The character set used in preprocessor statements is the same as the execution character set. The preprocessor also recognizes negative character values. The preprocessor recognizes the following directives: #define. #error.
Not to be confused with Lactic acid fermentation. Anaerobic respiration is a form of respiration using electron acceptors other than oxygen. Although oxygen is not used as the final electron acceptor, the process still uses a respiratory electron transport chain; it is respiration without oxygen.In order for the electron transport chain to function, an exogenous final electron acceptor must be present to allow electrons to pass through the system.lthough oxygen is not used as the final electron acceptor, the process still uses a respiratory electron transport chain; it is respiration without oxygen.

However, internal respiration could be either aerobic or anaerobic. Aerobic respiration involves oxygen in the process, whereas there is no oxygen involved in anaerobic process. External Respiration. External respiration is the process of taking oxygen into and expelling carbon dioxide from the body.External respiration is essential for life as it supplies oxygen to extract energy from food via internal or cellular respiration. Additionally, it removes carbon dioxide, which is a waste product of respiration.owever, internal respiration could be either aerobic or anaerobic.
