The electrons that are passed to NADPH during noncyclic photophosphorylation were obtained from?
The electrons that are passed to NADPH during noncyclic photophosphorylation were obtained from water. The ultimate electron and hydrogen acceptor in the noncyclic pathway is NADPH+.
In the noncyclic pathway?
In the noncyclic pathway of photosynthesis, electrons from water are used to generate NADPH and ATP to drive the Calvin cycle. This pathway involves both Photosystem I and II working together to produce energy-rich molecules for carbon fixation. It is essential for the production of organic compounds in plants.
When does a redox reaction produce electricityOnly when an electrical device is attached Whenever electrons are transferred between atoms When electrons are transfered and a pathway for electrons is providedWhenever a pathway for electrons is provided?
A redox reaction contain oxidation and reduction half reaction you can prove it by using oxidation numbers
When tracing the flow of electrons in the mitochondria which represents the correct pathway?
Electrons flow through the electron transport chain (ETC) in the inner mitochondrial membrane. The pathway starts with NADH and FADH2 passing their electrons to complex I and complex II, respectively. The electrons then flow through the complexes, generating a proton gradient that drives ATP synthesis.
What are the differences between cyclic and noncyclic electron flow?
in non-cyclic the electrons do not return the source and the cyclic the electrons come back to the source. Mostly the non-cyclic process occurs to produce ATP AND NADH which will be used by the Calvin cycle to produce the carbohydrate but some times there occurs a cyclic process to produce ATP to cope up with Calvin cycle as it requires more ATP than the NADH In addition to the above, cyclic electron flow could operate independent of photosystem II. The production of oxygen and NADPH take place in non-cyclic electron flow and the system could switch to cyclic flow upon accumulation of oxygen and NADPH
When an organic product such as pyruvic acid is the final electron acceptor in the metabolic pathway the pathway is termed?
The pathway is termed fermentation. In fermentation, organic products like pyruvic acid accept electrons in order to regenerate NAD+ from NADH, allowing glycolysis to continue in the absence of oxygen.
Inside an active mitochondrion most electrons follow which pathway?
citric acid cycle- nadhelectron transport chain- oxygen
What is ED pathway?
The Entner-Doudoroff (ED) pathway is an alternative pathway to glycolysis that bacteria can use to break down glucose and produce energy. It involves a series of chemical reactions that ultimately result in the production of pyruvate and other precursor molecules for biosynthesis. The ED pathway is less common than glycolysis but is more efficient in terms of ATP production per glucose molecule.
What is a pathway that electricity travels through called?
A pathway that electricity travels through is called a circuit. It consists of a closed loop that allows for the flow of electrons from a power source through wires and components, back to the power source.
What are two key substances that must be present for conduction?
Two key substances needed for conduction are electrons and a conductive material. Electrons serve as the charge carriers that move through the material, while the conductive material provides a pathway for the electrons to flow.
What is the pathway between the receptor and the control center in the reflex pathway called?
Afferent pathway
What is the explanation for the pathway of electron transport chain?
The electron transport chain is a series of protein complexes and molecules embedded in the inner mitochondrial membrane. It facilitates the transfer of electrons from NADH and FADH2 to oxygen, generating ATP through oxidative phosphorylation. This process creates a proton gradient that is used to drive ATP synthesis.
