Oxygen must be absent in the cell.
Fermentation can occur anytime you have yeast, sugar and a fairly constant temperature. Oxygen doesn't necessarily prevent fermentation, but it can increase the chances of bacteria contamination, which does ugly things to flavors.
Moonshine is often fermented in large open vats.
For a cell to engage in fermentation there should be no or few oxygen molecules present . An anaerobic situation where oxygen is not being consumed in as sufficient quantities to keep up with oxygen used.
When a cell does not have enough oxygen for respiration is when fermentation occurs.
oxygen must be absent in the cell.
Oxygen must be absent in the cell.
low oxygen
It makes energy for a cell.
Fermentation occurs in the Cytosol (cytoplasm), without oxygen.
oxygen
Cellular respiration and fermentation are two different processes.
Low or no oxygen.
Cytoplasm, because it is an anerobic respiration, and does not require O2, so it does not occur in the mitochondira.
low oxygen
Fermentation assures a supply of NAD+ and NADP+ for glycolysis; glycolysis is where ATP is synthesized during fermentation and ATP is essential for cell life.
A heterozygous condition.
