Although, some animals use anaerobic metabolism, in which food molecules are oxidized incompletely to lactic acid, lactate (Randall et al., 2002). There are particular times when animals cannot use aerobic metabolism for their energy needs. Such times include when oxygen is low in the environment. Also, when animals exercise, their increase in muscle contraction raises ATP demand resulting in the capacity for oxygen delivery
