In this experiment, the subjects of study were fermentation, mitochondrial respiration, and redox reactions in the first experiment, yeast was grown in various carbohydrate solutions at various temperatures. The anaerobic respiration yeast carries out is often called fermentation because it results in the production of alcohol baker’s yeast, not the same as winemaker’s or brewer’s yeast, can be bought fresh or dried.
Anaerobic respiration in yeast is used during brewing and bread-making: glucose → ethanol + carbon dioxide c 6 h 12 o 6 → 2c 2 h 5 oh + 2c0 2 ethanol is the alcohol found in alcoholic drinks like beer and wine in bread-making, bubbles of carbon dioxide gas expand the dough and help the bread rise. Fermentation is the breakdown of sugars by bacteria and yeast using a method of respiration without oxygen (anaerobic respiration) it involves a culture of yeast and a solution of sugar, producing ethanol and carbon dioxide with the aid of the enzymes all the enzymes are protein chains of amino acids.
