1)Where on the electron carrier Coenzyme Q are electrons "carried"?
2)Coenzyme Q and cytochrome C are similar in that they are both mobile electron carriers that act as part of the electron transport chain. However, they are different in most other ways. In one sentence for each, explain how they differ in their:
A) structural composition (i.e. what kinds of molecules are they?)
B) subcellular localization
C) electron-carrying capacity
Homework Answers
1. This is explained in the figure attached:
2. A. Composition: Coenzyme Q is an electron carrier and also organic and hydrophobic nature .
B) subcellular localization is presentin the lipid bilayer in soluble form of the mitochondrial inner membrane.
C) electron-carrying capacity :Its major function is to transfers two electrons between complex I or II and complex III of the electron transport chain.
it mainly carries two protons from the mitochondrial matrix to the intermembrane space.
A. Composition of Cytochrome c is a protein molecule with a heme prosthetic group & water soluble molecule.
B) subcellular localization is found in the inter-membrane space. It carries one electron from complex III to complex IV of the electron transport chain.

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.
Which of the following could explain why transfer of electrons from FADH2 to Coenzyme Q (CoQ)...
Which of the following could explain why transfer of electrons from FADH2 to Coenzyme Q (CoQ) is not coupled to proton transfer, but transfer from NADH to Coenzyme Q is? Select one: a. FADH2 donates more electrons than NADH to the electron transport chain. b. Because FADH2 has higher affinity for electrons than Coenzyme Q c. Because FADH2 is a higher energy carrier than NADH d. Because the transfer of electrons from FADH2 to CoQ does not release enough energy....

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...
