Golgi Nobody

GOLGI BODY

The Golgi Body is a packing organelle quite like the endoplasmic reticulum. The Golgi bodies gather simple molecules and combines them to make complex molecules within the cell. This organelle produces Lysosomes which are essential for a cell's survival. In plants they create complex sugars and pass them around the cell in vesicles. It is structured as multiple layers of membranes clumped together and like the Rough ER they have ribosomes on their membranes. The Golgi Body works with the Rough ER through absorbing the its Transition Vesicle and making it a Secretory Vesicle and releasing it out of the cell.


A disease linked to the Golgi Body is Achondrogenesis which is a serious disease with the malformation of bones and cartilage. The babies with it are usually born prematurely with short limbs, a short body and other skeletal abnormalities. They are typically stillborn or they will die shortly after birth, occasionally they can live for a little bit with extensive care but still cannot live much longer. It is caused by a defect in the microtubules in the Golgi Body. In some cases the endoplasmic reticulum cannot move a protein to the Golgi Body so it now became irrelevant and the formation of bones and cartilage was not able to happen. Alzheimer's is also a disease caused by a malfunction Golgi Body. In the brain cells for Alzheimer's carriers their Golgi Bodies have failed which is an important step for the biochemicals of the brain for the aging process. Alzheimer's is characterized as dementia when a person starts off with short term memory loss, then onto some behavioral issues and they become recluse to society. They tend to only live about 3-9 years after the diagnosis of the disease. It is a severe disease. Thanks a lot Golgi Body.

Due to a block in the ER-Golgi transport and an accumulation of the protein synuclein it leads to Parkinson's Disease. Dopamine cells in the midbrain die which causes it. The disease starts off with shaking, slow movement and difficult walking but it leads to dementia and thinking and behavioral problems. Depression and emotional issues are very common symptoms with the disease. The disease is much more common with people over 50.Voice issues, tremors, and festination are big issues with the disease as time goes on. Another disease is Smit-McCort Dysplasia caused by mutations in RAB33B which leads to Golgi swelling and fragmentation. It is characterized by short limbs and trunk with barrel shaped chest. The person suffering from the disease also has platyspondyly, abnormalities in epiphyses and metaphases and a compressed spinal cord.

Parkinson's Disease
Does the Golgi Body really seem capable of being the Organelle in Charge? I think not. It causes too many severe issues for people including death. Plus it relies so much on the endoplasmic reticulum to help function which when that passage way gets blocked many issues arise. Let's put a more reliable organelle in charge and have him lead this country as a true leader. VOTE CHLOROPLAST.
