Case Study: Chapter 3, Joseph’s Story A-H

A.) List Joseph’s risk factors and create a brief summary of the information you have so far. Identify how his risk factors would affect cellular function.

* The risk factors that Joseph had were smoking, lack of exercise, excessive weight gain, stressing, fatty foods, and a family history of vascular disease. Joseph is middle age Caucasian male who has suffered a heart attack. This may have been caused by him not taking care of his body properly. Joseph is already at high risk for heart disease due to a family history if vascular disease. He has also been stressing, an increase in weight, not exercising, and unhealthy eating. These things could all play a role in how his heart is affected and functioning. His cellular functions are being affected because there is no oxygen flowing throughout the body getting to the heart, cells, organelles, or membranes that keep the body functioning properly.

B.) Assuming Joseph’ heart has stopped, what cellular process and membrane functions are going to be affected by the loss of oxygen, blood glucose, and waste removal? * If Joseph’s heart stopped, the cellular process and membrane functions that would be affected are the aerobic process and the mitochondria. Oxygen and glucose are used in glycolysis which is reacted in the mitochondria where ATP is produced. Carbon dioxide is the waste product in this process and needs to be released. With oxygen and glucose not being present ATP cannot be produced and carbon dioxide cannot be released out the body. Therefor the cells are beginning to rapidly die and the pumps are begging to shut down. Without the main energy source for all cells the body cannot function properly.

C.) Which intracellular organelles have membranes as part of their structures? How would the breakdown of the membranes of these structures affect the function of Joseph’s heart cells? * The...
