Question

"Which statement is true about the removal of a terminal phosphate" from ATP? Choose one: A. The reaction is associated with a positive change in ΔG°. B. The reaction is a condensation reaction. C. The reaction is energetically favorable.

Answer 1

C. The reaction is energetically favorable.

Step-by-step explanation:

The reaction which shows the removal of the terminal phosphate from the ATP is shown below:

`ATP+H_2O\rightarrow ADP+P_i+\ energy`

The Gibbs' free energy change of this reaction,
`\Delta G^0=-7.3\ kcal/mol`

Hence, Option A is not correct.

It is a type of hydrolysis reaction in which water is being added to the molecule.

Hence, Option B is not correct.

The Gibbs' free energy change is negative which means that the reaction is energetically favorable.

Option C is correct.
