This process is anaerobic (i.e., it does not require O2) inasmuch as it evolved before the accumulation of substantial amounts of oxygen in the atmosphere. Pyruvate can be further processed anaerobically (fermented) to lactate (lactic acid fermentation) or ethanol (alcoholic fermentation).
Does Glycogenesis require oxygen?
9c GLYCOGENESIS AND GLYCOGENOLYSIS-no oxygen needed. This is very important since tissues such as brain needs constant levels of glucose to produce ATP. ... Remember our body at this state must pump glucose into blood to keep the glucose levels at specific range.
What gluconeogenesis needs?
Gluconeogenesis supplies the needs for plasma glucose between meals. Gluconeogenesis is stimulated by the diabetogenic hormones (glucagon, growth hormone, epinephrine, and cortisol). Gluconeogenic substrates include glycerol, lactate, propionate, and certain amino acids.
