Cell Respiration by Molly Stewart

Glycolysis

Glycolysis takes place in the cytoplasm of a cell and splits a molecule of glucose into 2 pryuvate molecules. This process requires 2 ATP molecules to start and produces 4 ATP leading to a net gain of 2 ATP.

Krebs Cycle

The Krebs Cycle takes place in the mitochondria matrix and uses the 2 pryuvate from the previous step glycolysis. The Krebs Cycle then uses the 2 pryuvate to make another 2 ATP, 6CO₂ which is expelled as a waste product as well as 6NADH, 2FADH₂which are electron carriers delivering electrons to the ECT.

Electron Transport Chain

The Electron Transport Chain (ECT) takes place in the cristae of the mitochondria. The ECT uses the 6NADH and the 2FADH₂ to get H+ electrons which then bond with O₂ to make H2O or move on to the next step.

ATP Synthase

ATP Synthase is the final step of cellular respiration where the majority of the ATP is made. ATP synthase takes the H+ from the ETC, lets them back in and ultimately creates 32 ATP. After the final step when all's said and done there are 36 ATP molecules from the 4 steps of cellular respiration.
