Question | Answer |
---|---|
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 |
