Cycle

Cell cycle overview The role of the cell cycle is to allow a cell to increase its mass, acquire nutrients, duplicate DNA and divide into daughter cells. There are three stages within the cell cycle, interphase, mitotic (M) phase and cytokinesis. Interphase is further divided into Gap 1 (G1), Synthesis (S) and Gap 2 (G2) where the main agenda for the cell is to grow, and obtain nutrients in preparation for the next phase. The next stage is the M phase and includes four consecutive events,…

succinyl-CoA synthetase, succinate dehydrogenase, fumarase, malate dehydrogenase, and citrate synthase. The Cori Cycle has many parts to it ultimately leading to the breakdown of glucose and the diffusion of lactate with the liver. In the Cori cycle there is the conversion of glucose to lactate through anaerobic glycolysis in muscle cells, the diffusion of lactate from muscle cells into the bloodstream then being transported to the liver. To the conversion of lactate to glucose through…

The business cycle is the alternating periods of growth and decline. There is four stages of the business cycle: Recovery, Peak, Recession, and Trough. During the recovery period the economy is growing. This means that there will be more job openings and businesses will increase product. People are willing to spend more money because times are good for them at the moment and they are very optimistic about the future. During the peak period the economy is at its highest point. This means that…

this cycle. Water stores in lakes and the ocean, transpires into the air creating condensation, precipitation back onto the planet's surface creating runoff, running into the ground creating ground water, and eventually making its way back to lakes and the ocean. This terrestrial system is continuous supporting life on the planet. Then, explain how various pollutants enter different phases of the water cycle as a result of business practices. When pollutants enter the water cycle,…

31 - Describe the biochemistry of the Cori cycle and the glucose–alanine cycle. How are they regulated and under what physiological conditions are they activated? The Cori cycle and glucose-alanine cycle are two mechanisms that involve cycling of nutrients between the liver and muscle. Lactate and alanine are two glucogenic molecules that are each converted to pyruvate via a series of enzymatic reactions in the liver to ultimately be converted to glucose via gluconeogenesis and transported…

I am a water molecule there are four stages to my life also know as the Water Cycle, these include precipitation, evaporation, condensation and sometimes absorption. Most of these stages happen to me on a daily basis. I am a very important part of the living world, as most living things need me to survive. When I am in the Water Cycle I normally come down from the sky through precipitation and condensation. This involves being brought down through snow, rain, or hail. Once I precipitate from the…

Web Server and Security Development Life Cycle Most organizations use web applications through the use of the internet as part of their business process and functions to fulfill their objectives, business requirements and needs of their company. When implementing these applications, they have to make sure that security is a part of each step that they follow in the development lifecycle. If security is not implemented, then such software or applications, such as web server or web application,…

The citric acid cycle generates energy from the oxidation of various fuel molecules to acetyl coenzyme A (acetyl CoA). Acetyl CoA undergoes several redox, hydration and decarboxylation reactions to produce carbon dioxide (CO2), reduced nicotinamide adenine dinucleotide (NADH), reduced flavin adenine dinucleotide (FADH2), adenosine triphosphate (ATP) and hydrogen ions. The citric acid cycle links glycolysis which produces pyruvate from glucose and oxidative phosphorylation which generates ATP…

There are two main models for Life Cycle Inventory Analysis, and they are very different between them. The Attributional Life Cycle Inventory is based on a description of how environmentally relevant physical flows affects life cycle and its subsystems. On the other hand, Consequential Life Cycle Inventory is based on describing how changes in Life Cycle itself affect the environmentally relevant physical flows. The main objective of this paper is to amplify the consequential model beyond the…

Introduction The urbanization of a catchment is a drastic change in land use, and has major effects on the hydrological cycle during heavy rainfall events because of its impermeable surfaces (G. E. Hollis). By recording the discharge in a catchment the data can be used to create a hydrograph. It is often useful to analyse a hydrograph because it shows how quickly rainwater moves to the stream channel (Holden J. 2012.) The aim of this study is to compare an urban and rural catchment, and to find…
