadh & fadh2
atp & adp
clear my selection

Explanation:

In cellular respiration's electron - transport chain, NADH (nicotinamide adenine dinucleotide) and FADH2 (flavin adenine dinucleotide) are the molecules that carry high - energy electrons. These molecules are produced during glycolysis, the citric acid cycle, and other metabolic processes and donate their electrons to the electron - transport chain, which uses the energy from the electrons to pump protons across the inner mitochondrial membrane, creating a proton gradient that is used to produce ATP.

Answer:

E. NADH & FADH2
