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.

This So Called "Smoove ER"

SmoothER

The Smooth ER acts as a storage organelle that is important in the formation and holding of lipids and steroids essential for the cell. Those cells that are used in releasing oils typically have more Smooth ER than most other cells in the body. A variation of sarcoplasmic reticulum is an organelle that stores ions that the body will need for future use. Smooth ER doesn't only create lipids and hormones but it plays a large part in detoxifying a number of organic chemicals to be more water soluble and easier on the body. A large amount are found in the liver for breaking down alcohol.
Some diseases caused by faulty Smooth ER organelles would be Cerebral Ischemia, Multiple Sclerosis, Huntington's and Alzheimer's. The improper folding of proteins tends to lead to these neurological diseases. Cerebral Ischemia is the insufficient flow of blood to the brain which due to the lack of oxygen it will lead to an ischemic stroke. It leads to issues with brain metabolism, reduction in metabolic rates, and energy crisis with the main symptoms being impaired vision, speaking and motor skills. Due to the loss of oxygen in the brain one can become unconscious and if that happens for large amounts of time they can have permanent brain damage. MS is an inflammatory disease that happens when the insulating covers of nerve cells in the brain and spinal cord are damaged. The issues clouding this disease vary from mental, physical and even psychiatric as there is no current cure for this tough disease. Their life expectancies are about 5-10 years shorter than that of people without the disease. The issues go from the brain all the way down to the bladder affecting many parts of the body on the way down. They can have a loss of sensitivity or changes in sensation, become weak, muscle spasms, bladder and bowel issues, fatigue and even depression or unstable mood are apparent with this disease.

Huntington's Disease is a neurodegenerative disease that affects muscle coordination and leads to mental decline and behavioral issues. The early symptoms are subtle muscle problems, such as little twitches and poor coordination. As the disease progresses the issues with muscle coordination gets much worse and the mental state of the person is getting worse. Physical abilities eventually get so bad that easy movements are too hard to perform while those mental abilities will deteriorate into dementia. Pneumonia, heart disease and falls shorten the life expectancy to about twenty more years after those symptoms become apparent. Some mental symptoms will start off with depression or anxiety, leading into a recluse behavior, egocentrism, aggression and even with addiction such as alcoholism or a drug problem. This disease has no cure and makes life very difficult for those affected by it. Alzheimer's is a neurodegenerative disease that affects many people in the country. It starts off with just having short term memory loss but gradually worsens. As it gets worse the person can become disorientated, have a problem with language, become very moody, unable to care for oneself and have behavior issues. They began to withdrawal from society the disease is so bad. Bodily functions become lost which then their death is eminent. The life expectancies after getting the disease is about 3-9 years. It is said to be one of the most financially costly diseases with their being no cure and having to have a constant watch over the person with it. In 2010 it was said that there was between 21-35 million people worldwide affected by this awful disease. Alzheimer's not only affects those with it but those people's families lose their loved one as they become recluse and eventually die.

The Smooth ER leads to too many neurological defects that we could not have him as the Organelle in Charge as he may not be stable enough to lead this large nation. A bad brain cannot lead this country. Vote Green, Vote Chloroplast!
