This question relates to complex III of the electron transport chain Identify the electron carrier that directly donates electrons to complex III and the electron carrier that ultimately receives electrons from complex III 1^st (donating) carrier: _________ 2^nd (receiving) carrier: _______ How much energy is released by transferring one pair of electrons from the donating electron carrier to the receiving electron carrier? How many protons are transferred out of the intermembrane space as a transferring one pair of electrons from...
QUESTION 4 You are studying an electron transport chain from a newly identified life form that has four electron carriers, a, b, c, and d. They function in the following order: substrate → → → → → 02 Three compounds are identified which inhibit this newly discovered electron transport chain in the presence of substrate and oxygen, yielding the patterns of oxidation states shown below. O and R indicate fully oxidized and fully reduced, respectively. Inhibitor ROOO Z o substrate...
why is it important for the function of the mitochondrial electron transport chain for the value of E of cytochrome c to fall between 0.22 and 0.29V
The electron transport chain eases the fall of electrons to the terminal oxygen. Why is this important?
Cyanide is a deadly and notorious poison that inhibits the electron transport chain by competitively inhibiting cytochorome c oxidase. Given this information answer the following questions: Cyanide inhibition of the electron transport chain will __________ (simply state raise or lower) ATP production. Cyanide inhibition of the electron transport chain will __________ (simply state raise or lower) NAD+ levels in the mitochondria. Cyanide inhibition of the electron transport chain will __________ (simply state raise of lower) NADH levels in the mitochondria....
The electron transport chain consists of protein complexes embedded in the inner mitochondrial membrane, where it generat a proton gradient by a series of oxidation-reduction, or redox, reactions. Although all of the stages of cellular respiration (glycolysis, the citric acid cycle, and the electron transport chain) are necessary for life, the electron transport chain is sometimes called the most important stage. First complete the sentence, then answer the question. The electron transport chain uses the transfer of protons between protein...
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. Electron transfer in the ETC is coupled to proton transfer from the matrix to the intermembrane space The outer membrane of mitochondria is readily permeable to small molecules and hydrogen ions. Prosthetic groups, such as iron-sulfur centers, are directly involved with electron transfer. Electron carriers in the ETC include ubiquinone...
What happens along an electron transport chain? What happens along an electron transport chain? Electrons are passed from a reducing agent to an oxidizing agent, releasing free energy at each step. Electrons are passed from molecule to molecule, gaining potential energy at each step. O Electrons store energy that can be used to break down sugar molecules. O Protons are pumped through ATP synthase, making ATP.
