1. Interference of interruption of processes of cellular muscles can lead to twitting of muscles, muscle pulls and even cardiac arrest. Muscle pulls and cardiac arrest that be fatal if efforts are not made to restore the normal supply of oxygen that may be causing the muscle pull. Extreme cases of muscle pulls or cardiac arrest have resulted in death. As such, it is important to attend quickly to these sudden symptoms immediately they occur to avoid them turning fatal.
2. The oxygen that we inhale combines with the glucose at the cellular level through a process of oxidation of organic molecules in a process called aerobic respiration. Oxidation of oxygen and glucose results in the production of carbon dioxide exhaled, water, energy and heat.
3.
