Question

reaction. Which letters indicate the activation and free energy of the reaction, respectively? A Aand B B AandC C Band D D. Dand B 55 Rfering to the previous question, enzymesaccelerate biochemical reactions by A Increasing the energy change associated with B B Increasing the energy change associat ed with D C Decreasing the energy change assocated with B D Decreasing the energy change associated with D 56. The reaction represented by the figureatoe- A isendergonic B isendothermic C is a reaction in which the products have more potential energy than the reatants D is exergonic and most of it is ganer ated in the 57. The immediate source of energy in animal cells is A ADP/glycolysis C ATR Gycolysis D ATPITCA cyde E ATP oxddative phosphorylation 58 Gyoolysis is said to have an investment phase and a pay-off phase In the investment phase, molecules of are utilized while in the pay-off phasemolecuies of ae produced A 2/AT4/ATP E 2ADPWATP 59. Much of the suitability of ATP as an energy intermediary is related to the instability of the bonds

Answer 1

56) answer D Exergonic reaction : In exergonic reaction energy relesed and gibs free energy is Negative. Exergonic reaction substrates always have more energy than the products so reaction occurs spontaneously.

57) Answer E ATP / Oxidative phosphorylation : Because ATP is energy currency of cell. Glycolysis only produces 2 ATP but other 36 ATP are produced in Oxidative phosphorylation also known as Electron transport chain. ATP are produced by ATP synthase by using proton motive force

58)Answer A 2 ATP and 4 ATP : ATP are used for phosphorylation of glucose at1 and 6 th position
