Pregunta 2
Pregunta
ATP depletion is caused by [blank_start]hypoxia[blank_end] resulting in [blank_start]decreased[blank_end] oxidative posphorylation, [blank_start]decreased[blank_end] ATP, [blank_start]increased[blank_end] anaerobic glycolysis, [blank_start]decreased[blank_end] glycogen and decreased pH. the sodium potassium pump fails and ribosomes [blank_start]detach from[blank_end] the RER.
