Gas Exchange And Cellular Respiration
Gas Exchange
All living organisms respire and they need energy to carry out their life processes in order for organisms to survive and produce. The gases involved in cellular respiration is oxygen and carbon dioxide. The process of cellular respiration is releasing energy from sugars using oxygen and the product is carbon dioxide and water and in the process, ATP is made that can then be used for cellular work. Oxygen is needed to be absorbed from the environment and into the organism’s blood so it can be transported to respiring cells. Carbon dioxide must be released into the environment from the organism’s blood. The formula for cellular respiration is:
The exchange of gases essentially occurs as a result of diffusion down a concentration gradient. Gas exchange is essentially the diffusion of oxygen and carbon dioxide into and out of cells, and this is vital for respiration to occur.
Gas exchange is the getting oxygen from the lungs and …show more content…
Diffusion is the movement of particles from an area of high concentration to an area of low concentration until there is no longer a concentration gradient and the particles are all evenly distributed. For example- When there is a high concentration of oxygen in the air and a low concentration of oxygen in the blood, the high concentration of oxygen will move into the blood via diffusion until there is no longer a concentration gradient and the particles are all evenly distributed. There is a high to low or low to high concentration because of the gas exchange at the gas exchange surface. The reason for the low concentration is because the cell is using the oxygen in the air through respiration. Oxygen is inhaled and carbon dioxide is exhaled. Diffusion is a passive process which means that no energy is used to make the molecules move as they have natural kinetic energy. Diffusion through a cell membrane in mammals are called alveoli, in fish is called gills and in insects, are called
