You are out on a leisurely walk with your dog. Suddenly, the dog runs off toward a traffic filled street. Worried that it might get run over, you sprint after it. Luckily, you catch it before anything happens, but you find yourself panting. Later, your leg muscles ache a little.

Describe the types of cellular respiration your body cells carry out on the event.

While you are leisurely walking, your body cells are performing aerobic respiration. Aerobic respiration is the process where in the cells (primarily in mitochondria) converts glucose into energy via series of chemical reaction. This happens when there in the presence of enough oxygen in your cells. Apparently, as you walk, the oxygen levels may increase or decrease depending on the stress of your action. As you run towards your dog to save its life, you exert much more effort thus your cells consume oxygen at a much faster rate, eventually decreasing the levels of oxygen available to your cells. Your body cells will now shift to the anaerobic respiration which converts glucose into energy and consequently, your cells will produce lactate that will cause your muscles to ache.  Also, anaerobic respiration is an inefficient way to produce energy compared with aerobic respiration.

Aerobic respiration = converts 1 mole glucose to 36 moles ATP

Anaerobic respiration = converts 1 mole of glucose to 2 moles ATP
