The right answer is B) NADH and FADH2.

NADH, FADH2 are molecules involved in the Krebs cycle, they carry electrons and H + protons.

NAD is involved in metabolism as an electron carrier in oxidation-reduction reactions, NAD + as an oxidant and NADH as a reducing agent.

Flavin adenine dinucleotide (FAD) is an oxidation-reduction cofactor derived from riboflavin (vitamin B2). It is associated with the enzymes of the class of oxido-reductases to which it is linked by a covalent bond: it is a prosthetic group.

The redox couple is: FAD ==> FADH.

Nicotinic receptors a. are found at neuroeffector junctions of the parasympathetic nervous system. b. respond to epinephrine. c.
Verizon [17]

Answer:

Option C, open chemically gated sodium ion channels.

Explanation:

The nicotinic receptors are present on the muscle cell membrane. These receptors belong to the class of cholinergic receptor which binds to the acetylcholine and opens the gated channel to allow transfusion of cation through it. These actions of the receptors are stimulated by the neurotransmitter. Nicotinic receptors are very fast at acting and hence are more prevalent at the neuromuscular junction.

Hence, option  C is correct
