Ecosystems
Aerobic respiration: Oxygen + Glucose -> Carbon dioxide + Water (+energy)
Breathing happens in the lungs, so gas exchange occurs
Respiration happens every cell in body, so we get energy
Mitochondria is where respiration takes place
Muscle cells have more mitochondria because they need lots of energy. But fat cells have less mitochondria because they need less energy
Glucose is absorbed by the wall of the small intestine into the blood stream. As it's transported around your body and dissolved so that it can diffuse into the cells that need respiration
Oxygen fills into your blood streams and is carried around by blood cells and when it reaches where it needs to go it diffuses into that cell
Carbon dioxide swaps with the oxygen so goes into the blood stream and then diffuses out and through the lungs, and then exhaled
A person suffering from starvation will: lack energy, die, keep bleeding when injured, lose weight, won't grow, easily injured, body shut down, be cold
Plants need energy because: to grow, make new cells, reproduce
Respiration: oxygen use to release energy from food
Energy: makes things happen
Aerobic: involves oxygen
Your brain is still awake and functioning and so we can breathe
Whereas respiration take place in the mitochondria
Aerobic meas involves oxygen. Anaerobic means not involving oxygen
Glucose -> Lactic Acid (+energy)
Aerobic respiration releases some energy, but not as much as aerobic respiration
Anaerobic respiration is a type of respiration that doesn't need oxygen
Anaerobic respiration produces lactic acid. This causes cramps
Glucose -> Ethanol + carbon dioxide + energy
