- ATP
- Structure
- Adenine
- Ribose
- Phosphates
- how ATP stores energy:
- Synthesis of ATP
- Conversion of ATP to ADP is a reversible reaction.
- The reaction is catalyzed by the enzyme ATP synthase
- Condensation reaction
- ADP TO ATP
- Photophosphorylation
- Oxidative phosphorylation
- Substrate- level phosphorylation
- Roles of ATP
- Metabolic process
- Energy needed to build up macromolecules from their basci units
- Movement
- Provides energy for muscle contraction
- Muscle filaments to slide past one another
- Active transport
- Change the shape of carrier proteins
- Secretion
- Needed to form Lysosomes necessary for the secretion of cell products
- Activation of molecules
- Phosphorylate other molecules and make them reactive
- Lowers activation energy in enzyme-catalyzed reactions
- Metabolic process
- Structure
- The bonds between phosphates are unstable
- Therefore have a low activation energy
- When the bonds break they release a considerable amount of energy.
- ATP + (H20) ---> ADP + Pi + E
