Obligate aerobes require oxygen to produce ATP. Some cells can act as facultative anaerobes by supplementing their ATP with anaerobic pathways under low oxygen conditions, although oxygen is eventually needed for complete metabolism.
Los aerobios obligados requieren oxígeno para producir ATP. Algunas células pueden actuar como anaerobios facultativos complementando su ATP con vías anaeróbicas en condiciones de bajo oxígeno, aunque eventualmente el oxígeno es necesario para el metabolismo completo.
