Cellular Respiration Overview Animation with Glycolysis, Krebs, and ETC

This is a primer to give you the big picture of what happens during Cellular Respiration. To see detailed animations of each part, look at these: Glycolysis http://www.youtube.com/watch?v=x-stLxqPt6E The Krebs Cycle (Citric Acid Cycle) http://www.youtube.com/watch?v=aCypoN3X7KQ Electron Transport Chain (Chemiosmosis) http://www.youtube.com/watch?v=Idy2XAlZIVA Animals need energy to carry out the functions of life. Taking the products of plants (Oxygen and Glucose), along with water, we create what the plants need (Carbon Dioxide) to live. At the same time, this beautifully designed system provides animals, like we humans, with all the energy necessary for life.

ATP is how we store and use energy, think of it as the cells currency. Whenever the body needs something it "buys" it with some ATP. ATP is a molecule call Adenine (adenosine once phosphates attach) with three phosphate molecules attached. Picture a kite(adenosine) with 3 big bows(phosphates) attached to the tail. The bond between the second and third phosphate is considered a high energy bond. When that third phosphate is broken off a lot of energy is available. When this happens ATP becomes ADP (Adenosine DiPhosphate). Cellular Respiration is the process the body uses to make ADP into spendable ATP once again. Glucose, a sugar, has a chemical shape of many elements such as carbon, oxygen, and hydrogen. Inside our cells glucose is changed many times over as it is broken down by the body. This happens just out side and mainly inside an organelle called the mitochondria. Every element has protons and electrons, as the body breaks down sugar it will separate the electrons from the protons to use them to make a lot of ATP. Try to pay attention to two main things.. 1. What are the carbon doing? How many are there? Follow the black circles(carbon) and you will really start to get this process quicker. 2. Where are the electrons going? How are they getting there? What is carrying them there? Electrons carry most of the power that will eventually make the ATP in the end. *Anaerobic Respiration/Fermentation can be seen here: http://www.youtube.com/watch?v=y_k8xLrBUfg Some Related Videos...
