Homework Answers
Ans:
a. ATP is an energy currency of a cell. Hydrolysis of ATP is an energetically favourable reaction.
ATP+H2O⇋ADP+Pi+energy.
This hydrolysis reaction is an exergonic reaction.
(Importance of this reaction: This exergonic reaction is used by the cell to fuel the other reactions like;
Glucose + ATP <--> Glu-6P + ADP
Glucose to Glu-6P is endergonic reaction and the energy require for this reaction is provided by hydrolysis of ATP.)
b. As the reaction
ATP+H2O⇋ADP+Pi+energy
is spontaneous or energy favorable reaction the delta G of this reaction is negative.

4. Draw a free energy reaction coordinate diagram for both a generic endergonic and a generic exergonic reaction (label each). Make sure to label the x- and y-axes. Now label where reactants and products should go on the figure. Draw something that illustrates the free energy change for each reaction. Now write something like the following next to your figures: “reactants <—> products”. a. What do the reaction coordinate diagrams have to do with the text you just wrote? b. What...
