What cellular interactions are the result of their training, allowing for improved athletic performance? a) decreased muscle mass - increased proteins - decreased fat - glucose used for energy source b) increased muscle mass - increased mitochondria - increased cellular respiration - increased atp c) decreased mass - less energy needed for movement - less carbohydrates required - more available atp d) decreased respiration rate - increased oxygen consumption - increased cellular respiration - increased energy

The correct answer for this question is C) decreased mass - less energy needed for movement - less carbohydrates required - more available ATP

Solution; Increased muscle mass in athletes will increase the number of mitochondria in body. Mitochondria provides energy to cells of our body so more mitochondria will results in more energy and due to large amount of energy there will be increased cellular respiration and less fatigue, thus athletic performance will be improved.

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.
