Anabolic
Reactions in which large molecules are broken down to smaller ones
Catabolism
Reactions which release energy
Catabolism
A common high-energy compound composed of a purine (adenine), a sugar (ribose), and 3 phosphate groups
ATP - Adenosine triphosphate
Capacity to do work
Energy
Pairs of chem rxns in which some of the energy released from the breakdown of one compound is used to create a bond in the formation of another compound. Example:
Coupled reactions; reactions that occur simultaneously with the hydrolysis of ATP to use the energy released.
The bonds connecting the 3 phosphate groups of ATP are often described as _____, referring to their _____
High-energy bonds; readiness to release their energy
How do its negative charges on the phosphate groups affect ATP
Vulnerable to hydrolysis
Cells require energy, so ____ rxns break down high energy bonds of ATP, splitting off one or two _____ and _____ energy
Hydrolysis reactions readily break the high energy bonds of ATP, splitting off one or two phosphate groups and releasing energy
ADP + P => ATP is an example of _____ reaction because it ____ energy
Anabolic; uses (requires)
