Respiration
2
TermDefinition MetabolismThe chemical processes that occur within a living organism in order to maintain life: AnabolismA metabolic process in which complex molecules are synthesized from simpler ones with the storage of energy CatabolismThe breaking down in living organisms of more complex substances into simpler ones, with the release of energy Aerobic respirationThe production of ATP from the breakdown of food compounds requiring oxygen. Anaerobic respirationThe production of ATP from the breakdown of food compounds without the requirement for oxygen

PartFeatures Outer membraneHas lots of protein channels to allow pyruvate to enter Inner membraneCarries ATP synthase and ETC proteins. Is impermeable to tiny particles- Protons Intermembrane spaceIs narrow so a high concentration of protons can build up MatrixContains enzymes for Link reaction and Kreb`s cycle Ribosomes-70SSite of protein synthesis Mitochondrial DNACarries some genes Mitochondria
5
Cells require energy to perform vital activities such as: Active transport Protein synthesis Cell division Muscle contraction
8
Facts about ATP For each mole of ATP broken down 30.6 KJ of energy is released. We only have enough ATP stored up in our bodies for a few seconds of activity ATP gets used up fairly quickly by the body. Each ATP molecule is recycled about 1500 times a day
