Question

Insulin is released from _____, causing blood sugar to ________ because it binds to ______, allowing ________ to be taken in by cells. Alternately, when the body needs _______, blood sugar is _______ and we feel hungry. In this case Glucagon is released from __________ resulting in _________ being broken down into ________, increasing ________ in the blood. This is a balancing, antagonistic, negative feedback loop that maintains sugar balance in the blood and allows energy when needed.)

Answer 1

Insulin is released from beta cells in the pancreas, causing blood sugar to decrease because it binds to receptors, allowing glucose to be taken in by cells. Alternately, when the body needs energy, blood sugar is increased and we feel hungry. In this case, glucagon is released from alpha cells in the pancreas resulting in glycogen being broken down into glucose, increasing blood sugar in the blood.

Step-by-step explanation:

Insulin, released from beta cells, decreases blood sugar and allows glucose uptake, while glucagon from alpha cells increases blood sugar during energy demand, exemplifying a negative feedback loop.This is a balancing, antagonistic, negative feedback loop that maintains sugar balance in the blood and allows energy when needed.

The effects of insulin and glucagon on blood glucose levels are vital for homeostasis and can be disrupted in conditions like diabetes mellitus. These hormones' action reflects the essential functions of regulating blood glucose levels and maintaining the body's energy balance.
