Cellular respiration is important to all organisms because it generates energy in the form of ATP, which is used by cells to carry out chemical reactions or metabolism. Find out how 36 ATP result from every broken down glucose molecule with help from a science teacher and field biologist in this free video on biology.

Hi I'm Brian with EricksonTutoring.blogspot.com. And today we're going to discuss how cellular respiration is important to all organisms. Respiration generates energy that in the form of ATP that is used by cells to carry out chemical reactions or metabolism. So it generates a lot of ATP, you get about 36 ATP for every glucose molecule that you break down. If you aren't able to go through the whole cycle so if you have anaerobic respiration, you only produce 2 ATP. So that's 34 ATP less per molecule, you're not getting a whole lot of energy out of that. The ultimate result and the reason that respiration is so important is because the energy that's created is used to carry out all sorts of different cellular processes that are essential to life as we know it. Without respiration, cells usually die and life turns over much more quickly. This has been a discussion of how cellular respiration is important to all organisms.
