Biology I Cellular Respiration

Cellular respiration the process in which glucose is broken down to produce ATP (energy) Performed by ALL cells (plant, animal, bacteria) Two pathways Aerobic Respiration Anaerobic Respiration Both begin with Glycolysis

Cellular respiration pathways Cellular Respiration Glycolysis Oxygen present Oxygen absent Aerobic Respiration Anaerobic Respiration Krebs Cycle Electron Transport Chain Alcoholic Fermentation Lactic Acid Fermentation

Cellular respiration Chemical equation C6H12O6 + 6O2 --------> 6CO2 + 6H2O + 36 ATP Word equation Glucose + oxygen --carbon dioxide +water+ATP

Glycolysis Begins with one 6 carbon glucose molecule which will split into two 3 carbon pyruvic acids Happens in the cytoplasm 2 ATP’s will be produced Glucose + 2 ATP 2 Pyruvic Acids

Aerobic Respiration Must have oxygen present Happens in the mitochondria Produces 36 ATP’s from one glucose molecule Has 3 steps 1Glycolysis 2Krebs Cycle 3Electron Transport Chain

Aerobic respiration Step 1: Glycolysis Happens in the cytoplasm 2 ATP’s & 2 pyruvic acids made Step 2: Krebs Cycle Happens in the mitochondria 2 more ATP’s made Step 3: Electron Transport Chain Happens in the mitochondria 34 more ATP’s are made Total ATP’s for AR= 36 (two are used up in the process)

Picture of a mitochondrion

Anaerobic respiration Oxygen is not present Only 2 ATP’s made (from Glycolysis) 2 types Alcoholic Fermentation- done by yeast and other microorganisms Lactic Acid Fermentation- occurs in muscle cells

Alcoholic Fermentation (anaerobic respiration) Glycolysis (No oxygen) Alcoholic Fermentation Ethyl Alcohol + CO2

Lactic Acid Fermentation (anaerobic respiration) Glycolysis (No oxygen) Lactic Acid Fermentation Lactic Acid
