when is co2 removed in cellular respiration
krebs cycle
what happens to the oxygen that is used in cellular respiration
oxygen accepts electrons and takes up protons to form water.
What is decarboxylation?
removal of CO2
what must happen to amino acids before they can be used in catabolic reactions?
undergo deamination to remove the amino group
fermentation (anaerobic respiration)
Process by which cells release energy in the absence of oxygen
Phosphofructokinase is
allosterically inhibited by ATP and/or citrate
how does glycolysis proceed in the absence of oxygen?
fermentation occurs
What stage of the cellular respiration can occur in human cells with or without oxygen present?
glycolysis
Remainder of the amino acid is converted to a molecule that enters
glycolysis or the Krebs cycle
