(a)
To calculate: The concentration of PEP at 25°C, assuming that the pyruvate kinase reaction is at equilibrium in the cell.
Introduction:
Glycolysis is the first stage of
(b)
To compare: The values of concentration of PEP at 25 °C with the physiological concentration of PEP in human erythrocyte (0.23mM).
Introduction:
Glycolysis is the first stage of cellular respiration in which glucose is broken down into two pyruvic acid molecules by the action of enzymes which results in formation of net two ATP molecules. Phosphoenolpyruvate is a phosphoryl group donor in the synthesis of molecules of ATP during glycolysis.

Only ONE of the five compounds below can be prepared by an aldol condensation in which a single carbonyl compound is treated with base. Which one is it? To solve this problem, reverse the aldol condensation that formed each of these molecules to find out what two molecules came together to make the products. The one in which the two molecules are identical is the answer. Ph Ph ཚིག གནས ག ནཱ ཀ ན ཀནཱ A Ph H B Ph Ph H D Ph. Ph Ph E Harrow_forward
