¬¬¬Biology Exam 4 Energy III – Cellular Respiration (Krebs Cycle and Electron Transport Chain) A. The Krebs Cycle a. Energy i. The net gain of 2 ATP and 2 NADH represents an effective transfer of 20 kcal of energy to ATP (about 10 kcal each) about 80 kcal of energy to NADH (about 40 kcal each)‚ for a total of about 100 kcal ii. Complete oxidation of glucose results in the release of 684 kcal of energy‚ significant energy still remaining in pyruvate b. Eukaryotes i. Pyruvate is transported

of electron acceptors including NAD+ • In the end‚ high-energy electrons from initial chemical bonds have lost much of their energy • Transferred to a final electron acceptor Type of Metabolisms • Generally speaking‚ the type of terminal (final) electron acceptor determines the type or metabolism. • Aerobic respiration – Final electron receptor is oxygen (O2) • Anaerobic respiration – Final electron acceptor is an inorganic molecule (not O2) • Fermentation – Final electron acceptor

physiological changes can occur. If the body temperature falls below 36ºC or goes above 40ºC this can cause disorientation‚ and a temperature above 42ºC can cause convulsions and permanent cell damage. We continuously produce heat as a by-product of metabolism. When energy use increases due to physical activity‚ or when our cells are more active metabolically‚ additional heat is generated. The heat produced by biochemical reactions is retained by water‚ which accounts for nearly two thirds of body weight

muscle soreness. It is caused by a reduction in blood flow to the muscle. This leads to an accumulation of the metabolic by-products of exercise hydrogen ions from lactic acid within the muscle tissue. Lactic acid is a normal by product of muscle metabolism‚ but it can irritate muscle and cause discomfort and soreness. These by-product also stimulates pain receptor‚ but the pain and soreness usually disappear when you stop exercising or shortly thereafter. On the other hand‚ muscle soreness felt

Composition Tables that show dairy products are rich sources of BCAAs and whey protein isolate is a leading source of leucine. The author cites several studies that give increasing evidence that BCAAs‚ specifically leucine‚ have a unique affect on metabolism that includes regulation of muscle protein synthesis and glucose homeostasis. The impact of BCAAs is proportional to availability and dietary intake. Layman DK. The role of leucine in weight loss diets and glucose homeostasis. Journal of Nutrition
