BI110 Lecture Notes - Lecture 16: Thermodynamics, Endomembrane System, Heterotroph
Document Summary
Requirements of the cell: a way to encode/transmit info. Dna & rna: a mem separating inside from out. Endomembrane system, membranes of organelles: energy!! Use energy to preform work form phosphate groups. Gain energy from sunlight: autotrophs (gathers carbon from inorganic sources, heterotroph (carbon from organic compounds, chemotrophs. Energy from chemical compounds: autotrophs (carbon from inorganic sources, like co2, heterotrophs (carbon from organic compounds, heterotrophs (carbon from organic compounds) The chemical rxns that convert molec into other molec and transfer energy into organisms. Catabolism: large macromolec into subunits & can create energy (atp) with adp + pi. Anabolism: from subunits to macromolec & uses atp. The capacity to do work: kinetic energy. A form of potential energy held in chemical bonds between pairs of atoms. Strong bonds have less potential energy than weak bonds. Strong is more likely to stay inert. Weak bonds contain a lot of chemical energy. It requires more energy to stay in tact.
