Glycolysis

Cellular respiration starts in the cytoplasm of a cell. Glucose from food is split in half by many enzymes to make 2 pyruvates. To make glycolysis happen, you need to use 2 ATP but once the glucose is broken, 4 ATP are made. There are 2 net ATP made in glycolysis

Krebs Cycle

The pyruvates move into the matrix of the mitochondria and there are split into H+ ions and CO2. The CO2 will be expelled as a waste product. The purpose of the Krebs Cycle is to produce electron carriers, NADH and FADH2. They carry the H+ ions.

Electron Transport Chain

The electron carriers, NADH and FADH2 carry the H+ ions to the cristae where they are pumped by protein pumps that force the ions into the intermembrane space.

ATP Synthase

Now, there is a high concentration of H+ ions in the intermembrane space. The O2 pulls the ions back towards the cristae and they go through the ATP synthase which attaches an ADP + P together to form ATP. The H+ ion then connects with O2 and forms H2O. The ATP Synthase then keeps joining the ADP and P together to make 32-36 ATP.
