BIOL240 Study Guide - Final Guide: Purple Sulfur Bacteria, Purple Bacteria, Green Sulfur Bacteria
Document Summary
Catabolism: breaking down molecules release of energy. Anabolism: building up molecules consumption of energy: example from class: he burned a leaf showing how microorganisms will take these electrons for their own functions such as powering their flagella. Macronutrients: are require by all cells to build macromolecules: c h o n p s. Micronutrients: required by some cells: most important is iron because it can fall under the macronutrient category. All life needs energy and carbon to make atp. Energy source: for oxidation to provide electrons for etc. Two types: light photosynthetic, chemical organic (glucose) or inorganic (h2, nh3, s, no2) Two types: fixed organic (c-c bonds) heterotroph eats others as a source of nutrients, gaseous inorganic (co2): autotroph self feeder. Chemolithotrops: energy from oxidation of inorganic compounds: found only in prokaryotes archaea and bacteria. Nutrient concentration: doesn"t matter what you provide the organisms with, they will always run out of some sort of macromolecule that they need.
