fumarate fadh₂ fad succinate

Explanation:

Step1: Understand oxidation - reduction concept

Oxidation is loss of hydrogen or gain of oxygen; reduction is gain of hydrogen or loss of oxygen.

Step2: Analyze the reaction

Succinate loses two hydrogens to form fumarate and FAD gains two hydrogens to form FADH₂.

Step3: Determine oxidized and reduced species

The species that loses hydrogen is oxidized and the one that gains hydrogen is reduced.

Answer:

Oxidized: succinate
Reduced: FAD
