Question

chapter 8: an introduction to metabolism

1. here is a molecule of atp. label it. use an arrow to show which bond is likely to break.

triphosphate group (3 phosphate groups)
adenine
ribose
a. by what process will that bond break?

Explanation:

Step1: Identify components

ATP consists of adenine, ribose and tri - phosphate group. Adenine is a nitrogen - containing base, ribose is a 5 - carbon sugar, and there are three phosphate groups.

Step2: Determine bond to break

The outermost phospho - anhydride bond in the tri - phosphate group is the one likely to break. It is a high - energy bond.

Step3: Identify the process

The process by which this bond breaks is hydrolysis. Water is used to cleave the bond.

Answer:

Label the parts as adenine (nitrogen - containing base), ribose (5 - carbon sugar), and tri - phosphate group (three phosphate groups). Draw an arrow pointing to the outermost phospho - anhydride bond in the tri - phosphate group. The process by which the bond breaks is hydrolysis.
