Describe lactic acid fermentation and alcoholic fermentation. Alcohol fermentation Lactic acid fermentation occurs in bacteria, fungi, and animal muscle cells. Alcoholic fermentation which is also called as ethanol fermentation is a biological process in which sugars such as glucose, fructose, and sucrose into are converted into cellular energy, producing ethanol and carbon dioxide as by-products. • What is the role of the citric acid cycle? Copy the picture of its molecular formula, copy the web page address and put it next to the picture. The energy produced : Two molecules of ATP which are not enough to perform all the vital activities … How is cellular respiration like combustion (burning)? through the acetyl co-A formation stage. Anaerobic respiration begins the same way as aerobic respiration and fermentation. Glycolysis followed by fermentation produces much less ATP than aerobic cellular respiration, but fermentation is very useful when oxygen is not available. Abstract

Alcoholic fermentation is the best known of the fermentation processes, and is involved in several important transformation, stabilization, and conservation processes for sugar-rich substrates, such as fruit, and fruit and vegetable juices. It's a pretty simple follow-up to glycolysis: the pyruvate molecules are reduced to lactate, while NADH is oxidized to NAD +. Alcoholic fermentation is the best known of the fermentation processes, and is involved in several important transformation, stabilization, and conservation processes for sugar-rich substrates, such as fruit, and fruit and vegetable juices. Both types of fermentation occur in the cytosol. Aerobic pathways require oxygen, while anaerobic pathways don't.

Yeast consume the sugar in wort, and turn that sugar into CO2, alcohol, and flavor. Respiration is the most common energy yielding process in all organisms; the prerequisite being the presence of oxygen, and hence, referred to as aerobic cellular respiration. 2. Through the process of aerobic respiration, living things break down glucose to create ATP. Julius Engel; Section 8
