Document Summary
Glucose energy metabolism: glycolysis happens in cytoplasm some atp is produced. Nadh is produced and is carrier of electron: pyruvate acetate coa. Nadh: tca cycle (tricarboxylic acid cycle/kreb"s cycle) Acetyl coa (2-c) + oxaloacetate ( 4-c; glucose) Produces some atp, produce most carbon dioxide (co2) & nadh: electron transport chain. If you over consume stores as fat (lipogenesis) Fasting state occurs 4 + hours after eating a meal causes decrease in insulin & increase in glucagon production the increase of glucagon has no effect on the skeletal muscle but the lack of insulin does. During fasting state: increase of glucagon affects liver glycogenolysis & gluconeogenesis occurs. Metabolic process; lipolysis occurs & there"s usage of fatty as fuel. When in a fasting state, the main source of energy is fat. When the insulin levels are low it signals to the adipose cells to open & triglyceride is released causing the cell to shrink.
