BIO 360 Chapter Notes - Chapter 14: Gluconeogenesis, Oxaloacetic Acid, Metabolic Pathway
Document Summary
Glycolysis occurs mainly in the muscle + brain. 2 pyruvate + 4 atp -12 gtp -12 nadh -121-1+41-120 glucose + 4 adp -12gbp-16 pi +2 nad. End product of one is the starting compound of the other. Reversible reactions both pathways of glucose when glycogen stores are depleted. V1 goitrous exercise glucose from amino acids t. no fatty acids) Physiologically necessary : brain nervous system , and red blood cells. Metabolic pathway ; results in generation of glucose from certain. L generate atp only from non - carbohydrate carbon substrates. Process occurs during periods of fasting , starvation , low - carbohydrate diets / intense exercise. Mammals gluconeogenesis is believed to be restricted to the liver the kidney , the intestine , + muscle . New evidence suggests that it occurs in astrocytes of the brain. Path from pyruvate to phosphoenolpyruvate leads through oxaloacetate.
