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.

According to the gate control theory of pain, the structure that is the likely location of the gate is the substantia gelatinous.
<h3>
What is substantia gelatinous?</h3>
- A group of cells called the substance gelatinosa can be found in the spinal cord's gray matter (dorsal horns).
- It receives direct input from the dorsal (sensory) nerve roots, particularly those fibers from pain and thermoreceptors, and is present at all levels of the cord.
- The spinal cord has a system that permits pain signals to be amplified in the brain before being processed at the spinal cord itself, or attenuated there, in accordance with the Gate Control Theory of Pain.
- The "gate" is the device that either permits or forbids the transmission of pain signals.
- To feel intense pain if the gates are more open since many more pain signals will flow through to the brain.
- The likelihood that you will feel less discomfort increases as the gates are more tightly shut.
