Global balance of cellular respiration

In this video I will explain what is the energy balance of cellular respiration.

Let's get to know the energy balance of cellular respiration. We will focus on aerobic cellular respiration, although it would be very similar to the energy balance of anaerobic respiration.

Respiration is divided into three stages:

• 1. Glycolysis: transformation of a glucose into two pyruvates. It is a decomposition reaction. 1 element becomes 2 less energetic elements.
• 2. Krebs cycle: transformation of the 2 pyruvates to acetyl-coa.
• 3. Oxidative phosphorylation: In this phase, thanks to the energy saved from the previous steps, we burn carbon dioxide.

RESULT: 36-38 ATP (depends on NADH used to dehydrogenate pyruvate).

It is very important that this process be carried out in order to burn any molecule that we ingest.

In the video you will be able to understand better the energy balance of cellular respiration. In addition, if you are not sure you can continue practicing with problems of this type you can do the printable exercises with their solutions that I have left you on the web. Good luck in your studies!
