Carrier Protein Research Paper

There are some integral proteins embedded in the phospholipid bilayer. Carrier protein is one of the integral proteins. The carrier protein provides the passage for the ions or large, polar molecules to move across the cell membrane. Some of the ions or molecules need to make use of the carrier proteins with the help of concentration gradients. Nonetheless, some molecules which are important to human body sometimes need to go against the concentration gradient.
There are two types of ways for the ions or molecules to pass through the cell membrane using carrier proteins. They are active transport and facilitated diffusion.
In order to understand transporting which molecule is important to human, undering the transport process is important. …show more content…

Glucose transporter 1 (GLUT1) is a kind of carrier protein responsible for the passage of glucose across the plasma membrane through facilitated diffusion or active transport. If the extracellular concentration is greater than the intracellular one, the glucose have to be mediated by carrier proteins for diffusion owing to the polar nature. Otherwise, the glucose will be transported by active transport. Being an important source of energy for human body, glucose is to maintain cellular respiration, which helps the synthesis of ATP, an energy source for primary active transport, such as the Na-K-ATPase. The lack of carrier protein results in blockage of glucose. Physically, insufficient of glucose will lead to a level of low blood sugar, which is known as hypoglycemia. According to Taylor and Rachman (1987), the low blood sugar will result in a poor cognitive function. The low blood sugar level will result in loss of consciousness and a rapid heart rate. Metabolically, lacking in glucose is a hindrance for ATP synthesis as well as the primary and secondary transport. Lacking in ATP will be a barrier for Na-K-ATPase to function. The resting membrane potential of our cells cannot be regulated normally. Neurotransmitters will function abnormally and will send wrong signal to our central nerve systems. Our human body will faint in the

permitted through facilitated diffusion involving glucose transporters. Glucose transporters are specialised for different cell types, for muscle and fat cells, type 4 glucose transporters (GLUT4) are used, as muscle cells are vital to athlete performance in the rainbow rage, GLUT4 shall be examined in this example. Firstly, insulin binds to insulin receptors on the surface of the cell. This sends a signal to GLUT4 vesicles from inside the cell initiating their movement to the cell wall. GLUT4 vesicles fuse to the outer cell membrane, catalysing the movement of glucose into the cell, this is the major endocytic process within cells.

Another illness that is mentioned in the book is diabetes. As Dr. Moalem describes it, “In diabetics, the process through which insulin helps the body use glucose is broken, and the sugar in the blood builds up to dangerously high levels.” The body either fails to produce enough insulin, or the body tissues become resistant to insulin, leading to high levels of glucose in the blood. The elevated levels of glucose build up in certain organs and the high glucose concentration in these organs can lead to serious complications, such as blindness, heart disease, stroke, vascular disease, nerve damage, and kidney damage. Some of the symptoms include fatigue, thirst, hunger, blurry vision, and the frequent need to urinate.

The stomata are the most critical piece to this process, as this is where CO2 enters and can be stored, and where water and O2 exit. Cellular respiration also known as oxidative metabolism is important to convert biochemical energy from nutrients in the cells of living organisms to useful energy known as adenosine triphosphate (ATP). Without cellular respiration living organisms would not be able to sustain life. This process is done by cells exchanging gases within its surroundings to create adenosine triphosphate commonly known as ADT, which is used by the cells as a source of energy. This process is done through numerous reactions; an example is metabolic pathway.

Why do we need it? Medical term of sugar is glucose, which we get from food and our liver. To make it easier to understand, glucose it a fuel needed to produce an energythat helps body tissues to build up our muscles. There is number of risk factors of diabetes already known for society, such as: family history, genetics, age, geography.

Type two diabetes can cause many issues and problems for the person involved. For example, one can develop kidney disease due to the fact that high levels of blood sugar make the kidneys filter too much blood. Waste products start to build up in the blood and eventually the kidney starts to fail. Secondly, diabetes can also cause amputations and blindness to occur in severe matters. The cause of nerve damage and poor circulation makes the feet and lower legs at risk of amputation.

Our bodies take in the glucose and turn it into energy we can then use. When we let glucose in, we are raising our insulin and glucose levels. Insulin is the hormone in people’s bodies that grants glucose access into our bloodstreams. However, insulin keeps our blood levels from raising or lowering, and it stores the fat to use for energy later on. Unfortunately, people have no control over the insulin function, though they do have control over the types of food they eat that contain certain amounts of glucose.

Huntingtin is a protein that is used to transport molecules within a cell, regulate transcription, inhibition of programmed cell death, and embryonic development. Huntingtin has been observed in assisting the intracellular movement of vesicles which transport molecules throughout the cell. Huntingtin does this by interacting with components of microtubules which serve as a highway for vesicles to move through the cell. Huntingtin serves as a major transportation protein primarily for the brain-derived neurotrophic factor protein (BDNF), which is important for striatal cells to survive. Furthermore, studies have shown that huntingtin serves as an important transportation protein for iron.

According to Robin Konie’s article, sugar is the body’s preferred and most easily accessible fuel source. Although sugar is one way to get the energy that our bodies need to function, there are other ways to get the energy we need. There are many people who experience “sensations of clarity, easy weight loss, when turning to a no-sugar or low-carb diet” (Konie). These people’s bodies using adrenaline and cortisol for energy.

Mild cases of low blood sugar can cause you to feel nervous or anxious, while more severe cases can lead to feeling irritable or tired, notes the National Diabetes Information Clearinghouse. Along with mood swings, low blood sugar levels can cause sleepiness, confusion, weakness, sweating, hunger and other symptoms (Macht 2000). If the human nation could get a grasp on the overconsumption of comfort foods and eating based off of how they feel, the percentage of obesity in the United States alone would fall drastically. I believe that when your emotions are controlled

Glucose, which is a six-carbon sugar, is at that moment divided into two molecules of a three carbon sugar. The breaking down of glucose, takes place in the cell’s cytoplasm. Glucose and oxygen are produced from this breakage, and are supplied to cells by the bloodstream. Also produced by glycolysis are, 2 molecules of ATP, 2 high energy electron carrying molecules of NADH, and 2 molecules of pyruvic acid. Glycolysis happens with or without the presence of oxygen.
