Frequent question: Which one of the following hormones stimulates the breakdown of glycogen in the liver into glucose *?

Term Definition
glucagon a hormone that tells cells in your liver and muscles to convert glycogen into glucose and release it into your blood so your cells can use it for energy
pancreas an organ in your abdomen that makes and releases insulin and glucagon

Which hormone stimulates the breakdown of glycogen in the liver into glucose?

Glucagon’s role in the body is to prevent blood glucose levels dropping too low. To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream. This process is called glycogenolysis.

Which of the following hormones stimulates the breakdown of glycogen into glucose in the liver a glucagon B thyroxine C prolactin D follicle stimulating hormone?

Insulin lowers blood glucose levels by enhancing the rate of glucose uptake and utilization by target cells, which use glucose for ATP production. It also stimulates the liver to convert glucose to glycogen, which is then stored by cells for later use.

Which of the following hormones stimulates breakdown of glycogen and increase blood glucose concentration?

Epinephrine or Adrenaline:- It is secreted by adrenal medulla and performs two functions: It stimulates glycogenolysis in the liver and muscle by stimulating the phosphorylase activity. In muscle, glycogenolysis occurs with formation of lactate.

Which hormone causes the creation of glycogen in the liver?

Glucagon causes the liver to engage in glycogenolysis: converting stored glycogen into glucose, which is released into the bloodstream. High blood-glucose levels, on the other hand, stimulate the release of insulin. Insulin allows glucose to be taken up and used by insulin-dependent tissues.

Which hormone stimulates glycogenolysis in liver?

Glucagon promotes glycogenolysis in liver cells, its primary target with respect to raising circulating glucose levels. This effect appears to be mediated through stimulation of adenylyl cyclase and production of intracellular cAMP and activation of phosphorylase-a.

What hormone decreases blood sugar?

Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon.

Which gland is also called the master gland?

The pituitary gland is sometimes called the “master” gland of the endocrine system because it controls the functions of many of the other endocrine glands.

When is glycogen used?

When the body needs a quick boost of energy or when the body isn’t getting glucose from food, glycogen is broken down to release glucose into the bloodstream to be used as fuel for the cells.

Which of the following hormones stimulates Glycogenesis?

Pancreatic insulin: Insulin is the main regulatory hormone produced and secreted by the pancreatic beta cells. It stimulates the uptake of glucose and the movement of glucose from blood to cells for energy production. Insulin also stimulates glycogenesis, inhibits glycogenolysis, and regulates protein synthesis.

Which part of the body controls hormones?

The pituitary gland is a small pea-sized gland that plays a major role in regulating vital body functions and general wellbeing. It is referred to as the body’s ‘master gland’ because it controls the activity of most other hormone-secreting glands.

Is the process of making glycogen?

Glycogenesis is the process of glycogen synthesis, in which glucose molecules are added to chains of glycogen for storage. This process is activated during rest periods following the Cori cycle, in the liver, and also activated by insulin in response to high glucose levels.

Which organ monitors rise in blood sugar?

Your pancreas constantly monitors and controls your blood sugar levels using two hormones. The best known of these is insulin. When your blood sugar levels rise after a meal your pancreas releases insulin. Insulin allows glucose to be taken into the cells of your body where it is used in cellular respiration.

What is the function of liver glycogen degradation?

In the liver, glycogen synthesis and degradation are regulated to maintain blood-glucose levels as required to meet the needs of the organism as a whole. In contrast, in muscle, these processes are regulated to meet the energy needs of the muscle itself.

What organ controls your blood sugar?

Insulin is the main regulator of sugar in the bloodstream.

Beta cells are found in the pancreas, which is an organ behind the stomach. Insulin levels in the blood stream are carefully calibrated to keep the blood glucose just right.
