NEET Biology Respiration In Plants Question Bank Assertion and Reason

  • question_answer
    Assertion : During the hydrolysis of typical chemical bonds, about 3000 calories per mole are liberated. Reason : ATP also yields about 3000 calories per mole after the release of any one of the two terminal phosphates.

    A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion

    B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion 

    C) If the assertion is true but the reason is false

    D) If both the assertion and reason are false

    E) If the assertion is false but reason is true

    Correct Answer: C

    Solution :

    During the hydrolysis of typical chemical bonds, about 3000 calories per mole are liberated. The release of any one of the two terminal phosphates of ATP yields about 7300 calories per mole, instead of the 3000 calories from common chemical bonds. The standard free energy of hydrolysis of ATP to ADP and phosphate is -7.30 K cal at pH 7.0 and temperature \[{{37}^{o}}C\]in the presence of excess\[M{{g}^{2+}}.\]
