Basal Metabolic Rate is influenced by

Options

A. GH
B. Glucagon
C. thyroxine
D. ADH

Answer

### Step-by-Step Solution:

1. **Understanding Basal Metabolic Rate (BMR)**:
- Basal Metabolic Rate is the rate at which your body expends energy at rest to maintain vital functions such as breathing, circulation, and cell production.

2. **Identifying Influencing Factors**:
- BMR can be influenced by several factors, including age, sex, body composition, and hormonal levels.

3. **Role of Thyroxin**:
- Thyroxin, a hormone produced by the thyroid gland, plays a significant role in regulating metabolism. It increases the metabolic rate by stimulating metabolic activities in various tissues.

4. **Mechanism of Action**:
- Thyroxin enhances oxygen consumption and promotes the oxidation of glucose in metabolically active tissues. This increase in glucose oxidation leads to a higher metabolic rate.

5. **Conclusion**:
- Therefore, the primary hormone influencing Basal Metabolic Rate is thyroxin. Other hormones like glucagon and ADH do not have a direct impact on BMR.

6. **Final Answer**:
- The basal metabolic rate is influenced by thyroxin.
