Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format. A 67-year-old patient with severe sepsis undergoes a full infectious workup upon admittance to the intensive care unit. Cultures of urine, blood, sputum, and cerebral spinal fluid are obtained. The cultures do not yield a specific organism, so further analysis of the sample is done to determine the characteristics of the microorganism. The metabolic processes are analyzed in the lab. -The organism sample is further tested and found to grow in the absence of oxygen.Which of three main pathways of catabolism may this organism utilize to produce energy in the absence of free oxygen?
