The Vesicles Transport Hormones, Enzymes, and Chemicals Essay

Chemical Kinetics is the branch of chemistry that studies the speed at which a chemical reaction occur and the factor that influence this speed. What is meant by the speed of a reaction is the rate at which the concentrations of reactants and products change within a time period. Some reactions occur almost instantaneously, while others take days or years. Chemical kinetics understanding I used in the process of designing drugs, controlling pollution and the processing of food. Most of the time chemical…

The mitochondrion is an organelle which originated from the endosymbiosis of eubacteria and, as a result, contains its own genome which encodes for essential mitochondrial transcriptional machinery proteins and subunits of electron transport chain (ETC) complexes [1, 2]. However, the vast majority of mitochondrial proteins are encoded for by the nucleus [3]. As a result, these two organelles must be able to communicate in order to coordinate protein synthesis and maintain mitochondrial homeostasis…

be observing a chemical reaction dealing with enzymes. You may ask, what are enzymes? Enzymes are proteins produced by living cells. For example, you have enzymes in your digestive system to help you break down food. Without enzymes, organisms will not be able to survive. Enzymes act as catalyst in biochemical reactions and catalyst speeds up the reaction by lowering the amount of activation energy. Activation energy is required for reactants to react into products. Although enzymes are essential…

work that they did on transport vesicles within the cellular membrane. The recipients discovered how the cellular transport system was organized so that transport material was delivered to the correct site with proper timing. Rothman discovered how the vesicle is able to fuse with a cell membrane or organelle to deliver its contents. Schekman through the study of yeast isolated the genes required to code for vesicle transport. Südhof found the signals that tell vesicles when to release their contents…

Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others, where they are effective in very small amounts. Depending on the target tissue, a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized…

break down and formation of chemical substances in the body that is needed for energy, for formation and breakdown of tissues and cells, and to maintain homeostasis of the body. Concept Key Terms: • Adrenal: endocrine glands that are located on top of the kidneys and are responsible for several hormones like aldosterone, corticosteroids, • Aldosterone: hormone secreted from the adrenal gland to signal the kidneys to retain sodium from the excretion • Autocrine: a hormone that is released and acts…

biological concepts to find out the different chemical reactions that take place in the bodies of living organisms and the influence of various organic substances in these reactions. The reactions are influenced by various enzymatic actions that are very important in the body as they help in activities such as the breakdown of substances for assimilation in the body. This paper explains the various processes taking place in the body and the effect of enzymes on chemical reactions in the body. Background information…

Transport Across Plasma Membrane The plasma membrane covers all living cells, enabling the cells’ contents to be held together and controls movement of substances into and out of the cell. Plasma membranes are made of phospholipids, proteins and carbohydrates. The phospholipids are essentially made out of two fatty acid chains and a phosphate-glycerol group. They are arranged in a bilayer with the hydrophilic phosphate head facing outwards and the hydrophobic…

Enzyme Simulation Lab Problem: How does enzyme concentrations affect the rate of a chemical reaction? Introduction: The experiment consists of enzymes speeding up a chemical reaction. An enzyme can speed up a chemical reaction because the function of an enzyme is that it acts like a catalyst which helps speed up a chemical reaction. The experiment consist of an enzyme because the enzyme would be the person trying to break the toothpicks and the substrate would be the toothpicks since the enzyme…
