Question

multiple choice question
the b vitamins function as which of the following?
minerals
nitrogen source
energy source
coenzymes

Explanation:

B vitamins (like B1, B2, B3, etc.) function as coenzymes. Coenzymes are non - protein molecules that assist enzymes in catalyzing biochemical reactions. Minerals are inorganic elements (e.g., iron, calcium), B vitamins aren't minerals. Nitrogen source is for compounds like proteins/amino acids, not B vitamins. B vitamins don't directly act as energy sources (energy comes from carbs/fats/proteins, though B vitamins help in energy - related reactions). So the correct option is the one with "Coenzymes".

Answer:

Coenzymes (the option labeled "Coenzymes")
