BSCI170 Lecture Notes - Atp Hydrolysis, Bioluminescence, Endergonic Reaction
Document Summary
Life is about work :: acquiring and using energy is a fundamental property of life, remember: energy is the capacity to make a change against a resisting force. In a biological context, energy is the ability to do work. Biological work refresher: biosynthesis, mechanical activity, transport (active, bioluminescence. Hydrolysis of adenosine triphosphate: atp: this reaction spontaneously moves left, making this reaction move forward (to the right) requires an input of energy, monomer + monomer + energy dimer + h2o, g = , g = . Atp structure and function: atp has multiple roles in the cell, subunit for synthesis of rna (and dna, starting product for synthesis of cyclic amp (camp) Intracellular signaling molecule: energy coupler for endergonic reactions. Atp: humans don"t get our energy directly in the form of atp, some organisms absorb energy from the sun and convert it into atp or into other organic molecules that other organisms can consume and convert into atp.
