It is the active form of vitamin B6. It acts as a coenzyme in enzymatic reactions, e.g. transamination and deamination reactions.
the general term is cofactor, but more specifically, if the cofactor is an organic molecule, it is called a coenzyme

No. Acetic acid (the 'active' ingredient in vinegar) is structurally, physically and chemically very different to vitamin C (an isomer of ascorbic acid).
Any of a group of disturbances of porphyrin metabolism characterized by excess pophyrins (various biologically active compounds with a distinct structure) in the urine and by extreme sensitivity to light.
Pantothenic acid is converted into its active form Coenzyme A.

B vitamins and especially vitamin B6 are most commonly associated with enhancing metabolism. There are also many others that can aid in increasing metabolism such as vitamin C, and Green Tea. These are just a few that are commonly referred to when speaking of metabolism. Always remain skeptical of claims made about increasing metabolism. Some substances have limited evidence to suggest they actually increase metabolism. Vitamin C has been shown to increase fat-burning, but only amongst overweight individuals who were Vitamin C deficient. Use Google Scholar to check and see just whether a supplement has any evidence for increasing metabolism in normal people- and just how much.

The active forms of Riboflavin (B2) are FAD and FMN.The active form of Pantothenic acid (B5) is Coenzyme A.
Isoniazid is a first line anti-tubercular drug which is used in treatment of tuberculosis.Pyridoxine is the naturally occurring form of vitamin B6. Following absorption from the gastrointestinal tract, it is converted in the liver to a coenzyme, pyridoxal phosphate, that is involved in many metabolic processes. Isoniazid interferes competitively with pyridoxine metabolism by inhibiting the formation of the active form of the vitamin, and hence often results in peripheral neuropathy.Hence, to prevent peripheral neuropathy, pyridoxine 10mg/day is given prophylactically to patients along with anti-tubercular treatment.Patients with evidence of vitamin B6 deficiency may require doses upto 50mg/day.
No. No ref, but 2:1 ratio is bandied about.
The skin, liver, and kidneys participate in synthesizing the active form of vitamin D.
NOVA NET ANSWER-------- calcium and phosphorus Vitamin D is absorbed in the gut, then travels to the skin, where it is converted by UV rays (from the sun) to Vitamin D3. From here, it is converted in the kidneys to calcitriol (or 1,25-dihydroxycholecalciferol), which is the biologically active form of the Vitamin. From here, it goes back to the intestine and assists in absorption of Calcium from the diet.
The answer is vitamin D. In presence of ultraviolet rays cholesterol is converted to vitamin D in the skin. One hydrogen atom is attached to it in liver and second in kidney to form active form of vitamin D.
