1.1.5 Production of Substances Enzymes Hormones
1.1.6 Maintenance of Body Temperature (Birds & Mammals)
1.2 How ATP Stores Energy
1.2.1 Phosphate Bonds Low Activation Energy Large Energy Release
1.2.2 ATP + H2O > ADP + Pi + Energy
1.3 Synthesis of ATP
1.3.1 Addition of Phosphate Molecules Photophosphorylation Thylakoid Electron Carrier Chain Oxidative Phosphorylation Mitochondrial Electron Carrier Chains Substrate-Level Phosphorylation Phosphate From Donor Molecules Eg: Triose Phosphate in Glycolysis
1.4 Roles of ATP
1.4.1 Immediate Energy Source Single Reaction, Very Rapid Small, Manageable Quantities Released Directly to Reaction Requiring It
2 Respiration
3 Photosynthesis
