Stored energy because of structure or location, +ΔG, anabolic, endergonic.
Gibbs free energy, can do work. -ΔG means a rxn gives off energy, it provides power. +ΔG means rxn needs energy, it will not run unless energy is added, every rxn has a specific ΔG, ΔG is never changed in a reaction.
breaking down, releasing energy, -ΔG, exergonic.
building up, needs energy, +ΔG, endergonic
energy of a molecule due to its shape, potential.
heat associated with random motion of molecules.
Laws of thermodynamics
1. conservation of energy, can't be created or destroyed.
2. Everything is moving towards chaos, every energy transformation increases entropy. spontaneous processes requiring no outside energy increase entropy.
these laws govern all energy transformations.
release energy, amount released equals the difference in potential energy between reactants and products.
Requires input of energy. Input equals difference in potential energy of reactants and products.
Sum total of all endergonic and exergoninc reactions in the cell.
Adenine+Ribose+P~P~P. 1x glucose =36 ATP. Captures and transferes free energy. Link of P's like a compressed spring, release = energy released. Hydrolysis releases energy. ATP⇒ADP+Pi (means PO4) Phosphate groups used to phosphorylate, releases 7.3 kcal.
Adding phosphate group to another molecule, endergonic reactions.
endergonic reactions of cellular respiration phosphorylate ADP reforms ATP
