Overall Reaction:Reactants, products, when in the process, where in the cell C6H12O6 + 6 O2  6 H2O + 6 CO2 Glycolysis ETC ETC Krebs Cytoplasm INNER MEMBRANE Matrix

Label and Identify where the reactions occur

Label and Identify where the reactions occur Outer membrane Inner membrane (ETC) Intermembranous space Matrix (Krebs Cycle) Cristae Cytoplasm (Glycolysis)

Energy Yields Glycolysis Krebs ETC Total

Energy Yields Glycolysis = 2 ATP – It requires 2 ATP to split the glucose and generates 4 ATP as a result, so we only count a total of 2 Krebs = 2 ATP ETC = 34 ATP Each NADH provides enough energy to generate 3 ATP and Each FADH2 provides enough energy to generate 2 ATP 10 NADH = 30 and 2 FADH2 = 4 Total = 38 ATP

Path of a Red Blood Cell Through The Body

Vena Cava  Right Atrium  Atrioventricular Valve  Right Ventrical  Semilunar Valve  Pulmonary artery  lungs  pulmonary vein  Left Atrium  Atrioventricular valve  Left Ventrical  Semilunar Valve  Aorta  Arteries  Atertioles  Capillaries  Venules  Veins  Vena Cava

Control of Respiration Contraction of Diaphragm and Intercostal muscles CO2 concentrations increase forming carbonic acid pH of blood decreases Higher external pressure forces air into lungs Enlargement of Rib Cage Diaphragm and intercostal muscles relax expelling air Lower pressure inside lungs Chemosensors in medulla oblongata and carotid artery signal diaphragm to contract harder and more often to increase the flow of air into and out of lungs
