What is the final electron acceptor in glycolysis?
The final electron acceptor in glycolysis is oxygen.
What is the final acceptor in electron transport chain?
Oxygen
Oxygen is the terminal electron acceptor in the mitochondrial electron transport chain and therefore is required for the generation of energy through oxidative phosphorylation.
What is the final electron acceptor during respiration?
Oxygen is the final electron acceptor in this respiratory cascade, and its reduction to water is used as a vehicle by which to clear the mitochondrial chain of low-energy, spent electrons. The enzyme that catalyzes this process, cytochrome oxidase, spans the mitochondrial membrane.
What is a final electron acceptor in biology?
In biology, a terminal electron acceptor refers to either the last compound to receive an electron in an electron transport chain, such as oxygen during cellular respiration, or the last cofactor to receive an electron within the electron transfer domain of a reaction center during photosynthesis.
What is the final electron acceptor in photosynthesis?
NADP
The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product. In anoxygenic photosynthesis various electron donors are used.
What is the final electron acceptor quizlet?
At the end of the chain, the electrons join with protons and oxygen in the matrix fluid to form water. Thus oxygen is the final electron acceptor.
What are the electron acceptors in photosynthesis?
The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product. Cyclic phosphorylation is important to create ATP and maintain NADPH in the right proportion for the light-independent reactions.
What is the final electron acceptor in photosynthesis quizlet?
What is the final electron acceptor in the light reactions of photosynthesis? the final electron acceptor is NADP+ and not oxygen.
What is the final electron acceptor in the Calvin cycle?
NADPH is the reduced form of the electron acceptor NADP+. At the end of the light reactions, the energy from sunlight is transferred to NADP+, producing NADPH. This energy in NADPH is then used in the Calvin cycle.
What is the final electron acceptor in the electron transport chain resulting in the creation of water?
At the end of the electron transport system, two protons, two electrons, and half of an oxygen molecule combine to form water. Since oxygen is the final electron acceptor, the process is called aerobic respiration.
Which of the following final electron acceptors is used during anaerobic respiration?
Anaerobic respiration is the formation of ATP without oxygen. This method still incorporates the respiratory electron transport chain, but without using oxygen as the terminal electron acceptor. Instead, molecules such as sulfate (SO42-), nitrate (NO3–), or sulfur (S) are used as electron acceptors.
What is final acceptor in Krebs cycle?
Many aerobically respiring bacteria, including E. coli, switch to using nitrate as a final electron acceptor and producing nitrite when oxygen levels have been depleted. Microbes using anaerobic respiration commonly have an intact Krebs cycle, so these organisms can access the energy of the NADH and FADH 2 molecules formed. However, anaerobic respirers use altered ETS carriers encoded by their genomes, including distinct complexes for electron transfer to their final electron acceptors.
Is FADH2 an electron acceptor?
NADH and FADH2 that act as electron carriers give away their electrons to the electron transport chain. The electron transport chain refers to a group of chemical reactions in which electrons from high energy molecules like NADH and FADH2 are shifted to low energy molecules (energy acceptors) such as oxygen .
What is the ultimate electron acceptor in photosynthesis?
The electron acceptor in photosynthesis is NAD+ while in respiration the electron acceptor is NADH. In cellular respiration reaction 36 molecules of ATP are produced in complete oxidation of one molecule of glucose.
What is energy acceptor?
energy acceptor. a molecule (e.g. CYTOCHROME) capable of receiving energy (usually in the form of electrons) and of passing it on to another acceptor, as in an ELECTRON TRANSPORT SYSTEM.
