A. The individual’s ATP production will decrease significantly
B. The individual’s ATP production will increase significantly
C. The individual’s ATP production will not change significantly
(C) The individual’s ATP production will not change significantly. Going eight hours without food will only make small changes in ATP production for a healthy individual. Hence, the body's ATP production and energy supply will be affected significantly only if healthy individuals fast for a longer period.
С healthy individual’s ATP production will not change significantly during an eight-hour fast. Eight hours is not long enough to influence an individual’s energy supply. There are three processes of ATP production: glycolysis, the tricarboxylic acid cycle, and oxidation phosphorylation.
B. the individual's ATP production will increase significantly. An important source of energy needed for muscle contraction. They are kept in much amount in the body but release first when needed. During vigorous and long hour exercise, ATP is needed urgently by muscles. Muscle cells have many ways of making ATP energy by using glycogen, aerobic type of respiration, and creatine phosphate called biochemical systems.
