Study Notes
ATP and ADP Structure
- ATP (adenosine triphosphate) has three phosphate groups, while ADP (adenosine diphosphate) contains two.
- Both ATP and ADP consist of adenosine, phosphate groups, and ribose sugar.
Energy Storage
- ATP stores more energy than ADP, specifically in the bonds connecting the second and third phosphate groups.
Conversion Processes
- ADP converts to ATP by adding a phosphate group, producing ATP and water in the process.
- ATP is converted to ADP through hydrolysis, which breaks the bond of the third phosphate, releasing energy.
ATP-ADP Cycle
- The ATP-ADP cycle describes the continuous regeneration of ATP in cells: ADP forms when ATP loses a phosphate, and ATP is restored as ADP gains a phosphate.
Cellular Energy Needs
- Cells require energy from ATP breakdown for various processes, including movement, maintenance of body temperature, active transport, biochemical reactions, protein synthesis, and DNA replication.
ATP Components
- ATP is composed of adenine, ribose, and three phosphate groups.
Acronyms
- ATP stands for adenosine triphosphate.
- AMP (adenosine monophosphate) is derived from ATP when two phosphate groups are removed.
Reaction Types
- Endergonic reactions require energy input to proceed, such as ADP + P + energy forming ATP.
- Exergonic reactions release energy, exemplified by ATP converting to ADP + P + energy.
