Answer:
If respiration fails to occur, cells and tissues will start to die due to a lack of oxygen.
Explanation:
Cellular respiration is a metabolic process that cells use to reduce oxygen and produce energy and water. Without respiration, cells will switch to using pyruvate or a pyruvate-derived molecule as an electron acceptor for the regeneration of NAD+, which is called fermentation. This can cause the cells to die.
