The roles played by four key hormones in the body, namely Insulin, Adrenaline, Cortisol and Glucagon, become interconnected actions to insure metabolic regulation occurs in the human body. All four hormones are not just responsible for their own specific ‘task’ and are involved in a range of interconnected actions. The three key areas of paramount importance in metabolic regulation in the human body are glucose storage and mobilisation, protein storage and mobilisation and fat storage and mobilisation. The hormone insulin stimulates anabolic and inhibits catabolic process involved in carbohydrate, fat and protein metabolism in the human body. The hormones Adrenaline, Cortisol and Glucagon stimulate catabolic processes involved in carbohydrate, fat and protein metabolism in the human body (Newsholme, …show more content…

The maintenance of the concentration of blood glucose in the human body is achieved by a balance between glucose utilisation rates and glucose supply. Changes in either of these can result in detrimental effects on the human body.
Insulin is the key hormone of carbohydrate metabolism (Geser,1976).Insulin and glucagon both regulate blood glucose, and both of the mentioned hormones portray opposite actions of one another. For example, insulin stores glucose, and glucagon takes it out of storage. In addition adrenaline effects the storage and mobilisation of glucose.
The hormone glucagon is released in response to a decrease in blood glucose concentration and this is quiet opposite to the hormone insulin, which is released in response to an increase in blood glucose concentration. Insulin and glucagon may portray opposite actions and are counter regulatory but the purpose of both hormones is the same, in that they are both working to maintain adequate levels of blood glucose concentration in the human

The supply of glucose to the brain and immune system is important as competitors constantly rely on instantaneous decision making to ensure they make effective strategic moves. Glucagon is the hormone which ultimately increases blood glucose concentration by breaking down stored glycogen in muscle and fat cells, increasing the breakdown of fats and increasing liver glucose production. Each of these effects lead to an increased amount of glucose present in the bloodstream, meaning more energy for body cells. When the level of glucose in the bloodstream drops, more glucose is required in order to provide ATP for energy. The secretion of insulin by beta cells is inhibited

Diabetes is a metabolic disease where the person has high blood sugar. This is either because the body does not produce insulin properly, the cells do not respond to the insulin, or both. There are three types of diabetes. Type 1 Diabetes is where the body does not produce insulin.

It is released in moments of stressed, whether emotionally, physically, or environmentally. Cortisol plays an important role in regulating our body metabolism in breaking down protein to amino acids, which is then moved to liver. The liver then converts these excess amino acids to glucose.

Hurji Burka Human Anatomy and Physiology I 1a. A specific example of homeostatic regulation is glucose. Glucose is classified as a sugar in the human body. It is important for glucose levels to maintain homeostasis to avoid diseases like diabetes. Three different regulatory components for glucose that contribute to maintaining homeostasis include the control center, receptors, and effectors.

Reginald Garrett and Charles Grisham in their book "Biochemistry." The pancreas responds to high levels of blood sugar by releasing the hormone insulin, which signals cells to take up sugar from the blood. Sugar overdoses lead to pancreatic overreactions, which causes cells to take up far too much blood sugar. As such, a sugar overdose results in very high blood sugar, shortly followed by very low blood sugar, which causes fatigue, nausea, weakness and hunger.

Diabetes is an illness caused high blood sugar and metabolic disease. Hyperglycemia is due to problems production or action in insulin of biological damage caused, or both. People who have diabetes for a long time may experience damage to many parts of the body with high blood sugar, leading to a variety of organizations, particularly chronic damage to the eyes, kidneys, heart, blood vessels, nerves, and dysfunction. In general, people with Type 1 diabetes have a lack of insulin while people who have Type 2 diabetes have too little insulin or cannot use insulin effectively.

Our bodies take in the glucose and turn it into energy we can then use. When we let glucose in, we are raising our insulin and glucose levels. Insulin is the hormone in people’s bodies that grants glucose access into our bloodstreams. However, insulin keeps our blood levels from raising or lowering, and it stores the fat to use for energy later on. Unfortunately, people have no control over the insulin function, though they do have control over the types of food they eat that contain certain amounts of glucose.

If an individual is stressed, cortisol levels rise and release more glucose. This is done so that the body has more fuel to “fight or run” during the moments of high stress. However, having too much cortisol can mean that the body has too much glucose floating around. If the glucose does not get used, it is then stores as excess fat in the body, which in turn lead to overweight and obesity as it continues. In the same study, researchers found that obese individuals that have a BMI higher than 30% of the suggested healthy weight also have the highest cortisol levels.

Diabetes is a disease in which the body does not produce enough insulin or the cells cannot effectively use insulin. Most of what we eat is broken down into glucose. The glucose makes its way into the blood stream and the cell use it for energy and growth. If there is no insulin the glucose cannot enter the cells and it stays therer and in the blood and bulid to higher and higer levels. And at this time a person will develop the disease.

With my family having a history of this disease we take it very seriously and don’t joke around with it. Diabetes is a group of diseases that affect how your body uses blood sugar (glucose). Glucose is vital to your health because it’s an important source of energy for the calls that make up your muscles and tissues. It’s also your brain’s main source of fuel. There are different types of diabetes: type 1, type 2, and even gestational diabetes.

The adrenals are known for making the hormone adrenaline but also, they make the corticosteroids which affect your metabolism and sexual function. The pancreas is part of the the digestive system and the endocrine system. It makes the hormones insulin and glucagon. These help ensure you have the right amount of sugar in your bloodstream and your cells. If you don 't make any insulin, which is the case for people with type one diabetes, your blood sugar levels can get dangerously high and if the body makes some insulin but not enough, that is type two diabetes.
