After eating a large meal of pasta, an individual's blood sugar levels are elevated. in response to this, the pancreas secretes a hormone called insulin, which acts to lower blood sugar levels. once the blood sugar levels drop to the normal level, the pancreas stops secreting insulin. this is an example of
a) acid-base imbalance
b) reactions between carbon monoxide and acids
c) a positive feedback loop
d) a negative feedback loop
e) energy being made into proteins

d) A negative feedback loop

Explanation:

A negative feedback loop counteracts the deviation from homeostasis by generating a required response. The function of the insulin hormone is to lower down the blood glucose level when it raises above the normal range. Insulin triggers the uptake of glucose from the blood by cells. It specifically triggers muscle and liver cells to take up glucose from the blood.

Once the blood glucose level is restored to the normal value, the secretion of insulin stops. Here, a change in normal body condition (raised blood glucose level) was counteracted by the secretion of insulin hormone to restore the homeostasis of blood sugar levels.
