#1
Which hormone is primarily responsible for regulating fat metabolism?
Leptin
ExplanationLeptin primarily regulates fat metabolism by signaling satiety and influencing energy balance.
#2
What is the term for the condition characterized by an excess accumulation of body fat?
Obesity
ExplanationObesity is a condition characterized by the excess accumulation of body fat, often leading to health issues.
#3
What is the term for the process by which fat cells decrease in size?
Lipolysis
ExplanationLipolysis is the process by which fat cells decrease in size as stored fat is broken down into usable energy.
#4
Which of the following hormones inhibits appetite and can lead to decreased fat storage?
Leptin
ExplanationLeptin inhibits appetite and can lead to decreased fat storage, playing a role in energy balance.
#5
What is the primary source of energy for adipose tissue?
Fatty acids
ExplanationFatty acids are the primary source of energy for adipose tissue, released through lipolysis for cellular use.
#6
Which of the following statements about brown fat is true?
It helps generate body heat
ExplanationBrown fat contributes to thermogenesis, generating body heat to help regulate temperature.
#7
What is the term for the process by which fat cells increase in number?
Adipogenesis
ExplanationAdipogenesis is the process of fat cell formation, leading to an increase in their number.
#8
Which hormone stimulates appetite and can lead to increased fat storage?
Ghrelin
ExplanationGhrelin stimulates appetite and promotes fat storage, influencing hunger and energy balance.
#9
What is the term for the process by which stored fat is broken down into fatty acids and glycerol?
Lipolysis
ExplanationLipolysis is the breakdown of stored fat into fatty acids and glycerol, releasing energy for cellular use.
#10
Which organ primarily regulates fat metabolism?
Liver
ExplanationThe liver plays a key role in regulating fat metabolism, controlling the synthesis and breakdown of fats.
#11
What is the primary function of adipose tissue?
All of the above
ExplanationAdipose tissue functions include energy storage, insulation, and hormone production, contributing to overall metabolic balance.
#12
What is the main difference between subcutaneous fat and visceral fat?
Location
ExplanationThe main difference between subcutaneous and visceral fat is their location in the body.
#13
Which of the following factors can contribute to fat accumulation?
Chronic stress
ExplanationChronic stress can contribute to fat accumulation through hormonal changes and increased calorie intake.
#14
Which of the following is NOT a function of adipose tissue?
Blood clotting
ExplanationAdipose tissue does not have a role in blood clotting; its functions include energy storage, insulation, and hormone production.
#15
Which of the following statements about fat cells is true?
Fat cells can divide and increase in number throughout life.
ExplanationFat cells can divide and increase in number throughout life, contributing to changes in body fat.
