The equation of cellular respiration shows that when oxygen is by itself, it forms six carbon dioxide, six water and energy, which is the key component of the process. Discover how cellular respiration turns glucose into a usable form of energy with help from a science teacher and field biologist in this free video on chemistry.

Hi, I'm Brian with Ericksontutoring.blogscott, blogspot.com, and today we're going to discuss the equation for respiration. Cellular respiration is the process that, that cells go through to turn glucose into a form of usable energy, and that form would be ATP. So, the equation for cellular respiration is fairly straightforward if you know what the components are. For cellular respiration you have to have glucose, which is C6H12O6, that's just carbon, hydrogen and oxygen. And glucose plus oxygen, you have six of those, and oxygen is always O2 when it's by itself, forms six carbon dioxide, six water, and energy, which is the key component. One thing to note is that if we had this equation going the opposite direction and threw sunlight into the equation, we would be performing photosynthesis instead of cellular respiration. So, respiration essentially takes glucose, and turns it into a usable form of energy.
