Glycolysis “Splitting of glucose” into two 3-carbon molecules TCA Cycle (Citric acid cycle, Krebs Cycle) Some ATP synthesis Some NADH synthesis (takes up electrons) CO 2 production Some ATP synthesis Some NADH synthesis (takes up electrons) Electron Transport (Oxidative Phosphorylation) NADH gives up electrons O 2 converted to H 2 O Lots of ATP synthesis!!!!! Cellular Respiration
Brown Fat and Heat Generation Brown fat cells
Uncoupling Electron Transport from ATP SynthesisUncoupling Electron Transport from ATP Synthesis Inner Mitochondrial Membrane
Regulation of Blood Glucose Hormone: Insulin Insulin is produced in the pancreas Insulin stimulates: Glucose uptake Glycogen synthesis Glycolysis/TCA cycle
Insulin Hormone Made in the pancreas Response to high glucose
