Summary Introduction
Introduction:
BMR or basal metabolic rate is defined as the rate of expanded energy per unit time by an endothermic animal at the state of rest. It shows the energy amount per unit time, which is used by a person for the proper functioning of the body at rest. Factors affecting BMR include body size, weight, muscle mass, body temperature, and gender. Thyroid hormone is responsible for regulation and maintenance of BMR.

- A number of hormones in the body are responsible for controlling blood glucose levels. Some examples include insulin, glucagon, adrenaline, and cortisol.Select the FOUR numbers below that correctly show the pathway for insulin. Insulin is secreted when blood sugar levels are high. Insulin is secreted when blood sugar levels are low. Insulin is released from the beta cells of the pancreas. Insulin is released from the alpha cells of the pancreas. Insulin makes cells more permeable to glucose. Insulin makes cells less permeable to glucose. Glycogen is taken up and converted to glucose. Glucose is taken up and converted to glycogen.arrow_forwardThe glycemic index is a ranking scale used as an indicator of how high and how fast your blood sugar (blood glucose levels) will rise and then elicit an insulin response.
