Answer:
Two ATP molecules are needed to give the required energy for this reaction.
Explanation:
In any chemical reaction in our body, ATP is the major energy source that is produced or synthesized by the powerhouse of the cell, mitochondria. ATP stands for Adenosine Triphosphate and is known as the energy currency of our cells. The energy for any chemical reaction is taken by the ATP after its hydrolysis. The hydrolysis of one or single molecule of ATP provides or liberates energy equal to 7.3-7.5 kcal/mol of energy or in other words, ΔG = - 7.3 kcal/ mol.
Hence for this reaction, the number of ATP required is:
Number of ATP =
∴Number of ATP = 2 approx.
Hence two ATP molecules are needed.
