BIOL10002: Lecture 6 - Energy Harvesting Pathways
Topics
-ATP
-Glycolysis
-Fermentation
-TCA cycle
-NAD & NADH
-Aerobic Respiration
-ATP synthase
Coupling of Reactions
-Couple reaction which releases energy with reaction which uses energy (exothermic & endothermic)
•usually achieved why using cofactors (enzyme partners)
-ATP & coenzyme
•ATP: high energy, charged molecule
•Structure: base, sugar, 3 phosphate groups (final phosphate goes On & Off)
•Discharge & recharge of ATP (adenosine triphosphate) : removal of terminal phosphate group
creates ADP (adenosine diphosphate)
-Done by coupling reactions: during exogonic reactions (catabolism / respiration), energy is
related from oxidation reaction. Energy is used to convert ADP to ATP(charged form)
-When energy is needed (cell movement, active transport), ATP —> ADP + Pi
**ALL LIVING THINGS USE ATP FOR ENERGY — UNITY OF BIOCHEMICAL PROCESS (PROOF OF EVOLUTION**
-D
-All energy comes from the sun —> photosynthesis —> produce complex carbohydrates (glucose) —>
carbohydrate is oxidized again (process of GLYCOLYSIS) to produce pyruvate
•Aerobic respiration - Complete oxidation of glucose ; Waste products are H2O & CO2 — can
recharge 32 ATP
•Anaerobic respiration (fermentation) - incomplete fermentation ; waste products are CO2 &
Organic compounds — can recharge 2 ATP

Document Summary
Couple reaction which releases energy with reaction which uses energy (exothermic & endothermic: usually achieved why using cofactors (enzyme partners) Atp & coenzyme: atp: high energy, charged molecule, structure: base, sugar, 3 phosphate groups ( nal phosphate goes on & off, discharge & recharge of atp (adenosine triphosphate) : removal of terminal phosphate group creates adp (adenosine diphosphate) Done by coupling reactions: during exogonic reactions (catabolism / respiration), energy is related from oxidation reaction. Energy is used to convert adp to atp(charged form) When energy is needed (cell movement, active transport), atp > adp + pi. **all living things use atp for energy unity of biochemical process (proof of evolution** !1: cells use compartments; they set up a difference in potential (from protons) then to control the difference in potential, protons pass through a gateway back into the compartment they were originally from. Gateway uses this method to harvest energy to produce atp.
