Are the two types of electron carriers used in cellular respiration NAD and NADH? Best Answer: NOOOO, Shawty is wrong! NAD is the electron carrier used in cellular respiration while NADH is just the reduced for of it. The two types of electron carriers used in cellular respiration are FADH2 and NADH. Source(s):

The Electron Transport Chain: Products and Steps In this lesson, we learned how we took the products of glycolysis and the citric acid cycle and used them in the electron transport chain, the third stage of cellular respiration. Electron carriers are reduced during glycolysis and the citric acid cycle to NADH + H+ and FADH2.

- In aerobic respiration, these electrons are passed from one carrier molecule to another in a series of oxidation-reduction reactions, and ultimately to the final electron acceptor, oxygen (O2), that combines with hydrogen, resulting a water (H2O), a metabolic waste product.

Electron transport chain The final acceptor of electrons in the electron transport chain is molecular oxygen. Electron transport chains are used for extracting energy via redox reactions from sunlight in photosynthesis or, such as in the case of the oxidation of sugars, cellular respiration.n oxidative phosphorylation, electrons are transferred from a low-energy electron donor (e.g., NADH) to an acceptor (e.g., O 2) through an electron transport chain. In photophosphorylation, the energy of sunlight is used to create a high-energy electron donor and an electron acceptor.

MADMAN BIOLOGY The electron transport chain is a series of electron carriers in the membrane of the mitochondria in eukaryotic cells. Through a series of reactions, the high energy electrons are passed to oxygen. In the process, a gradient is formed, and ultimately ATP is produced by oxidative phosphorylation. The enzyme ATP synthase uses the energy produced by the electron transport chain for the phosphorylation of ADP to ATP.

Electron Carriers in Cellular Respiration What Are Electron Carriers? Cellular respiration can be divided into three main steps, glycolysis, the citric acid cycle, and oxidative phosphorylation. During the first two steps, molecules called electron carriers harvest electrons from glucose. Electron carriers exist in two forms: oxidized and reduced. When a carrier has less electrons, it's in the oxidized form and when it is carrying electrons, it's in the reduced form. The process of converting between the oxidized and reduced forms are called redox reactions and are the basis for moving electrons during cellular respiration.

Cellular Respiration the carrier molecules of the electron transport chain use the energy of the electrons they're transporting to pump hydrogen ions out of the mitochondrial matrix and into the space between the membranes; this creates a gradient of hydrogen ions (more in space, less in matrix).he process in which NADH and FADH2 hand down electrons to a chain of carrier molecules; electrons are passed along the chain until they're given to oxygen, which forms water.

Examples of Electron Carriers Electron carriers are important molecules in biological systems. They accept electrons and move them as part of the electron transport chain, transferring the electron, and the energy it represents, to power the cell. Electron carriers are vital parts of cellular respiration and photosynthesis.

An  Online Introduction to Advanced BiologyTerms  and Concepts The various ways to do this are collectively called cellular respiration. The most efficient respiration processes use the best electron acceptors to get the most energy out of their fuel-nitrates, or sulfates, or carbonates can be used, but electrons are not mobilized enough to pull a lot of energy from the fuel.

- Cellular respiration utilizes oxygen at the end of electron transport. The electrons to reduce the oxygen molecule into water molecule are provided by the intermediate products, and are transferred to oxygen through electron transport cycle. Oxygen is used by the respiratory metabolic reaction in the following way.he method of harvesting energy from the food by the cells is cellular respiration. Cellular respiration occurs in two ways. One way is aerobic respiration and anaerobic respiration. Aerobic cellular respiration is a process in which the chemical energy stored in glucose produces ATP or adenosine tri phosphate.

What is the final electron acceptor in cellular respiration? Aerobic or anaerobic? In aerobic respiration, the terminal electron acceptor is oxygen. Anaerobes have a lot of terminal electron acceptors, depending on the organism. Back when life first got started, iron was probably the most common, and some anerobes still use iron as the terminal electron acceptor.
