Comic strips for my Biology Semester 2 KA #1 on "Cellular Energy." Comic strips using terms that are found throughout cellular respiration.
Cellular respiration (C6H12O6 + 6O2 → 6CO2 + 6 H2O + energy (ATP + heat)), mostly occurs within the mitochondria and has three stages.
Glycolysis is a process in cellular respiration that occurs in the cytoplasm outside of the mitochondria.
The starting material for glycolysis, glucose, is broken down and separated to form 2 pyruvates, net 2 ATP + 2 NADH.
The next two processes, Krebs cycle and Electron transport chain, will only occur if oxygen is present, and if so, will take place within the mitochondria.
The Krebs cycle takes place within the mitochondrial matrix. It’s products include 6 carbon dioxide molecules, 8 NADH, 2 FADH2, and 2 ATP.
Finally, the ETC (Electron Transport Chain) will combine oxygen molecules and hydrogen molecules (hydrogen from the 8 NADH and FADH2) to create water and over 30 ATP. This process occurs in the inner membrane of the mitochondria.
