Essay about The Functions of Proteins

Enzymes break down molecules in our body faster than they would normally break down without enzymes.

Proteins are important for the human body. Proteins play many important roles in the body including the structure of enzymes; these are important proteins that help reactions occur in the body, such as releasing from the food we eat. Proteins also function as transport proteins such as hemoglobin; an iron

The human body is an incredible system that is capable of working a multitude of diverse functions. Without the help of the many different protein molecules, the human body would not be able to function properly. One major group of proteins called enzymes are mandatory for essential life. These proteins are constantly at work assembling molecules, metabolizing energy, and fighting off infections. An enzyme is a macromolecule that acts as a catalyst that speeds up a chemical reaction without being consumed by the reaction. Without these proteins, these reactions would take place too slowly to keep us alive. Essential parts in your body like vitamins and minerals cannot do any work without

Enzymes are biological catalysts, which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats, carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes, most physiological processes would not take place. Hundreds of different types of enzymes are present in plant and animal cells and each is very specific in its function.

Proteins are essential for cellular functions in all forms of life. Though proteins have been studied for decades, membrane proteins have not been properly understood due in part to their physical complexity and the difficulties in testing. Though many challenges hinder the discoveries in this area of biochemistry, Professor Alessandro Senes believes that the difficulties encountered only make the results more worthwhile. Researching these proteins advances our understanding of the importance of the protein structure on the molecular function in the cells. As Professor Senes and his team continue to explore recurring patterns in these membrane proteins, they further explore new topics in this growing area of science.

Proteins are one of the key biomolecules that make up the human body and facilitate different processes and reactions in the body (Silverthorn, 2016). Proteins exist in every cell in the human body and there are many different types of proteins with specialized functions that are necessary to maintain homeostasis (Silverthorn, 2016). Enzymes are a type of protein that performs like catalysts in the cells and start specific reactions (Ira, 2009).Catalysts start or increase the rate at

Proteins are important as they help build muscles and help the body repair itself. Without protein we would probably be very weak. One way proteins help our body helps our bodies is that enzymes act as catalyst for chemical reactions in our bodies. This helps the body perform more efficiently. Antibodies are also proteins. These proteins help the body defend against infection. Proteins also act transport. They help bind atoms and molecules and transmit them throughout cells and the body. Proteins provide many uses to our body and are therefore important. We need

In all living things, there are chemical reactions that happen within these living organisms to help them either break up energy or use the molecules for other bodily functions. One of the main chemical reactions are caused by something called Enzymes. Enzymes are basically catalyst that are organic which are made up of hundreds of amino acids and are pertained as fairly large (Biology Department, n.d, p.34). Similar to other catalyst, enzymes have the capability of fulfilling their function without allowing themselves to be consumed as well as disfigured. Enzymes can also carry on their function without changing the chemical equilibrium between reactants and products (Cooper GM, 2000). Enzymes main function is to help quicken the chemical reaction rate. These enzymes work in a way where there is a little area that is comparable to a depression. This depression area is known as the active site which is where the enzymes bond to. “The binding of a substrate to the active site is a very specific interaction” (Cooper GM, 2000). On top of the acceleration of chemical reactions, the enzyme has two other parts as well. The second function of enzymes is that they have specific reactants that they work with and these are called the substrates. These substrates help produce products for living organisms. Lastly, enzymes work in a way where if one was missing, the end product could be catastrophic. “Enzymes are regulated from a state of low activity to a state of high activity and

DVL 1 protein is a cytoplasmic phosphoprotein produced by DVL 1 gene regulating the cell formations and a transducer particle for the developmental processes such as neuroblast specification and segmentation.1 In Wnt Signalling Pathway, the DVL 1 protein works by binding to C-terminus of frizzled receptors and transduce the wnt signal in both canonical and non-canonical pathway.2 These pathways activation lead to the accumulation of beta catenin protein in the cell which known to have important roles in proliferation and formation of the cells.2

Enzymes speed up metabolic reactions necessary for life. Without them certain vital processes would not take place and the body would be unable to function.

Carbohydrates give the body energy. As the body's main source of fuel, carbohydrates are needed for physical activity and organ function. All the cells in the body need carbohydrates to function. Carbohydrates are also important for intestinal health and waste elimination. Proteins are extremely important in our cells. Proteins are involved in almost all cell function. Every protein in the body is designed for a specific task. Proteins are used in structural support, bodily movement, and in defense against germs. Proteins vary in structure and in function. They are constructed from a set of twenty different amino acids and each protein has a distinct three-dimensional shapes.

Enzymes are important to the human body because without it the reactions that do take place in the body would be to slow to keep a person alive. Some examples of enzymes are: pepsin, amylase, and lipase. Pepsin enzymes are found in the stomach they digest proteins. Amylase enzymes are found in the mouth it helps break down starch. Lipase enzymes break down fats. Also, Lipase enzymes help convert fat into energy.

Not only does hemoglobin has four heme groups, but it also has four polypeptides (two beta globin protein and two alpha globin). The two beta globin protein chains combines with two alpha globin protein chains and a heme which forms the predominant hemoglobin that is found in human adults.

Protein is also the largest dry weight in the body . The primary functions of proteins are to repair worn out, wasted,or damaged tissue and build new tissue in its place. Protein meets the growth needs and maintains tissue health during our adult years. Protein also helps repair skin and the tissue and maintains a fluid and electrolyte balance, this helps with swelling (edema) , and also develops antibodies. Protein is also used to build special white blood cells, these blood cells are called lymphocytes . They also produce antibodies as part of the bodies immune system to help defend against diseases and infections. Proteins are important to our bodies because they help with our hormones, enzymes, metabolism, digestion, and help to provide energy . Protein can be found in animal and plant sources. These sources are put into two groups, complete and incomplete

Proteins : are organic nutrients that are chemically similar to fats ( lipids ) and carbohydrate since they contain carbon , hydrogen and oxygen atoms . Also proteins contain nitrogen , actually nitrogen is the cells that need to make a big group of important biological compounds. Animals , plants , bacteria and viruses contain large amount of proteins . Any cells in human body contain proteins . There are a lot of proteins in human body have a different function . So the body use proteins to : first , body use proteins to make, maintain and repair cells such as cells during period of growth they need protein to form cells membranes .second , to build structures such as keratin which is a structural protein it’s in hair,
