seconds‚ pH = 7.4 4. Did the pH level of the blood change at all during normal breathing? If so‚ how? The pH did not change during the normal breathing. 5. Was the pH level always within the “normal” range for the human body? Yes it was. 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No it did not change either. Activity 2a: Hyperventilation – Run 1 1. At 20 seconds‚ pH = 7.48 2. At 40 seconds‚ pH = 7.52 3. At 60 seconds‚ pH = 7.65 4. Maximum pH = 7.65

Lab 8: Isopentyl Acetate CHM 2211L October 22‚ 2014 Abstract Many esters are naturally occurring compounds that are responsible for the fragrance of fruits and flowers. Isopentyl Acetate is the compound responsible for the smell of bananas. However‚ when Isopentyl acetate is treated with H3O+ it will hydrolyze back into the carboxylic acid‚ which will change the fragrance. In this experiment 3.11g of Isopentyl Acetate were produced with a 51.92 percent yield. Introduction Esters are carboxylic

Erythrocytes Survive 120 Days Hemoglobin * Globin: 4 folded polypeptide chains * Heme: Iron group in each polypeptide that binds 02 Enzymes: * Glycolytic: generate energy through glycolysis due to lack of mitochondria * Carbonic anhydrase: for transport of CO2 into HCO3 Erythropoiesis: * regeneration of new cells in the bone marrow Erythropoietin (hormone): * when kidneys detect not enough 02 they secrete this hormone which stimulates erythropoiesis‚ increasing 02 capacity
