Answer #1

d) NAD+

NADH ( Nicotene amide dinucleotide) is a cofathat iscis central to metabolism.NAD is called dinucleotid because it consists of two nucleotide join through phosphate groups.

NAD+ accepts a hydrogen ion and 2 electrons and reduced to NADH.NADH moves to electron transport chain and donate a pair of electrons( oxidized) to the first compound in the chain.

NADH function as an oxidative factor in eukaryotic cell.NADH play a key role in production of energy through redox reactions.NAD serves as a cofactor for dehydrogenase,reductases, hydroxylasesmaking it major carrier of Hydrogen and electron in ,major metabolic pathways such as glycolysis , tricarboxylic acid cycle,fatty acid synthesis,steroid synthesis etc.

In step 6 of the citric acid cycle, succinate + FAD → fumarate + FADH2. Which statements concerning this reaction are true? Refer to the figure shown. (Note that in redox reactions, the molecule that “causes” another to gain or lose electrons is referred to as the agent.) Select all that apply. This is not an oxidation/reduction reaction; that is, no electrons have moved. Fumarate is more oxidized than succinate. FAD is more reduced than FADH2. FAD is an oxidizing...
