The major biochemical function for B vitamins within the human body is as

  1. a. antioxidants
  2. b. precursors for enzyme cofactors
  3. c. regulators for allosteric enzymes
  4. d. no correct response

Interpretation Introduction

Interpretation: The major biochemical function for B Vitamins within the human body has to be identified.

Concept introduction: Among the nine water-soluble vitamins, one is vitamin C.  The other eight vitamins are collectively called B vitamins.  These eight vitamins are grouped together on the basis of their biochemical functions.  They serve as precursors for enzyme cofactors.

Explanation of Solution

Reason for correct option:

The active form for vitamins in the human body is enzyme cofactor form.  Vitamins are obtained from the food through the digestion of food and they are converted into the enzyme cofactor form.  B vitamins serve as precursors for enzyme cofactors...
