Multiple Choice
Which of the following statements is true about storage body fat in relation to homeostasis?
A
Storage body fat is the main source of glucose for the brain.
B
Storage body fat is not involved in the regulation of body temperature.
C
Storage body fat is primarily used for immediate energy needs during exercise.
D
Storage body fat helps maintain energy balance by storing excess calories.
Verified step by step guidance1
Understand the role of storage body fat in the body: Storage body fat serves as an energy reserve, storing excess calories that can be used when the body requires energy.
Consider the relationship between storage body fat and homeostasis: Homeostasis involves maintaining a stable internal environment, and storage body fat contributes to this by regulating energy balance.
Evaluate the statement about glucose: The brain primarily relies on glucose from carbohydrates, not storage body fat, for its energy needs.
Assess the statement about body temperature: Storage body fat does play a role in insulating the body and helping to regulate temperature, contrary to the statement.
Analyze the statement about energy use during exercise: While some fat may be used during prolonged exercise, immediate energy needs are typically met by carbohydrates, not storage body fat.
