What is the term for the number of calories required to maintain basic bodily functions at rest?

1. Accelerated Metabolic Rate

2. Catabolic Rate

3. Basal Metabolic Rate

4. Anabolic Rate

The correct answer is: Basal Metabolic Rate

The term that refers to the number of calories required to maintain basic bodily functions at rest is known as the Basal Metabolic Rate (BMR). BMR represents the minimum amount of energy the body needs to perform vital functions while at rest, such as breathing, circulation, cell production, nutrient processing, and temperature regulation. This measurement is crucial for understanding an individual's metabolism and energy needs, as it provides the baseline for calorie requirements in various situations, such as weight loss, gain, or maintenance. In contrast, the other terms relate to different metabolic processes or states. The Accelerated Metabolic Rate typically refers to an increased rate of metabolism, often due to exercise or stress, rather than resting conditions. The Catabolic Rate pertains to the breakdown of molecules to obtain energy, while the Anabolic Rate is concerned with the building up of molecules for growth and repair. Therefore, BMR is specifically focused on the energy expenditure at rest, making it the correct choice for the question posed.
