Pregunta 13 de 16

1

During periods of intense exercise, cells do not receive enough oxygen to perform the normal process of aerobic cellular respiration. As a result, the cells resort to anaerobic respiration, which produces only 1/20th of the energy produced during the aerobic process. This alternative version of cellular respiration produces lactic acid as waste, which results in muscle soreness.
Which of the following statements does the above info support?

Selecciona una de las siguientes respuestas posibles:

  • Cellular respiration in affected by the availability of reactants

  • Cellular respiration in affected by temperature

  • Cellular respiration in affected by sugar production

  • Cellular respiration in affected by cell hydration

Explicación
