Cytochrome c oxidase is the last enzyme in the respiratory
electron transport chain of mitochondria. It receives an electron
from each of four iron-containing cytochrome c molecules and
transfers the electrons to one oxygen molecule, converting
molecular oxygen to two molecules of water. In the last step of the
process, water is produced. The unbalanced equation for the redox
reaction is:
Fe2+(aq)+O2(aq)=Fe3+(aq)+H2O(l)
Write the balanced equation for the reaction under acidic conditions. Include charges and states where appropriate. Use the lowest whole-number coefficients possible.

The electron transport chain (ETC), or respiratory chain, is linked to proton movement and ATP synthesis. Select the statements that accurately describe the electron transport chain. Choose all that apply.Prosthetic groups, such as iron-sulfur centers, are directly involved with electron transfer. The reactions of the ETC take place in the outer membrane of mitochondria. Electron carriers in the mitochondrial matrix include ubiquinone (coenzyme Q), FMN, and cytochrome c. The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions. Electrons generated...

What is the function of cytochrome c in the electron
transport chain?
Question 3 of 4 To answer this question, you may reference the Metabolic Map. What is the function of cytochrome c in the electron transport chain? o It reduces two molecules of Q to QH2. It oxidizes NADH to NAD+. It oxidizes FADH2 to FAD. It transports two electrons from NADH or FADH to complex III. It transports an electron from complex III to complex IV.

Q13 Cyanide is a deadly poison that attaches to cytochrome c oxidase, the last protein in the electron transport chain before the terminal electron acceptor. Based on your knowledge of the electron transport chain, which statement below best describes the action of cyanide on the body? A. Cyanide does not allow the Krebs cycle to be completed by blocking acetyl CoA from entering this cycle. This action shuts down the entire process of cellular metabolism. B. Cyanide does not allow...

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...
