Biology- Anaerobic and Aerobic Respiration

Okay, these two types of respiration occur in the body, during exercise. Aerobic respiration needs oxygen (to release energy from glucose) but anaerobic does not, thus producing an oxygen debt. Alright, its equation time! Aerobic Respiration Glucose + Oxygen --> Carbon dioxide + Water + Released EnergyC6H6O6 + 6O2 --> 6CO2 + 6H20 + Energy Released>The energy released in aerobic respiration will always be more than the energy released in anaerobic respiration because this reaction is more efficient. Anaerobic Respiration Glucose--> Energy + Lactic Acid>Both reactions occurs in the mitochondria (this is an organelle of a cell) but in anaerobic respiration the lactic acid produced comes because of the lack of oxygen. Sounds cool huh? But there's just one problem...it's painful and it causes muscle fatigue! So how can we get it out of the body?!>We are going to need more oxygen to get into the body via the bloodstream which will produce the more harmless carbon dioxide + water that you will be familiar with from the aerobic respiration equation.>By breathing deeper and longer after exercise, we can get more oxygen into the body. *Symbols are important too- learn how to balance the equations, too!

This little heart of mine...is beating very fast... Extra carbon dioxide needs to be removed from the muscle cells, so we have to breathe faster to produce more oxidised blood. From the picture on the left, take the oxidised blood to be the red tube and the blood with loads of carbon dioxide to be the blue tube. For the body to meet the demand for more oxygen it:1. Makes you breathe deeper- so you inhale more oxygen at a time2. Makes your heart increase the speed at which it pumps.

Aerobic Respiration is used for many things... Well, obviously we need it for energy, but what exactly do we need this energy for?1.To turn small molecules into larger ones. (e.g. amino acids into proteins).2. To allow our muscles to contract so we can move. (lol imagine all that aerobic respiration and energy produced yet we can't even move to use it! haha) 3. In mammals and birds, energy helps keep their body temperature steady.4. In plants, energy is used to build sugars, nitrates and other nutrients into amino acids which later build up into proteins. Glycogen? Oh now I know this just sounds like wacky made-up words but actually, this is just what glucose is stored as in the body. >Sometimes (if we really love sports and we exercise reaaalllyyy hard), the glucose is used so rapidly during aerobic respiration that we need convert the glycogen back into glucose to provide more energy.Look at Serena Williams below, at times, she really be needin' some converted glycogen....
