Question

Glutamic Ammonia Glutamine acid 1. The endergonic reaction is 2. The exergonic reaction is 3. How much energy is released by the exergonic reaction? 4. How much energy is required by the endergonic reaction? 5. The amount of energy lost as entropy is. a. +3.4 kcal/mol b. -7.3 kcal/mol c. -3.9 kcal/mol d. -11.2 kcal/mol e. -0.5 kcal/mol 6. The amount of energy lost as heat is.. a. +3.4 kcal/mol b. -7.3 kcal/mol c. -3.9 kcal/mol d. -11.2 kcal/mol e. -0.5 kcal/mol 7. True (A) or False (B): An endergonic reaction fuel by the breakdown of ATP to ADP can consume as much as 7.3 kcal/mol of energy. Explain your answer

Explanation / Answer

1.Endergonic reaction is a reaction in which energy is absorbed. Endergonic reactions absorb free energy; the G for that reaction will be a negative value.

Glutamic acid+NH3-----------------> glutamine

2.Exergonic reaction is a reaction in which energy is released.Exergonic reactions release free energy; the G for that reaction will be a negative value.

ATP + H20 -------------> ADP + Pi

3.Energy released by exergonic reaction - 7.3kcal/mol

4.Energy required by endergonic reaction- +3.4kcal/mol

7.true

In a coupled reaction energy required by 1 process is supplied by another process. Here also this is happening as the above reaction is an endergonic reaction with positive G and when it is coupled with ATP hydrolysis reaction with negative G then the reaction proceeds as the overall G becomes negative.
