Question

44 UNIT 3 | Chemistry 5. An increase in blood carbon dioxide levels causes an increase in blood hydrogen ion levels. Explain What effect does an increase in blood hydrogen ion levels have on the pH of the blood? 6. Activity 3: Observing the Role of Buffers L. Define buffer.a batse Sabien resist is a Goluhrn that 2. What was the role of each of the following substances in the demonstration of the role of buffers? a. Sodium bicarbonate b HCI c. Bromocresol purple 3. How did the effectiveness of sodium bicarbonate compare to the effectiveness of the three antacids tested in Part B of Activity 3 Activity 4: Analyzing Enzymatic Activity l. Identify each of the molecules as a monosaccharide (M), disaccharide (D), or polysaccharide (P) e. Lactose _ f. Glycogen & Galactose a. Sucrose- Glucose c. Starch d.Fructose 2. Explain the difference between a dehydration synthesis reaction and a hydrolysis reaction. 3. Match each of the following levels of structural organization of proteins with its description primary secondary 1. compact, globular structure 2. sequence of amino acids 3. alpha helix or beta-pleated 4. interaction of two or more polypeptide chains c. tertiary d.quaternary Each enzyme has a pocket on its surface called a(an) 4. a substrate binds. to which

Explanation / Answer

5.) This is because an enzyme called carbonic anhydrase rapidly converts CO2 and water into a substance called carbonic acid (H2Co3), which in turn can rapidly turn into HCO3- and free hydrogen ions (H+) hence, incresed hydrogen ion increase .

6.) blood hydrogen level determine the ph of blood as

pH=-log[H+] , A solution with a concentration of hydrogen ions higher than 10-7mol/L is acidic.

Activity 4.

1. sucrose = disaccharide

galactose=monosaccharide

starch= polysaccharide

Fructose =monosaccharide

lactose= disaccharide

glycogen= polysaccharide

galactose= monosaccharide
