Thermogenesis makes a(n) ______ contribution to overall energy expenditure.Multiple choice question.moderate to averageextremely largefairly smallfairly large

To determine the correct choice for the contribution of thermogenesis to overall energy expenditure, we can analyze each option:

1. Moderate to average: This suggests a middle ground, which does not specifically indicate the impact of thermogenesis.

2. Extremely large: This implies that thermogenesis plays a very significant role, which is typically not the case.

3. Fairly small: This option indicates a limited contribution of thermogenesis, aligning with common understanding that thermogenesis contributes a smaller portion to overall energy expenditure.

4. Fairly large: This suggests a substantial contribution, which is also not consistent with most evidence.

Considering the general consensus in metabolic studies, thermogenesis, while important, usually accounts for a smaller fraction of total energy expenditure in comparison to basal metabolic rate (BMR) and physical activity.

Final Answer

Thermogenesis makes a(n) fairly small contribution to overall energy expenditure.
