B-vitamins mostly function in

Options

A. Hormones
B. Enzymes
C. Coenzymes
D. Digestive substances

Answer

**Step-by-Step Solution:**

1. **Understanding B-Vitamins**: B-vitamins are a group of water-soluble vitamins that play crucial roles in various bodily functions, particularly in metabolism.

2. **Role in Metabolism**: These vitamins are essential for cell metabolism, which includes the processes that convert food into energy and the synthesis of red blood cells (RBCs).

3. **Function as Coenzymes**: Each B-vitamin typically acts as a coenzyme. Coenzymes are organic molecules that bind to enzymes and help them catalyze biochemical reactions. This means that B-vitamins enhance the activity of enzymes, facilitating various metabolic processes.

4. **Eliminating Other Options**:
- **Hormones**: B-vitamins do not primarily function as hormones, which are signaling molecules that regulate physiological processes.
- **Digestive Substances**: They are not digestive substances either; rather, they assist in metabolic processes after digestion has occurred.

5. **Conclusion**: Therefore, the primary function of B-vitamins is as coenzymes, which are necessary for the proper functioning of enzymes involved in metabolism.

**Final Answer**: B-vitamins mostly function in **coenzymes**.
