HMB472H1 Chapter Notes - Chapter 2: Polysaccharide, Chitin, Membrane Transport Protein
Document Summary
1st law of thermodynamics: energy can be converted from one form to another but the total amount of energy remains constant. 2nd law of thermodynamics: [law of entropy] universe is becoming more chaotic. When energy is transferred, some energy is blocked in a way that increases the entropy [randomness] of the system. Joules is the si unit of energy but calorie is the scientific unit. Radiant energy: energy that can be produced by an object and then transmitted to something else like heat. Mechanical energy: combination of both potential + kinetic energy. Electrical energy: combination of both potential + kinetic energy. Used for the downward movement of particles down a gradient. Chemical energy: type of potential energy that is held b. w chemical bonds. Thermal energy: type of kinetic energy/movement of particles/increase temperature. Plants capture light [photon] and pass it on to plants. Herbivores than eat plants + carnivores eat the herbivores.
