BiologyCommunication, homeostasis and energy (F214)A2/A-levelOCR Created by: rae97Created on: 18-03-15 16:47 Autotroph An organism that uses light energy or chemical energy and inorganic molecules to synthesise complex organic molecules 1 of 9 Heterotroph Organisms that ingest and digest complex organic molecules, releasing the chemical potential energy stored in them 2 of 9 Nanometre (nm) one thousandth of a micrometre, or one millionth of a millimetre 3 of 9 Photosynthestic pigment Molecules that absorb light energy. Each pigment absorbs a particular wavelength and all others are reflected 4 of 9 Photophosphorylation The making of ATP from ADP and Pi in the presence of light 5 of 9 Electron carriers Molecules that transfer electrons 6 of 9 Electron acceptors Chemicals that accept electrons from another compound. They are reduced while acting as oxidising agents 7 of 9 Light-independent stage Where carbon dioxide is fixed and used to build complex organic molecules 8 of 9 What is the limiting factor for a metabolic process? The factor that is present at the lowest or least favourable value 9 of 9
