ATP, Photosynthesis & Respiration
- ATP & Energy
- Why Do Organisms Need Energy?
- Metabolism
- Movement
- Locomotion
- Blood Circulation
- Active Transport
- Maintenance, Repair &
Division of Cells
- Production of Substances
- Enzymes
- Hormones
- Maintenance of Body Temperature
(Birds & Mammals)
- How ATP Stores Energy
- Phosphate Bonds
- Low Activation Energy
- Large Energy Release
- ATP + H2O > ADP + Pi + Energy
- Synthesis of ATP
- 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
- Roles of ATP
- Immediate Energy Source
- Single Reaction, Very Rapid
- Small, Manageable Quantities
- Released Directly to Reaction Requiring It
- Respiration
- Photosynthesis
- Leaf Adaptations
- Large Surface Area
- Numerous Stomata for Gas Exchange
- Air Spaces for Diffusion
- Transparent Cuticle
- Thin for Short Diffusion Distance
- Light Dependent Reaction
- Chloroplast Adaptations
- Large Thylakoid Surface Area
- Enzymes on Granal Membrane
- DNA & Ribosomes for Protein Manufacture
- Photolysis of Water
- Water Split by Light Energy to
Replace Chlorophyll's Lost
Electrons When Light Hits It
- 2H20 > 4H+ (Protons) + 4e- (Electrons) + O2
