Which of the following is true regarding the mechanisms by which energy balance is regulated?

a. lower levels of ghrelin will increase satiety

b. gastric distention is not a significant factor regulating satiation

c. as fat stores increase, adipose tissue produces less leptin

d. leptin plays a significant role in the process of short-term satiation

Expert Solution

With respect to energy balance, lowere levels o ghrelin will increase satiety. This Ghrelin peptide of 28 amino acids, mostly secreted in the gastric fundus mucosa. In humans, there is preprandial rise and postprandial fall in plasma ghrelin levels , which strongly suggests that the peptide plays a physiological role in meal initiation. Thus in human body, ghrelin induces a positive energy balance, an increased adiposity gain, as wells as increase in caloric context.
