Homework Answers
High energy bonds;
ATP ( Adenosine triphosphate)
Adenosine- P- P- P, The terminal phospho anhydrous bond is the high energy bond in ATP which gives energy when it is hydrolysed. It is an exergonic reaction with -7.3 Kcal/mol. But both last two bonds of ATP are high energy bonds. Even ADP hydrolysis gives energy but is is lesser than the terminal one (ATP).
Acetyl CoA-SH (Acetyl Coenzyme A)
Thio ester linkage of acetyl CoA is the high energy bond. Hydrolysis of this thioester bond is an exergonic process with (-31.5kj/mol).
Carboxylated biotin
The bond between biotin and CO2 is the high energy bond in it. Caboxylation of biotin accompanied with the hydrolysis of ATP molecule.
