Cellular respiration

Hi Jacob! How was your school?
Very good mom, today in biology class, I learned about cellular respiration
Oh! and how does that work?
It's very easy mom, let me explain
And what is glycolysis about?
Look mom, cellular respiration is divided into 3 steps: Glycolysis, Krebs Cycle and Electron Transport Chain
Oh! You're right, I already remembered.
And where does glycolysis occur?
Glycolysis is a series of reactions that extract energy from glucose by breaking it down into two three-carbon molecules called pyruvate.
Glycolysis occurs in the cytosol of a cell.
Wow mom! You are so intelligent!
I remember that when I was your age, a teacher explained to me that the Krebs cycle is a set of reactions that occur in the mitochondria and that allow carbohydrates, lipids and amino acids to be completely oxidized, producing a large amount of metabolic energy.
And then the electrons pass from one member of the transport chain to the next in a series of redox reactions. The energy released in these reactions is captured as a proton gradient, which is in turn used to form ATP in a process called chemiosmosis.
this topic is very interesting!
And the last thing the teacher explained to us was the Electron transport chain, which is a series of proteins and organic molecules found in the inner membrane of the mitochondria...
