The scientist that was consider to be known as the "Father of Modern Chemistry" is Antoine Lavoisier
The answer is NAD+.
In the process of glycolysis, NAD+ is reduced to form NADH+ and H+. If NAD+ is not present, glycolysis will not be able to continue. Under anaerobic conditions, the regeneration of NAD is coupled to the reduction of pyruvate. The anaerobic regeneration of NAD is called fermentation.
In animal tissues , fermentation occurs as pyruvate acts as a makeshift hydrogen acceptor and gets reduced to lactate when NADH transfers electrons to pyruvate. This enzyme catalyzed reaction occurs whenever the available oxygen has been consumed.
First The meaning of sublimation is a chemical process where the solid change into a gas without going through the liquid stage.
The conditions necessary to occur are:
1- Need the pressure to be lower than the triple point.
2-The temperature must be high enough to produce a gas.
3-The substance must be in its solid state.
Not everything is used when it comes to food but everything is used with energy in the body!
