Make a list of the anions of the six strong monoprotic acids discussed in lecture. These anions are said to have no effect on the pH of an aqueous solution. The same is true for solutions of strong bases - their conjugate acids (which are Group 1 or Group 2 cations) are very weak acids, and therefore, have virtually no effect on the pH of the solution.

4. Make a list Group 1 and Group 2 cations, and note that these ions are said to have no effect on the pH of an aqueous solution with the exception of Be2+. The situation is different, however, for the conjugate acid of a weak base, or the conjugate base of a weak acid.

5. A weak base: Write a balanced equation for the protonation of ammonia, using water as a reactant.______________________________________________ a. What species is the conjugate acid of ammonia? ________________ b. The Kb of ammonia is 1.8 x 10-5 . What is the Ka of its conjugate acid? Show work.

6. Hypoiodous acid (HIO) has Ka = 2.3 x 10-11. Which is a stronger acid, HIO or NH4 +? Explain your reasoning. Acids, Bases, Salts and Buffers Prelab Assignment revised by Bruce E. Wilcox, Fall 2017 Name _____________________________ Assignment: Complete this assignment (and the reproduction in your manual) and hand this form in at the beginning of lab. Also copy the work from pages 3 – 4 into your notebook. 2 Now you have seen that the conjugate acid of a weak base can exhibit significant acid behavior. What about the conjugate base of a weak acid?

7. Write the balanced equation for the ionization of nitrous acid in water. _____________________________________________________ a. The Ka of HNO2 is 4.3 x 10-4 . What is the Kb of its conjugate base? Show work.

1. What is the effect that glyceraldehyde 3 phosphate dehydrogenase has on cells?

2. What would happen in the absence of Pol1, if the the primers are not replaced by DNA and if Pol 3 was absent and no DNA synthesis occured?

3. How does the phase where Glucose forms glucose 6 phosphate differ from the phase where PGA forms pyruvate in terms of reaction coupling to overcome thermodynamic hurdles for glycolysis to occur ***

Aerobic Cellular Respiration (getting energy from food) involves four steps: Glycolysis, the Intermediate Acetyl CoA Reaction (Prep Reaction), the Citric Acid (Krebs) Cycle, and the Electron Transport Chain. State:

where each of the four steps takes place in a cell

how many ATP are generated at each step, if at all

what is the starting (ie. glucose or pyruvate) and ending substance for each step

The preparatory phase of glycolysis converts one 6-carbon sugar into two 3-carbon sugars and uses two molecules of ATP while the payoff phase of glycolysis converts those two 3-carbon sugars into 2 molecules of pyruvate and generates two molecules of NADH and four molcules of ATP.

True

False

True

False

Case 1: Pyruvate Kinase (PK) catalyzes the rate-limiting, ATP-generating step of glycolysis in which phosphoenolpyruvate (PEP) is converted to pyruvate. Multiple isoenzymes of pyruvate kinase exist in mammals: type L, which is found in the liver and kidneys; type R, which is expressed in erythrocytes; type M1, which is found in tissues such as muscle and brain; and type M2, which is present in self-renewing cells such as embryonic and adult stem cells. 1) Under normal conditions, describe all the ways in which pyruvate kinase is regulated in the cell? Many types of cancer cells are predominantly glycolytic and over express the oncoprotein MYC. Interestingly, the classical oncoprotein MYC has been found to promote preferential expression of pyruvate kinase type M2 over pyruvate kinase type M1. The isoform M2 is characteristically found in a low activity state and is ineffective at promoting glycolysis (When compared to pyruvate kinase type L or type M1). 2) This logic seems counter-intuitive for a glycolytic tissue. What is the rationale for this mechanism and what other pathways may cancer cells be diverting substrate to?

the peotide bond between two amino acid is a covalent bond. true or false?
