However‚ organs such as the brain‚ liver and kidney do not just rely on carbohydrates to receive their energy. A process known as gluconeogenesis takes place in these organs when the body goes into a fasting period‚ intensive exercise or when there is a low-carbohydrate intake. The process of gluconeogenesis utilizes certain non-carbohydrate carbon substrates to produce glucose for energy.

The five hormone’s that play a role in regulation of glucose metabolism are Insulin‚ Glucagon‚ Epinephrine‚ norepinephrine‚ and cortisol. Insulin is located in the pancreas and the action of insulin is remarkable and also not as complex as most people would think. Glucose is taken up by a muscle that is at rest‚ which in turn regulates blood glucose concentration. This process isn’t difficult to understand because it isn’t as many parts to the process. Glucagon also finds itself located in the pancreas

Homeostasis is the maintenance of the relatively constant physiological state of the internal environment‚ the biological term meaning ‘same state’‚ is the control of the body’s internal conditions despite fluctuations in the external environment. Blood glucose refers to the sugar that is transported through the bloodstream to supply energy to all the cells in our bodies. Cells in the body need glucose for respiration through mitochondria‚ which produces ATP- the energy source for all processes of

The liver is the largest organ in the entire‚ normal human body. It weighs anywhere from 2.5 to 3.3 pounds. With its large size it is also a very resilient organ. Up to 3/4 of its cells can be removed before is ceases to function. It is red-brown organ roughly shaped like a cone. The liver is located in the upper right abdominal cavity immediately beneath the diaphragm. Without the liver‚ we could not survive. It serves as the body’s chemical factory and it regulates the levels of most of the main

Metabolisms are all the chemical reactions that the living cells and organisms use to maintain life. It also divides into two categories: Catabolism – that breakdown the molecules to obtain energy and Anabolism – that creates all of the compounds that the cells need to function. Nutrition is an important part of the availability of nutrients that utilized in the reactions that either synthesize or catabolize the material that is employed by the cells to produce power. This power is a requirement
