Which of the Following Best Describes the Electron Transport Chain

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. This flow of electrons allows the electron transport chain to pump protons to one side of the mitochondrial membrane.

Electron Transport Chain An Overview Sciencedirect Topics

The main role of the electron transport chain in cellular respiration is that it produces ATP molecules.

. C Electrons are pumped across a membrane by active transport. Complex IV consists of an oxygen molecule held between the cytochrome and copper ions. D Glucose is broken down to a three-carbon.

The energy from electrons is used to make ATP pyruvate is broken down into 6CO2 2ATP 8NADH and 2 FADH2 glucose and oxygen are used to make energy ATP for the body to use and H2O and CO2 as waste oxygen is not present and fermentation must occur. Oxidative phosphorylation is a process involving a flow of electrons through the electron transport chain a series of proteins and electron carriers within the mitochondrial membrane. Which of the following best describes complex IV in the electron transport chain.

Electron Transport Chain Definition. The electrons flowing finally reach the oxygen producing water. The electron transport chain is the third step in cellular respiration.

Complex IV contains a molecule of flavin mononucleotide and iron-sulfur clusters. In the process protons are pumped from the mitochondrial matrix to the intermembrane space and oxygen is reduced to form water. 65 Electrons are pumped across a membrane by active transport.

When electrons are passed from one component to another until the end of the chain the electrons reduce molecular oxygen thus. As the protons build up they create a proton-motive. Electron Transport Chain Definition.

NADH release the hydrogen ions and electrons into the transport chain. Electrons are passed from one carrier to another releasing a little energy at each step Electrons are pumped across a membrane by active transport Glucose is broken down to a three-carbon compound in preparation for the citric acid cycle Hydrogen atoms are added to CO2 to make an energy-rich. The NADH and succinate generated in the citric acid cycle are oxidized which releases the energy of oxygen to power ATP synthase.

D Glucose is broken down to a three-carbon. The electron transport chain in the mitochondrion is the site of oxidative phosphorylation in eukaryotes. 27 Which one of the following best describes the electron transport chain.

Photosynthetic electron transport chain of the thylakoid membrane. Adenine tri phosphate ATP is a molecule of energy which is produced during oxidation reduction reaction. In this assessment you will be required to answer questions about what happens during this step and in cellular respiration.

The principal molecules involved in transporting electrons to the electron transport chain are composed of _____. C Electrons are pumped across a membrane by active transport. At the end of electron transport chain to accept electrons and form H 2 O.

ATP is used by the cell as the energy for metabolic processes for cellular functions. If humans did not breathe in. The electron transport chain is a collection of proteins found on the inner membrane of mitochondria.

Electrons gain energy as they move down the chain. Which of the following best describes the electron transport. It is the only phase in glucose metabolism that makes use of atmospheric oxygen.

AElectrons are passed from one carrier to another releasing a little energy at each step. Electrons pass from one carrier to another releasing a little energy at each step. B Hydrogen atoms are added to CO2 to make an energy-rich compound.

Water is the last electron acceptor. The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH 2 to molecular oxygen. A Electrons are passed from one carrier to another releasing a little energy at each B Hydrogen atoms are added to CO2 to make an energy-rich compound.

NADH and FADH2 donate their electrons to the chain. Which one of the following best describes the electron transport chain. Which phrase best describes the Electron Transport Chain ETC.

This energy is used in most of the chemical reaction that is occur inside the cell. Electron transport is defined as a series of redox reaction that is similar to the relay race. The electron transport chain Figure 1.

13 Through the mitochondrial electron transport chain and oxidative phosphorylation energy stored in reduced NADH can be cashed in for equivalents of ATP. A molecule is oxidized when it _____. The electron transport chain is the first step in cellular respiration E.

It is a part of aerobic respiration. The electron transport chain is a crucial step in oxidative phosphorylation in which electrons are transferred from electron carriers into the proteins of the electron transport chain which then deposit the electrons onto oxygen atoms and consequently transport protons across the mitochondrial membraneThis excess of protons. The electron transport chain is driven primarily by changes in H concentration.

The electrons transfer. An electron transport chain ETC is a. 27 Which one of the following best describes the electron transport chain.

Which one of the following best describes the electron transport chain. Explain why each NADH is only worth 25 ATP rather than 3 ATP. 4 pts The number of ATP molecules that can be synthesized is related to the number of protons that are driven across the inner mitochondrial membrane to.
