The cell could not make ATP.
Explanation:
Glycolysis may be defined as the process in which a glucose molecule is broken down into the two molecules of the pyruvate. Pyruvate is used to produce energy through various pathways that depends upon the availability of the oxygen. However when the glycolysis in blocked and the pyruvate is not formed, then the cells would not be able to use either the fermentation or aerobic respiration or the perform citric acid cycle. So the cell does not make any ATP.
Arteries are thick-walled and elastic blood vessels.They carry blood away from the heart.Their thick walls withstand the force of blood from the heart.The nature of its surface reduces friction generated by moving blood.
