Chapter 5 Study Guide
20
metabolism : the sum of all the chemical processes carried out by living organisms
anabolism : reactions that require energy to synthesize complex molecules from simpler ones
catabolism : reactions that release energy by breaking complex molecules into simpler ones that can be reused as building blocks
oxidation : loss or removal of electrons
reduction : gain of electrons
autotrophs : use carbon dioxide (inorganic substance) to synthesize organic molecules
photoautotrophs : obtain energy from light; photosynthetic bacteria
chemoautotrophs : obtain energy from oxidizing simple inorganic substances
heterotrophs : get their carbon from ready-made organic molecules, which they are obtained from other organisms
photoheterotrophs : obtain chemical energy from light; purple & green non-sulfur
chemoheterotrophs : obtain chemical energy from breaking down ready made organic compounds
anaerobes : organisms that do not use oxygen
gylcolysis : used by most autotrophic and heterotrophic organisms; both anaerobes and aerobes
fermentation : process by which pyretic acid is subsequently metabolized in the absence of oxygen
bioluminescence : ability to emit light
aerobes : organisms that do not use oxygen; they include some that must have oxygen
anaerobic respiration : inorganic oxygen-containing molecules such as nitrate
competitive inhibitor : competes with the substrate for the active site; non substrate
porins : transmembrane carrier proteins from channels through the outer membrane
PTS : consists of sugar-specific enzyme complexes call permeases ; transport system
pemeases : forms a transport system through the cell membrane
surfactant : lowers surface tension at eh bacterium's posterior end
