Homework Answers
One carrier molecule in the electron transport chain called the flavoprotein can bypass the next carrier in the chain and transfer electrons directly to oxygen. This alternative pathway produces two high potent cellular toxins HYDROGEN PEROXIDE (H2O2) AND SUPEROXIDE RADICAL (O2-).
These toxins are the by products of the system.
We cannot control their production. For more details on how these are produced, we need to study the ETC.

Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...
