Lactic acid fermentation is an anaerobic process. This means that lactic acid is produced in the absence of oxygen. This usually occur in bacteria cells but can also occur in muscle cells.
You breathe in fresh air which contains the oxygen you need. you get rid of carbon dioxide when you breathe out stale air
The fermentation of milk occurs to form curd, of course lactic acid is released.
Pyruvate+NADH--->Lactate + NAD+ +ATP
it makes the dough rise, and then the bread would be fluffier and would also taste better. hope this helps. :) XD
Howdy there!
Negative control for a fermentation lab should have the substrate in the vessel, and it should be very sterile so no contamination doesn't happen (make sure to label them vessels well). Secondly, the negative control vessel should not be inoculated with the microbe, like yeast, in it at all because you want no response. If there is a response, it could be contamination or you mistakenly inoculated with the microbe which fermented the substrate.
Hope this helped you plenty! 😄
Sugar from plant material is converted into ethanol and carbon dioxide by fermentation. The enzymes found in single-celled fungi (yeast) are the natural catalysts that can make this process happen: Unlike ethene, sugar from plant material is a renewable resource.
Phosphorylase is an enzyme which joins with Glucose-1-phosphate together to make larger starch molecules. it is an example of synthesis (a joing together enzyme)
There are three things. They are CO2,ethanol and ATP
Both alcoholic and lactic acid fermentation produce pyruvic acid (pyruvate), as an intermediate substance.
Simple answer:
Under the condition of strenuous exercise with inadequate oxygen supply. ;D
Complicated answer:
When your muscle cells are asked to perform work at an easy relaxed pace they take in glucose, fructose or sucrose plus oxygen from the blood, and using the "Aerobic Respiration" method, they generate cellular motion energy without releasing lactic acid.

http://en.wikipedia.org/wiki/Cellular_respiration#Aerobic_respiration
HOWEVER when your muscle cells are asked to perform strenuous work at an over-extended pace, (like your running away from a bear who wants to eat you). Then the oxygen becomes in short supply. There is not enough oxygen supplied by the lungs to increase output under the "Aerobic Respiration" method.
So, the muscle cells, knowing that they will die if they don't produce more energy, have a Plan - B. They can create massive amounts of energy without oxygen with the drawback of creating lactic acid. But that's fine, they will clean up that mess later. They start using an "Anaerobic Respiration" method.

The muscle prefers to make energy using "aerobic methods", but in extreme situations, your muscle cells have a "turbo" option: "Anaerobic_respiration".

Answer #2:
Your muscle cells will undergo lactic-acid fermentation (Creating cellular energy anaerobically) when there is not enough oxygen in the blood to create cellular energy in the preferred aerobic way.
It Builds up when you exersize and muscle cant get enough oxygen. its another way of creating energy.
you have to go get a job
and
go ask your science teacher to help
lactic acid fermentation helps make yogurt, cheese, and it also occurs in muscles which is why you may get that burning sensation in your legs while excersizing. Alcoholic fermentation makes wine and bread using yeast.
The similarity is they both will make ATP (energy) as a product though the alcohol fermentation makes very less.
Creatine phosphate is a better source of quick energy than glucose because in thermodynamic scale of energy potential Creatine phosphate is a super high energy phosphate compounds which has higher standard free energy of hydrolysis than that of ATP and can give its high energy phosphoryl group to ADP to generate ATP which is used to biosynthesis Glucose. so creatine phosphate stored in muscle is quick enery source to produce ATP than glucoe.
We would die because are body would not be making ATP and are body's could not hold down yeast
An organic acid with the chemical formula CH3CH (OH). COOH. Lactic acid is a product of anaerobic glycolysisLactic acid system An anaerobic energy system in which ATP is manufactured from the breakdown of glucose to pyruvic acid. The acid is then converted to lactic acid. High-intensity activities lasting up to about two or three min use this energy system during which the reduction of nicotinamide adenine dinucleotide (NAD) is coupled with a net production of two ATP molecules for each glucose molecule metabolized.
The process of fermentation releases carbon dioxide, so we can not stay in fermentation forever.
while respiration implies air, fermentation is an anaerobic (no oxygen) process.
Fermentation is a chemical process.
Using the Henderson-Hasslebach equation, pH=pKa+log([base]/[acid]), we can determine the pH as follows:
pH=4.4+log([0.8]/[0.2])
pH=4.4+log(4)
pH=4.4+0.60
pH=5.0
