Question
In glycolysis, fructose L6-bisphosphate is converted to two products with a standard free-energy change (Delta G' degree) of 23.8 kJ/mol. Under what conditions encountered in a normal cell will the free-energy change (Delta G) be negative, enabling the reaction to proceed spontaneously to the right? a) Under standard conditions, enough energy is released to drive the reaction to the right. b) The reaction will not go to the right spontaneously under any conditions because the Delta G' degree is positive. c) The reaction wall proceed spontaneously to the right if there is a high concentration of products relative to the concentration of fructose 1, 6-bisphosphate. d) The reaction wall proceed spontaneously to the right if there is a high concentration of fructose 1, 6-bisphosphate relative to the concentration of products. e) None of the above conditions is sufficient. Match the cofactors below with their roles in the pyruvate dehydrogenase complex reaction. Cofactors: Roles: A. Coenzyme A (CoA-SH) ___ Initial electron acceptor in oxidation of pyruvate. B. NAD^+ ___ Accepts the acetyl group from reduced lipoic acid. C. Thiamine pyrophosphate (TPP) ___ Oxidizes FADH_2. D. FAD ___ Attacks and attaches to the central carbon in pyruvate. E. Lipoic acid in oxidized form ___ Oxidizes the reduced form of lipoic acid. What is the purpose of phosphorylation in glycolysis? How is it accomplished? What does this mean for glycolytic intermediates inside the cell?Explanation / Answer
ANSWER 12..OPTION [ D ] CORRECT ...BECAUSE IF G0 POSITIVE THAN G NEGATIVE IS ONLY CONDITION WHEN ACCORDING TO NERNST EQUATION
LOG[ P/R] = -VE ..ITS HAPPEN WHEN REACTANT MORE THANPRODUCT.
NERNST EQUATION [ G = G0 + nRTlog[ product]/[reactant] ]
13..(E) LIPOIC ACID IN OXIDIZED FROM = INITIAL ELECTRON ACCEPTOR IN OXIDATION OF PYRUVATE
( A) COASH ACCEPTS THE ACETYL GROUP FROM REDUCED LIPOIC ACID
( D) FAD OXIDIZES THE REDUCED FROM OF LIPOIC ACID
(C) THIAMINE PYROPHOSPHATE [TPP] = ATTACKS AND ATTACHES TO THE CENTRAL CARBON IN PYRUVATE.
(B) NAD OXIDIZES FADH2
14..provide path way of glycolysis with catalyst reaction ,phosporylation also a process of energy production in ATP from ,step by step reaction takes place for final process also call as intermediate because its stable and provide a sutable place for catalyst..
