What is the role of NADH and FADH2 in the electron transport chain?
NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain. FADH2: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.
What is the role of NADH and FADH2 in the electron transport chain quizlet?
The role of NADH and FADH2 is to donate electrons to the electron transport chain. They both donate electrons by providing an hydrogen molecule to the oxygen molecule to create water during the electron transport chain. NADH is a product of both the glycolysis and Kreb cycles. FADH2 is only produced in Krebs cycle.
Does electron transport chain require FADH2?
The events of the electron transport chain involve NADH and FADH, which act as electron transporters as they flow through the inner membrane space. The movement of electrons through complexes I-IV causes protons (hydrogen atoms) to be pumped out of the intermembrane space into the cell cytosol.
What do NADH and FADH2 deliver to electron transfer chains quizlet?
The NADH and FADH2 deliver their electrons to the electron transport chain (E.T.C.), being oxidized back to NAD+ and FAD and ready for reuse. The four Protein Complexes use the energy from NADH/FADH2 to pump protons (H+ ions) from the mitochondrial matrix into the intermembrane space.
What is the difference between FADH2 and NADH in the electron transport chain?
The main difference between NADH and FADH2 is that every NADH molecule produces 3 ATP molecules during oxidative phosphorylation whereas every FADH2 molecule produces 2 ATP molecules. Furthermore, NADH transfers electrons to Cytochrome complex I while FADH2 transfers electrons to Cytochrome complex II.
Is NADH an electron carrier?
NADH is the reduced form of the electron carrier, and NADH is converted into NAD+. This half of the reaction results in the oxidation of the electron carrier.
What is the main function of the electron transport chain quizlet?
The main purpose of the electron transport chain is to build up a surplus of hydrogen ions (protons) in the intermembrane space sp that there will be a concentration gradient compared to the matrix of the mitochondria. This will drive ATP synthase.
What is the function of ATP synthase in the electron transport chain?
During electron transport, the participating protein complexes push protons from the matrix out to the intermembrane space. This creates a concentration gradient of protons that another protein complex, called ATP synthase, uses to power synthesis of the energy carrier molecule ATP (Figure 2).
What is the final product of the electron transport chain?
The end products of the electron transport chain are water and ATP. A number of intermediate compounds of the citric acid cycle can be diverted into the anabolism of other biochemical molecules, such as nonessential amino acids, sugars, and lipids.
How do NADH and FADH2 power ATP formation quizlet?
How do NADH and FADH2 power ATP formation? by rearranging and oxidizing citrate though several intermediate molecules. the energy and electrons derived from these chemical reactins are stored in ATP, NADH, and FADH2. A molecule of CO2 is released in two of these chemical reactions.
What is the main advantage of fermentation over aerobic cellular respiration quizlet?
What is the main advantage of fermentation over aerobic cellular respiration? Fermentation generates ATP even if O2 is not present.
What is the electron transport chain in simple terms?
The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.
