Module 10 Set 3

Cell energy cycle 1st Aerobic respiration/ Anaerobic respiration/ Fermentation/ Photosynthesis
Cell energy cycle 2nd ADP+Pi↭ATP
Cell energy cycle 3rd Chemical work/ Transport work/ Mechanical work
Other energy suppliers GTP, CTP, UTP
Thermodynamics 1st law Energy cannot be created or destroyed, only converted
Thermo 1st law ex chemical energy in food ▶ chemical energy in ATP ▶ mechanical energy in muscle contraction
Thermodynamic 2nd law ex 25% chemical energy of gasoline converted to move car, rest is loss as heat
Thermodynamic 2nd law ex Muscle convert chemical energy in ATP to mechanical energy, some lost as heat
Entropy Measure of randomness or disorder
Thermodynamics 2nd law Energy cannot be changed from one form to another without the loss of usable energy
Organized/usable forms of energy have: low entropy
Unorganized/less stable forms of energy have: high entropy
Energy conversions result in heat and therefore entropy is: always increasing
If A+B ▷C+D, A and B are ___ and C and D are ___ Reactants; Products
Free energy (G) Amount of energy that's free to do work AFTER chemical reaction
Change in free energy noted as: △G
-△G means Products have Less free energy than reactants; The reaction occurs spontaneously
