The statement about isotonic exercise being classified as aerobic because it involves contraction without movement is not true. Isotonic exercises actually involve muscle contractions that result in movement, such as lifting weights or performing squats. This type of exercise can have both aerobic and anaerobic components, depending on the intensity and duration.

In contrast, the other statements are accurate. Increased heart rate does indeed enhance the transport of oxygen to working muscles, facilitating energy production during exercise. Furthermore, with increased cell respiration accompanying exercise, there is a rise in the production of ATP, heat, and carbon dioxide, all of which are byproducts of the metabolic processes that occur during physical activity. Additionally, increased respiration is crucial as it aids in expelling the excess carbon dioxide generated through metabolism, ensuring the body's pH level remains balanced.
