body. This is the process whereby the body uses hormones to keeps the glucose levels in the blood at a stable level to ensure the body’s optimum function. Blood sugar levels are determined by the amount of carbohydrates and sugars we ingest. When we eat the food travels into the stomach‚ and digestion begins. The digestive system works with nerve impulses and hormones to secrete acids into the stomach. The body requires glucose to create ATP. Because the amount of ATP that is needed fluctuates‚ the

researchers in the 1940s and 1950s suggested that the brain regulates food intake in order to maintain a blood-glucose set point. The idea was that people become hungry when their blood-glucose levels drop significantly below their set point and that they become satisfied after eating‚ when their blood-glucose levels return to that set point. This theory seemed logical because glucose is the brain’s primary fuel (Pinel‚ 2000). The earliest investigation of the general effects of food deprivation

1. Candy bars are well known to supply large amounts of energy for metabolism. With all this energy trapped inside‚ how can the candy bar sit still on the shelf in the grocery store? Indeed‚ candy bars have a significant amount of carbohydrates (mostly simple‚ such as sugar) in their composition. The energy stored within these carbohydrates is chemical potential energy‚ and cannot actually be released or converted into usable chemical energy until it is eaten and taken up into the body‚ where various

the mitochondria. Aerobic respiration provides a lot of energy needed per molecule of glucose (the level of ATP produced can be as high as 38 ATP molecules per 1 molecule of glucose. When the body is exercising intensely respiration happens faster and the muscles need more oxygen. Anerobic respiration uses a reaction of glucose and water to make energy it creates by-products of water and carbon dioxide (glucose + oxygen → carbon dioxide + water (+ ATP or C6H12O6 + 6O2 → 6CO2 + 6H2O) There will come

Composition of Blood Blood contains a nonliving fluid matrix (plasma) in which living cells (formed elements) are suspended. Blood contains 55% plasma and 45% formed elements. Plasma is over 90% water. It also contains electrolytes (salts)‚ plasma proteins‚ and substances transported by blood (i.e. nutrients‚ hormones‚ etc.). The three types of formed elements are erythrocytes (RBCs)‚ leukocytes (WBCs)‚ and platelets FUNCTIONS OF BLOOD functions of the blood are: to transport oxygen away
