Reaction of anaerobic respiration in yeast
WebDuring anaerobic respiration, yeast cells convert glucose into energy through a series of chemical reactions known as glycolysis. This process begins with the breakdown of … WebIn yeast anaerobic respiration may be summarised by: glucose ethanol + carbon dioxide + energy During glycolysis, glucose molecules (six-carbon molecules) are split into two pyruvates (three-carbon molecules) during a sequence of enzyme-controlled reactions. This is the same reaction as occurs in aerobic respiration.

WebThe five reactions of this phase are as follows; In the first reaction, glucose is phosphorylated to form glucose-6-phosphate. This is done by a family of enzymes called hexokinases. Hexokinase I-III can phosphorylate any hexose sugar while Hexokinase IV is highly specific for glucose. It is also known as glucokinase. WebAnaerobic respiration is useful in generating electricity in microbial fuel cells, which employ bacteria that respire solid electron acceptors (such as oxidized iron) to transfer electrons from reduced compounds to an electrode. This process can simultaneously degrade organic carbon waste and generate electricity. [8]
