BI110 Lecture Notes - Lecture 16: Adenosine, Potential Energy, Ribose
Document Summary
Metabolism: a way to encode/transmit information, a membrane separating inside from out, energy. Adenosine triphosphate (atp: the bonds linking these phosphate groups have high potential energy, 3 phosphate groups, ribose sugar and adenine, by breaking phosphate bonds, energy is released and used by body. Metabolic classification: energy source, phototrophs = energy from sunlight, chemotrophs = energy from chemical compounds, carbon source, autotrophs = carbon from inorganic sources (such as co2, heterotrophs = carbon from organic compounds. Metabolism: the chemical reactions that convert molecules into other molecules and transfer energy in organisms. Catabolism: breakdown of molecules into smaller units, producing atp, breaking macromolecules, carbs, proteins, fats, nucleic acids. Anabolism: building of molecules from smaller units, requiring an input of energy, atp, building from subunits, sugars, amino acids, fatty acids, nucleotides. Energy: energy = the capacity to do work, kinetic energy = the energy of motion (moving, potential energy = stored energy (potential to move)
