Respiratory pathway is

Step-by-step solution

Respiration is part of the metabolic process where the nutrients are converted into useful energy for regular cell activities. It is in two-mode depending on the presence or absence of oxygen. Aerobic respiration is the one where oxygen is involved and anaerobic respiration is the process where oxygen is absent. Respiration is generally considered catabolic as the complex compounds are broken into simpler forms to produce energy. Although, respiration has been found to be both catabolic and anabolic.
