Question

In the first half of the Citric acid cycle, ____________ is oxidized, yielding a pair of electrons that reduce a molecule of NAD to NADH. Succinate is oxidized to fumarate using ____________ as the electron acceptor. A 2-carbon group from ____________ enters the cycle. A second oxidation produces ____________ and 2 electrons. Malate is oxidized, yielding a 4-carbon molecule of ____________ and two electrons.

Answer 1

Answer:

Pyruvate, FAD, Acetyl CoA, Fumarate, Oxaloacetate

Explanation:

In the first half of the citric acid cycle pyruvate is oxidized,yielding a pair of electrons that reduce a molecule of NAD to NADH .Succinate is oxidized to fumarate using FAD as electron acceptor.A 2 carbon group from acetyl CoA enters the cycle.A second oxidation produces fumarate and 2 electrons.Malate is oxidized yielding a 4 carbon molecule of oxaloacetate and two electrons.
