Bakeries use the process of fermentation for preparing bread, biscuits and cakes.Most of the industries use them for the following purposes: They culture micro-organisms in very large numbers. Q1: Describe the significance of fermentation.Īns: Fermentation process is very important in industries. The fermentation process is used in our daily life such as in the formation of curd, vinegar, bread and alcoholic drinks. Both these process are hazardous because they produce alcohol or acid during the process.
NADH +H + is the reducing agent which oxidises to NAD + in the process.īoth alcohol and lactic acid fermentation release very less energy. In animal cells as well, during muscle exercise, in case of inadequacy of oxygen for cellular respiration, pyruvic acid reduces to lactic acid by lactate dehydrogenase. Other organisms such as bacteria produce lactic acid from pyruvic acid. They are alcohol dehydrogenase and acid-decarboxylase. In these reactions, pyruvic acid converts into ethanol and carbon dioxide. this process takes place under anaerobic conditions via a set of reactions. In this process, the plants carry out the incomplete oxidation of glucose. Aerobic Respiration and Respiratory Quotient.Browse more Topics under Respiration In Plants Now, we move on to the next concept of fermentation. The fructose-1, 6-diphosphate is broken into two compounds which are isomers of each other. During the conversion of fructose-6-phosphate in fructose 1 and 6-diphosphate.During the conversion of glucose into glucose-6-phosphate.In this process, a chain of ten reactions takes place under the control of various enzymes and the outcome is pyruvate.ĪTP is utilized in two steps of Glycolysis: We have shown the steps of Glycolysis in the figure below. This phosphorylated glucose isomerizes to produce fructose-6-phosphate. Glucose and fructose are phosphorylated to give rise to glucose-6-phosphate via enzyme hexokinase. This results in two molecules of pyruvic acid. Here, the plants carry out the partial oxidation of glucose. This process takes place in the cytoplasm of the cells. In case of anaerobic respiration, plants carry out respiration via glycolysis. Parnas and Gustav were the first ones to give the scheme of glycolysis. Glycos which means sugar and lysis means splitting. Glycolysis gets its name from two Greek words, i.e.
