FADH2 transfers its electrons into the electron
transport chain in the mitochondrion directly. to.
FADH2 transfers its electrons to succinate-Q reductase.
succinate-Q reductase is a complex consisting of succinate dehydrogenase and several iron-sulfur proteins.
By the electron transfer Fe2+ in succinate Q reductase reduces to Fe2+ .
FADH2 transfers its electrons into the electron transport chain in the mitochondrion directly. to.
What initiates electron transport chain? accumulation of pyruvic acid in mitochondrion formation of Actyl-CoA electrons delivered by coenzymes absence of oxygen
Regarding the electron transport chain (ETC)...How many ATPs are produced from one NADH? From one FADH2? Where in the ETC (i.e. to which electron carrier) does each of these molecules donate its electrons?
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
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
Question 5 (0.5 points) Where is the electron transport chain located? In the mitochondrial matrix In the mitochondrial outer membrane In the mitochondrial intermembrane space In the mitochondrial intermembrane Question 6 (0.5 points) What molecules release electrons into the electron transport chain? Acids Glucose and its metabolites NADH and FADH2 ADP
In the mitochondrion, where does the electron transport chain pump protons? a. from the matrix to the intermembrane space b. from the intermembrane space to the matrix c. from the cytosol to the intermembrane space d. from the intermembrane space to the cytosol e. from the cytosol to the matrix through membrane contact sites
Which electron carrier brings electrons to the electron transport chain via complex II? Which electron carrier brings electrons to the electron transport chain via Complex II? 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
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.
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...
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...
