Question

Choose the correct answers from the alternatives given.
The phosphate bonds of ATP are referred to as high-energy bonds because their

• A. Hydrolysis has a relatively high free energy of activation
• B. Formation releases a relatively large amount of energy
• C. Hydrolysis is exergonic
• D. Bond energy is relatively high

Answer 1

The correct option is C Hydrolysis is exergonic

ATP is the primary molecule associated with storage and transfer of energy in cells. It is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate group. The phosphate groups in ATP are connected to each other by two high-energy bonds called phosphoanhydride bonds. Energy is released when these bonds are broken down by a process called hydrolysis, which is an exergonic reaction. The energy thus released is used for cellular reactions.

So the correct option is "Hydrolysis is exergonic"
