Unformatted text preview: OLC IS PRODUCED TO RECEPTOR. IF ORG IS BY ITSELF, MOLEC IS TOO DILUTE AND WONT HIT RECEPTORS. IF LOTS OF ORG GROW IN CLOSE PROXIMITY, AND ALL PRODUCE MOLEC AND REACH THRESHOLD CONCENTRATION, IT WILL INTEREACT WILTH CELLR RECEPTOR AND SIGNAL CELL TO PRODUCE LIGHT. WASTE OF NRG TO GLOW IF SOLO, IF IN GROUP, BETTER BECAUSE GLOWING IS NOT FUNCTION (ATTACRT PREY) Chemoautotrophic medium: CO2 /CaCO3 NH4Cl S0/Fe+++/H2S/.. Mg/S/P/… Silicate (glass) Water C N energy minerals solidifier solvent Chemoautotrophs: IN ANAEROBIC RESP, SULFUR CAN BE USED AS TERMINAL ELEC ACCEPTOR. NH4/NH3 (reduced nitrogen)----> NO2- + ATP (Fe++ ---> Fe+++ // H2S --> S° //S°---> SO4=) SULFUR CYCLE: CHEMOAUTOTROPHS TAKE REDUCED FORM OF SULFUR, OXIDIZE IT AND PRODUCE NRG IN PROCESS. ORGANISMS THAT RESPIRE AEROBICALLY: USE OXIDIZED SULFUR AS TERMINAL ELECTRON ACCEPT IN ANAEROBIC RESPIRATION TO PRODUCE NRG. EX: IN MUDFLATS, SULFUR ODOR PRODUCED BY MO'S THAT PRODUCE H2S AND OTHER ORGS THAT OXIDIZE H2S NRG CAN BE HARV...
