Adenosine Triphosphate Atp Is A Mononucleotide Biology Essay Introduction. Adenosine triphosphate (ATP) is a mononucleotide with an adenine base and a ribose sugar to which three phosphate groups are linked. The covalent bond between the second and the third phosphate group is unstable and easily broken by hydrolysis (Kent, 2000). ATP can.
The correct answer is (A). The Calvin Cycle can be broken down into 3 steps: (1) Carbon fixation, which incorporates each CO 2 molecule by attaching it to a 5-carbon sugar (ribulose-1,5-bisphosphate), (2) Reduction, where each molecule of 3-phosphoglycerate receives an additional phosphate group from ATP and hydrogen from NADPH forming glyceraldehyde-3-phosphate, and (3) Regeneration of the CO.
