Answers to “Joseph’s Story”

Question B. When the heart is not pumping the oxygen and blood glucose can’t reach the major organs that need the heart to work for them to be sustainable, the cells would not be able to produce ATP after it uses all the energy left in the cell from rapidly burning it up when the oxygen level drops and this function gives power to the cell. The cells will stop functioning and eventually die because of the loss of power in the cellular life and the ATP shuts down the plasma membrane. The cells will began to leak, and sodium will start to leak into the call and potassium will leak out.

Question C. All intracellular organelles have membranes as a part of their structure. The breakdown of the membranes of these structures affect the function of the heart because the special calcium ATP had stopped moving calcium from the cytosol into the endoplasmic reticulum of his cardiac muscle cells. As the intracellular calcium levels rose, they caused proteases to spill into the interior of the cell, attacking the cytoskeleton. Lysosome enzymes normally bound safely inside vesicles begin to digest the plasma membranes of the organelles.

Question D. His predisposition for vascular disease is held in the Mitochondrial DNA. The information that is needed to repair itself is held in the DNA also but is mainly held in the Messenger RNA.

Question E. The integral membrane proteins, which are attached to lipids in the bilayer, the transmembrane proteins,and the polypeptide chain actually traverses the lipid bilayer. When these proteins start to build up and the ATP is not burning energy the homeostatic of the body becomes imbalance.

Question F. Reestablishing the oxygen flow to the body during the CPR helped the cells that did not die to release the carbon dioxide, help
