Two substances in the body that will move based on the principle of diffusion are CARBON DIOXIDE AND OXYGEN.
Diffusion is the process by which molecules of a substance move from the region of higher concentration to the region of lower concentration. Carbon dioxide and oxygen can easily move in an out of the cell via diffusion.<span />
Answer:
Fats and ATP are both energy molecules.
ATP is the source of energy which is directly used by each cell to carry out different functions. All cells use energy in the form of ATP. The mitochondria makes ATP by the process of cellular respiration whenever it is required by the body. ATP is not a stable molecule hence energy cannot be stored in this form.
Fats are long term energy storage molecules. Fats are stable molecules hence they can be used for long term energy storage.
Answer : The Aerobic exercise improves the oxygen purifying capacity of lungs. So, one can breathe in more oxygen through inhalation and then more oxygen is transferred to muscles in the body, also carbon dioxide is given actively out of the body through exhalation. All these gives body more energy to perform daily tasks and stay fit and healthy.
