Detailed explanation-1: -Hint: The type of respiration where energy is generated by the breakdown of the sugar molecules in the absence of oxygen is called anaerobic respiration. The metabolic process that extracts energy from the carbohydrates by the action of enzymes in the absence of oxygen is called fermentation.

Detailed explanation-2: -Anaerobic respiration is a type of respiration that allows cells to break down sugars for energy production without the use of oxygen. Anaerobic fermentation is a chemical process in which molecules such as glucose are broken down without the use of oxygen.

Detailed explanation-3: -Anaerobic respiration is the formation of ATP without oxygen. This method still incorporates the respiratory electron transport chain, but without using oxygen as the terminal electron acceptor.

Detailed explanation-4: -Fermentation does not involve an electron transport chain and does not directly produce any additional ATP beyond that produced during glycolysis by substrate-level phosphorylation. Organisms carrying out fermentation typically produce a maximum of two ATP molecules per glucose during glycolysis.
