Explanation:
Answer:
Mitochondrial inner membrane. (Ans. C)
Explanation:
Proteins of the electron transport chain present in the mitochondrial inner membrane. The electron transport chain at the inner mitochondrial membrane forms a proton gradient, which is driving the synthesis of ATP with the help of chemiosmosis.
Oxygen forms water by accepting electrons, and picking up protons, and it sits at the end of the ETC. In the absence of oxygen ETC will stop running, and chemiosmosis will no longer able to produce ATP. Cells are not able to carry out the reaction they need to function, and may die after a long period, in the absence of ATP.
I think the correct answer from the choices listed above is the last option. It is the hormone oxytocin that is controlled by a positive-feedback mechanism. Oxytocin is normally produced by the paraventricular nucleus of the hypothalamus and released by the posterior pituitary.<span> Hope this answers the question.</span>
Ciliated ependymal cells:<u> circulate cerebrospinal fluid.</u>
Ependymal cells are a type of epithelial cell that is associated with the cavities of the body through which the cerebrospinal fluid circulates.
- They are part of glial cells, which share space with neurons in the nervous system.
- They create the membranes that keep cerebrospinal fluid circulating through the ependymal canal of the spinal cord and the cerebral ventricles.
- For this, the ciliated structure that these cells present is essential for a correct movement of the cerebrospinal fluid, preventing it from spilling through other tissues and passing to areas of the body where it should not be.
- The cilia move rhythmically creating tiny currents for fluid to flow through the central nervous system.
- A small fraction of highly specialized and modified ependymal cells, called choroidal cells, are responsible for generating this essential fluid.
Therefore, we can conclude that ciliated ependymal cells circulate cerebrospinal fluid.
