BI 234 EXAM QUESTIONS WITH VERIFIED CORRECT
ANSWERS LATEST UPDATE GRADED A++
Photo
Energy from light
Chemo
Energy from Carbon dioxide, chemical compounds
photoautotrophs
Plants algea. use light as energy. Bring in to eat. dont have a carbon fixing
Chemoautotrophs
chemical energy source, aquire energy from redox reactions involving inorganic and
organic chemicals. Hydrogen, sulfur, nitrifying bactera. chemosynthesis make own
sugars, no light
Photo
redox reactions
composed of an electron orbiting simple nucleus.
Auto
Self making fixing carbon into glucose, same source
heter
eating different source
chemo
, glucose
heter
consume glucose
organotrophs
obtain electrons from organic compounds
Lithotrophs
use inorganic molecules as a source of electrons (granite, salt)
obligate aerobes
require oxygen, growth on top since most O2 is on top. not a final electon acceptor
Obligate Anaerobes
organisms that cannot live where molecular oxygen is present, will die in the presents of
oxygen, final electon acceptor
singlet oxygen
superoxide dismutase, enzyme converts into hydrogen peroxide and natural gas
superoxide radicals
toxic to cell, the cell use CO2 to efficiently and it denatures the cell. enzyme converts in
to hydrogen peroxide and natural gas
peroxide anion
metabolic reactions, peroxidase
hydroxyl radical
OH- does not get built up because there are preventions in place.
obligate anaerobes
no enzymes, antioxidants, ( keep you safe)
