Answer:
ATP synthesis by oxidative phosphorylation will stop.
Explanation:
Cyanide inhibits cytochrome oxidase that passes electrons to the molecule oxygen. Cytochrome oxidase also pumps two protons from the matrix to the intermembrane space during electron transfer. Inhibition of cytochrome oxidase would not allow the transfer of electrons to oxygen and the whole electron transport chain would be stopped. There would not be any generation of proton concentration gradient to drive the process of ATP synthesis. Hence, ATP synthesis by oxidative phosphorylation will be stopped after cyanide poisoning in aerobic cells.
Uracil (U) is not part of DNA but is part of RNA
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
