Case Studies

Case Study A Explanation

Benjamin is missing Lysosomes. Lysosomes have enzymes that break down lipids and polysaccharides. When there are not lysosomes to break down lipids and polysaccharides, they build up in the body and can cause joint and bone pain. The lysosome is pretty much the only organelle that breaks down lipids and polysaccharides and that is also .5-1.5 microns in size.

Case Study B Explanation

Olivia is missing the mitochondria. The mitochondria takes glucose and oxygen in and gives out ATP(and some other things like water and carbon dioxide), which is energy. If there is not ATP present, that explains why Olivia is feeling weak. Not having the mitochondria to break down glucose would cause the glucose levels in the blood to rise. The mitochondria is the main organelle that is involved in cellular respiration.

Case Study C Explanation

Frank is missing Golgi Bodies. Golgi Bodies make vesicles of enzymes and sugars for the cell to use later or as they are made, which explains why Frank doesn't have the enzymes he needs for intestinal cells and digestion. The Golgi bodies also make lysosomes, and since lysosomes have enzymes for digesting, that could be why he is having problems with indigestion. Golgi bodies are the main organelle Frank is missing because Golgi bodies are 2500 nanometers in width and lysosomes are not.

Case Study D Explanation

Mary is missing peroxisomes. Peroxisomes have enzymes that break down uric acid, fatty acids and amino acids. Since there are no peroxisomes, that explains why those acids are building up in her blood stream, because there is nothing to break them down. Peroxisomes also help with the nervous system, which is why Mary is having back(spine) pain. Peroxisomes help make myelin, which Mary is lacking, and they are around .5 microns in length. It couldn't be another organelle because peroxisomes are the only one that is around .5 microns in diameter, help with the nervous/spinal system, break down fatty acids and uric acids, and help produce myelin.

Is There Any Organelle More Important Than The Rest?

All organelles in cells are important to the cell's function. Every organelle contributes to the survival of the cell in some way, or works with and helps another organelle in the cell. When one organelle is missing, it can cause problems. There is not one organelle more important than the rest because they all chip in a part to the cell's survival.
