Final answer:
Resting energy expenditure, or basal metabolic rate (BMR), makes up roughly 75% of an individual's total Energy Expenditure, which is primarily the energy required for basic bodily functions and thermoregulation at rest.
Step-by-step explanation:
Resting energy expenditure, also known as basal metabolic rate (BMR), accounts for a significant portion of an individual's total Energy Expenditure. BMR refers to the amount of energy, measured in calories, that a person needs to maintain basic bodily functions at rest. This includes processes like circulation, breathing, cell production, and nutrient processing. It is influenced by several factors, including age, gender, body weight, and muscle mass. Athletes, due to having more muscle mass which requires more energy, tend to have a higher BMR.
About 75% of the calories burned in a day are attributed to the body's basic functions represented by BMR. Therefore, when considering the options provided in the question, the closest approximate percentage of Energy Expenditure that accounts for resting energy expenditure is 70%, even though this exact figure is not listed among the options provided. The typical resting (BMR) plus thermoregulatory processes (the energy required for temperature control) contribute to approximately this percentage of total daily energy expenditure.
In summary, while the provided answer options do not include the correct percentage based on the information provided, it's important to note that the actual resting energy expenditure is approximately 75% of total Energy Expenditure, encompassing the energy required for basic bodily functions and thermoregulation.
