Collagen Collagen functions as a structural component. Collagen is the most abundant protein in the human body and is the substance that holds the whole body together. It is found in the bones, muscles, skin and tendons, where it forms a scaffold to provide strength and structure. Lupus is a collagen vascular disease that causes unique symptoms in each patient. Additional symptoms can include shortness of breath, chest pain, headaches, and dry eyes. People with lupus may have long periods of…

To begin, the role of the ACH receptor is vital to biology. An incoming action potential to an alpha motor neuron causes acetylcholine or ACH, at the end plate. The ACH binds to ACH receptors on the sarcolemma causing a depolarization through sodium influx. In your body, calcium performs a number of basic functions. The body uses around 99 percent of its calcium to keep bones and teeth strong, as a result, supports skeletal structure and function. The rest of the calcium in your body plays…

mammals of the egg. This contact triggers the acrosome to release the hydrolytic enzymes that were housed within. The acrosomal enzymes job is to penetrate and put a hole into the jelly layer. Why the enzymes are breaking down the jelly layer the actin within the sperm is growing and forming a structure that protrudes from the sperm head with proteins called bindin leading the way this structure is called the acrosomal process. The bindin from the sperm interacts with the bindin…

muscle is the 427kDa isoform. Dystrophin is made up of four domains: an N-terminal, a rod domain composed of 24 triple helix repeats and 4 hinges, a cysteine-rich domain and a C-terminal. The N-terminal of the protein binds to actin filaments and acts as a bridge between the actin cytoskeleton and the extracellular matrix via interactions with the dystroglycan complex (DGC) in the sarcolemma in muscles (5). Dystrophin helps to increase membrane stability and prevent the sarcolemma from…

respiratory or cardiac difficulties. Duchenne muscular dystrophy is the most common sex-linked disease. Dystrophy happens when mutation occurs on the gene that makes dystrophin. Dystrophin is protein that protects muscle tissues and it links cytoskeletal actin in muscle fibers with the surrounding…

Structure of Tight Junctions and their Dynamic Functions in Health and Disease Tight junction (TJ) discovery in the 1960s helped determine the nature of paracellular transport while the discovery of their constituting proteins subsequently improved understanding of TJs’ dynamic structure. Their role can be appreciated particularly in epithelial cells and when their formation is compromised; I aim to briefly explore the cause of Crohn’s disease to illustrate this. Furthermore, I will outline the…

Determining phylogenetic relationships of marine invertebrate and vertebrate using variation in muscle proteins of different genera; Ostreidae , Teuthida, Pectinidae, Nephropidae, Caridea, Brachyura and Oncorhynchus. Introduction The fundamental core of all biology emanates from evolution, as the great evolutionary biologist Theodosius Dobzhansky once said "Nothing in biology makes sense except in the light of evolution"(1973). Therefore, studying the phylogenetic relationships of different…

Brazilian Jiu-jitsu Brazilian Jiu-jitsu, or BJJ, is a style of martial arts, modified from the ancient Japanese art of Jiu-jitsu by the Gracie family and others, based on using an opponent’s momentum and leverage against them for defense. It involves take-downs and grappling, and has become a large sport that can be seen incorporated in the televised sport Mixed Martial Arts, or MMA. BJJ is a high intensity sport that involves endurance training as well as resistance training and explosive…

ASSOCIATION BETWEEN AMYLASE ENZYME AND AMY1A GENE COPIES Muntaha Ahmed – 400145234 Biology 1A03 Lab Section: L16 Lab TA: Samantha Li November 22, 2017 ABSTRACT This research experiment was conducted for the purpose of attempting to find a relation between the amylase (AMY1A) gene copy numbers and the production of the amylase enzyme (mg/mL) (Tracey 2017). The results for this experiment were obtained in laboratory experiments we conducted, through which we had found the number of…

“In No Turning Back” Estelle Freedman mostly gives international examples of the threat or action of rape to terrorize women. Despite a lack of examples from America in her article, the threat and actin of rape to control a woman’s behavior is existent on a daily basis in this country. One example that comes to mind is in marriage. For example, if a man and a woman are married, and the woman is a stay at home man, who depends on her husband as the only source of income, the threat of rape might…
