ATP is adenosine triphosphate and is like a charged battery ADP is called adenosine diphosphate and is like an uncharged battery

The 3 Stages of Aerobic Cellular Respiration Glycolysis 2) Kreb’s Cycle 3) Electron Transport Chain

Glycolysis Name means “Glucose- splitting Happens in the cytoplasm Starts with glucose and makes 2 pyruvic acid molecules Uses 2 ATPs but produces 4 ATP---- 2 net ATPs produced!!! Also makes NADH (high energy molecule)

Intermediate Reaction Before the Kreb Cycle, the pyruvate made in glycolysis is converted to Acetyl CoA

Kreb’s Cycle (AKA Citric Acid Cycle) Occurs in the mitochondria! Reactants: Products: ADP+ P ATP NAD NADH- goes to ETC FAD FADH2-goes to ETC Oxygen CO2- breathed out

Electron Transport Chain (ETC)

Electron Transport Chain (ETC) Occurs in the mitochondria! Reactants: Products: ADP+ P 34 ATP!!! NADH NAD FADH2 FADH Oxygen

Stage ATP Produced Glycolysis 2 Kreb’s Cycle Electron Transport Chain 34

Releasing Energy w/out Oxygen Anaerobic Respiration Starts with Glycolysis! After glycolysis, fermentation occurs Two Types Lactic Acid Fermentation Alcoholic Fermentation April 4, 2019

Lactic Acid Fermentation bacteria, plants and most animals Starts with glycolysis! After glycolysis 2 pyruvic acid changed to lactic acid Sometimes happens in your muscles, cramps-----Exercise April 4, 2019

Alcoholic Fermentation Bacteria and fungi (yeast) Ethyl alcohol and carbon dioxide are the end products Process used to form beer, wine, and other alcoholic beverages Also used to raise dough, bread April 4, 2019
