Systems that work to provide cells with glucose and oxygen for respiration
Digestive system
Lungs
Circulatory system
Aerobic respiration
An enzyme controlled reaction where the products glucose and oxygen react to form the waste products carbon dioxide and water, with energy transferred as a result
Aerobic respiration is an exothermic reaction because lots of energy is transferred to the surrounding environment whilst less is taken in
Aerobic respiration
Glucose + Oxygen -> Carbon Dioxide + Water + Energy transferred to the environment
Mitochondria are the site of aerobic respiration
Reasons why respiration is important
Synthesis reactions (building/creating molecules)
Muscle contraction
Maintaining internal body temperature
Plant growth (active transport + converting sugars and other minerals into amino acids for proteins)
Living cells need energy from respiration to carry out basic functions of life
Cytoplasm - where enzymes are made, locations of reactions in anaerobic respiration
Nucleus
Contains genetic material for enzymes involved in respiration
Mitochondria
Contains enzymes involved in respiration
Cell membrane
Allows gases and water to pass freely into and out of the cell
Controls the movement of other molecules (Glucose)
