Question

question 10 of 20 electron carrier molecules transfer electrons between metabolic pathways. choose the electron carriers that transfer electrons from glycolysis to the electron transport chain and from the citric acid cycle to the electron transport chain. one of the molecules will be placed more than once. more than one molecule may act as an electron carrier in these two pathways.

Explanation:

In cellular respiration, NADH is produced during glycolysis and the citric - acid cycle and donates electrons to the electron - transport chain. FADH₂ is also produced in the citric - acid cycle and transfers electrons to the electron - transport chain. NAD⁺ and FAD are the oxidized forms and are not the electron carriers that directly transfer electrons to the electron - transport chain from these pathways.

Answer:

NADH, FADH₂
