cellular respiration
Why do we do cellular respiration?cellular respiration:
The process of cell catabolism in which cells turn food into usable energy in the form of ATP |
GlycolysisThis happens in the cytoplasm just outside of the mitochondria. ATP supplies the energy needed to start the process of Glycolysis. Lactic Acid Fermentation happens in your muscles during exercise to help you get oxygen to the tissue fast enough.

krebs cycleThis is the cycle that comes after Glycolysis though only if there is oxygen present. This part of cellular respiration happens in the matrix of the mitochondria. Pyruvic acid enters the mitochandrion and joins with a Co Enzyme A to form Acetyl- Co A.
Carbon Dioxide is then released in to the air and high energy electron carriers move into the Electron Transport Chain. 2 Carbon ACETYL-COA combines with a 4 Carbon molecule to form a 6-Carbon molecule called Citric acid. Co Enzyme A goes back and picks up another Pyruvic acid and that completes the Krabs Cycle. |
electron transport chainAn electron transport chain couples electron transfer between an electron donor (such as NADH) and an electron acceptor (such as O2) with the transfer of H+ ions (protons) across a membrane. The resulting electrochemical proton gradient is used to generate chemical energy in the form of adenosine triphosphate(ATP). Electron transport chains are the cellular mechanisms used for extracting energy from sunlight in photosynthesis and also from redox reactions, such as the oxidation of sugars (respiration).

Fun facts
When Lactic acid builds up in your muscles, this causes the soreness you feel after exercise.
