1. When we (humans) exercise we need energy. Why do we need thisenergy? Where do we get this energy from? Certain tissues whichaccount for 40-50% of our body mass utilize a lot of energy and areespecially important in exercise. Describe indetail how the “energy†gets to this tissue and how it isutilized by this tissue during low and vigorous exercise. Whathappens when the tissue does not have enough “energy†and whenwould a situation like this occur?  Can we improve theamount of “energy†that this tissue gets? If we can how would youdo this when a person is at rest?
