HUMAN NUTRITION

Detailed explanation-1: -An important way of making ATP without oxygen is fermentation . There are two types of fermentation: alcoholic fermentation and lactic acid fermentationno post. Both start with glycolysis, the first (anaerobic) stage of cellular respiration, in which two molecules of ATP are produced from one molecule of glucose.

Detailed explanation-2: -The human body uses three types of molecules to yield the necessary energy to drive ATP synthesis: fats, proteins, and carbohydrates. Mitochondria are the main site for ATP synthesis in mammals, although some ATP is also synthesized in the cytoplasm.

Detailed explanation-3: -It produces lactic acid instead of carbon dioxide and water. This type of respiration is only used for short intervals. In the absence of oxygen, the process does not result in the development of any more ATP molecules.
