Breaking of terminal phosphate of ATP releases about ___________ Kcal of energy?

Correct answer: D. 7.3

  • A. 6.1
  • B. 6.3
  • C. 7.1
  • D. 7.3

Explanation

Hydrolysis of ATP's terminal phosphate releases about 7.3 kcal per mole of ATP under standard biochemical conditions. Students may choose 6.1 kcal per mole because energy values vary with conditions, but 7.3 kcal per mole is the standard textbook value used for ATP hydrolysis.
