Question

this new compound with one fewer phosphate groups than before is called adenosine diphosphate (adp)
what does the prefix di - mean?
list the four \building blocks\ that are needed to form one adp molecule:
1)__________________ 3)__________________
2)__________________ 4)__________________
explain how an atp molecule is changed to an adp molecule.
what is released when atp is changed to adp?____________________

Explanation:

• Prefix "di -": In the context of ADP (adenosine diphosphate), the prefix "di -" means two. This is because ADP has two phosphate groups.
• Building blocks of ADP:
• Adenine: It is a nitrogen - containing base.
• Ribose: A five - carbon sugar.
• Two phosphate groups: These are the "phosphate" parts of adenosine diphosphate.
• ADP is formed from ATP (adenosine triphosphate).
• ATP to ADP conversion: An ATP molecule has three phosphate groups. When one of the phosphate groups is removed (through a hydrolysis reaction), ATP is changed to ADP. The reaction can be represented as \(ATP + H_2O

ightarrow ADP+P_i\) (where \(P_i\) is an inorganic phosphate).

• Release during ATP to ADP: Energy is released when ATP is changed to ADP. This energy is used for various cellular processes such as muscle contraction, active transport, and biosynthesis.

Answer:

• The prefix "di -" means two.
• The four building blocks of ADP are: 1) Adenine; 2) Ribose; 3) Two phosphate groups; 4) ADP is formed from ATP.
• An ATP molecule is changed to an ADP molecule by the removal of one phosphate group (through hydrolysis).
• Energy is released when ATP is changed to ADP.
