(A) Aerobic respiration is a process in which the food glucose is converted into energy in the presence of oxygen. The general equation of aerobic respiration as a whole is as given below-
Glucose + oxygen ==Carbon-dioxide+ Water+ Energy
In the above equation, energy is released by the breaking up of glucose by oxygen and as a result of this, the water and the carbon-dioxide are being produced as one of the resultant of the reaction. When one molecule of glucose is broken, 2900 kJ of energy is released. This is used in-turn to create a new type of energy molecule called as the ATP of the Adenosine Triphosphate. The body uses this ATP generated as the energy for various purposes.
Aerobic respiration process also takes place in animals, plants and other living organisms. Firstly the oxygen enters the cells of plants with the help of stomata. Plants produce their food with the aid of photosynthesis process and thus release energy from it through the respiration process. The below equation describes the process of photosynthesis or the aerobic respiration in plants.
Carbon-dioxide + water== Glucose + Oxygen

Carbon monoxide (CO) is a gas that has no odor or color. But it is very dangerous. It can cause sudden illness and death. CO is found in combustion fumes, such as those made by cars and trucks, lanterns, stoves, gas ranges and heating systems. CO from these fumes can build up in places that don't have a good flow of fresh air. You can be poisoned by breathing them in. The most common symptoms of CO poisoning are
Headache
Dizziness
Weakness
Nausea
Vomiting
Chest pain
Confusion
It is often hard to tell if someone has CO poisoning, because the symptoms may be like those of other illnesses. People who are sleeping or intoxicated can die from CO poisoning before they have symptoms. A CO detector can warn you if you have high levels of CO in your home.
