Question

Mark the incorrect statement about ATP :

• A. It is a nucleotide
• B. It contains the purine adenine
• C. The enzyme-catalysed hydrolysis of $ATP$ to $ADP$ and $AMP$ is accomplished by absorption of energy
• D. Energy is stored in the cell in the form $ATP$

Answer 1

The correct option is C The enzyme-catalysed hydrolysis of $ATP$ to $ADP$ and $AMP$ is accomplished by absorption of energy

Adenosine triphosphate (ATP) is a nucleoside triphosphate used in cells as a coenzyme, often called the "molecular unit of currency" of intracellular energy transfer.

The enzyme-catalysed hydrolysis of $ATP$ to $ADP$ and $AMP$ is exothermic reaction.

$ATP+H_{2}OADP+P_i$ $G$ = $30.5$ $kJ/mol$ ($7.3kcal/mol$)

$ATP+H_{2}OAMP+P{P}_i$ $G$ = $45.6$ $kJ/mol$ ($10.9kcal/mol$)
