FADH_2 FAD NADH NAD^+ Which electron carrier brings electrons to the electron transport chain via Complex I? FADH_2 FAD NADH NAD^+ As the electron transport chain proceeds, electrons H^+ ions water CO_2 molecules are pumped into the intermembrane space cytoplasm matrix nucleus
Question 9 1 pts In the reaction occurring at the start of the electron transport chain: (NADH dehydrogenase is also known as Complex I) NADH NAD+ + H+ NADH dehydrogenase O NADH is reduced, NADH dehydrogenase is oxidized O NADH dehyrogenase removes a H from NADH, but does not accept electrons O NADH is oxidized, NADH dehyrogenase is reduced NAD+ is reduced, NADH is oxidized
C. Considering Electron Transport: In LA3 Video 3, we are considering electron transport and oxidative phosphorylation. Please answer the following multiple choice questions (0.5 pts each) and follow instructions for two final drawings (2 pts each). 1. The electrons involved in electron transport come from (A) glycolysis (B) the pyruvate dehydrogenase complex (C) the citric acid cycle (D) all three processes 2. When NADH and FADH2 transfer their electrons to the electron transport chain, they are (A) oxidized (B) epimerized...
Fill in the blanks regarding the electron transport chain and oxidative phosphorylation. Complex1 accepts electrons from NADH and uses coenzyme Q to transport them to complex 3. Complex 2 accepts electrons from FADH2 and uses coenzyme q to transport them from complex 3 to complex 4. The ATP synthase will transport 3H+ ions for every 2 ATP produces. This entire process occurs across the inner mitochondrial membrane. Fill in the blanks regarding the electron transport chain and oxidative phosphorylation
High-energy electrons from molecules of NADH and FADH2 are transferred to a chain of proteins within the electron transport chain. What is the final protein in the electron transport chain? O cytochromec oxygen O carbon dioxide NAD+ ubiquinone
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.
1. Select the TRUE statement about the component of the electron transport chain. A. Complex III is a peripheral membrane protein B. Cytochrome c is a lipid-linked protein C. Complex II is a transmembrane protein D. Complex I is an integral membrane protein E. Complex IV is not a transmembrane protein 2. The rate of oxygen consumption at the inner mitochondrial membrane is related to all the following EXCEPT: A. Availability of ADP in the mitochondria B. The rate of...
1 point As you know all the intermediates in the electron transport chain receive electrons from one complex or clectron transporters, become reduced, and then transfer these electron to the next complex or transporter. What would you expect if you have a physiological condition where Oz is abundant, but NADH and FADHz are exhausted lots of oxygen but no NADH or FADH. O Complex and I will be reduced. Complex Ill and I will be oxidized O All of the...
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...
