Let’s consider a simple chemical reaction involving the combustion of methane (CH₄) in oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O). The balanced chemical equation for this reaction is:Methane + Oxygen → Carbon Dioxide + Water
To understand this reaction better, we can analyze the masses of the reactants and products involved:

Functions of RBC : transport around the body
One of the key functions of blood is transport. Blood
vessels are like networks of roads where deliveries and waste removal take
place. Oxygen, nutrients and hormones are delivered around the body in the
blood and carbon dioxide and other waste products are removed.
The heart is constantly pumping blood so it is always moving around the body.
Transporting oxygen is a vital role of the red blood
cells.
When we breathe in, the millions of air sacs in the
lungs fill with fresh oxygenated air. The oxygen then moves into the blood by
passing first through the very thin walls of the air sacs and then into the
capillaries, which are tiny blood vessels in a network within the lungs.
Red blood cells squeeze through
narrow capillaries in single file. Haemoglobin molecules inside red blood cells
pick up and carry the oxygen. These oxygen-rich cells travel in the blood
vessels from the lungs to the left side of the heart. The blood is then pumped
around the body.
Red blood cells are adapted for the transport of
oxygen. They are small and flexible so they can fit through narrow vessels,
have a bi-concave shape which maximises their surface area to absorb oxygen,
have a thin membrane so gases easily diffuse through, and contain haemoglobin
which binds to oxygen.
Glucose and oxygen react together in cells to produce carbon dioxide and water and release energy.
Here is the word equation for aerobic respiration:
glucose + oxygen → carbon dioxide + water + energy
This is called AEROBIC Respiration – because it needs oxygen from air for it to work
The source of the energy required to regenerate ATP is the chemical energy stored in food (e.g. glucose). The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called . Some of the energy released is used to produce ATP. Some of the energy released is lost as heat.
Mammals need to release heat energy from food to keep their body temperature close to the optimum operating temperature for their enzymes.
There are two types of respiration. Aerobic respiration occurs if oxygen is present in the cell. occurs if oxygen is absent.
The following is a summary word equation for aerobic respiration.
