ATP

ATP

ATP is needed to provide energy for:

• Movement
• Maintaining Body Temperature
• Anabolic Process
• Active Transport
• Secretion

Strutural Features:

• Small, water soluble - easily transported around the cell
• contains 3 phosphate groups
• ATP is hydrolysed (water is added) to produce ADP and Pi (phosphate)
• ADP can be converted back to ATP by the addition of Pi molecule

Production of ATP happens in 3 ways:

• Photophosphorylation - occurs on the membrane of the chloroplast during photosynthesis
• Oxidative Phosphorylation - occurs on the membrance of the mitochondria during aerobic respiration
• Substrate-level Phosphorylation - occurs in both plant and animal cells when a phosphate group is dontated to ADP
