EVERYDAY SCIENCE

Detailed explanation-1: -Cells need oxygen for the efficient use of glucose in cellular respiration. Most organisms use this method to obtain energy. Oxygen binds to parts of glucose molecules, which release water, carbon dioxide, and energy. After all, this is done, the organism uses the energy to produce adenosine triphosphate (ATP).

Detailed explanation-2: -Hint There are different type of cells present, it may be aerobic, the cells which require oxygen for producing the energy and for their survival, whereas the other one is called anaerobic, which do not require oxygen for the survival and producing the energy.

Detailed explanation-3: -Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.

Detailed explanation-4: -Muscle cells require the most ATP. Muscle cells are responsible for all of our movements. Most of the energy burned during the day is through the movement of the body by skeletal muscles. These muscles require large amounts of energy in order to perform the necessary mechanical work.
