BTEC Level 3 Applied Science Unit10 Assignment B - RESPIRATION

Applied Science Unit10 Assignment B - RESPIRATION ntroduction to RespirationBreathing and respiration are two separate processes. Breathing is the process of moving air in and out of the lungs(inhalation and exhalation). Respiration is the process in all living organisms where energy, ATP, is produced in cells.ATP is adenosine triphosphate, which is a phosphorylated nucleotide with a similar structure to DNA and RNA. ATP isunable to leave the cell it was produced in. It occurs in the mitochondria, which are found in all animal cells. Themitochondria have two membranes, which are important as they allow the aerobic respiration reactions to beseparated from the rest of the cell. There are also enzymes which are important for the Link Reaction and KrebsCycle stages of respiration. These enzymes are housed in the matrix of the mitochondria. A large surface area isprovided by the cristae of the mitochondria, which is important as it allows for many Electron Transport Chains
