the activation energy. Enzymes are used to reach the correct activation energy in plants. They lower the activation energy to the correct amount for the reaction to take place. Certain enzymes catalyze certain reactions, which means that many enzymes to operate the cell. On each cell, there is a spot where the substrate will attach to the enzyme (active site). When the substrate and the enzyme come in contact with each other, it creates an enzyme-substrate complex. The enzyme and substrate then connect

Alcohols effects on Liver Fatty Liver * Fatty liver is reversible, and is present in a high % of heavy drinkers. * Caused by fat droplets from adipose tissue, can lead to higher BP, hypertension - stroke Hepatitis * Reversible with complete absence of alcohol in the system for a long period of time, but 75-85% turns chronic. * Causes inflammation/necrosis of the liver tissue * Centre for disease control (CDC) 2007 stated hepatitis kills more patients than HIV/Aids. * 15

(SSF) is presented. The most important lignocellulolytic fungi and their properties are described, and their application in novel solid state bioreactors with on-line process control is discussed. The most important bioconversion products, biofuels, enzymes, animal feeds, biofertilizers, biopesticides, biopromoters, secondary metabolites, and the economy of their production by SSF is discussed. The use of SSF in the pulp and paper industry and in integrated crop management is illustrated. © 2002 Elsevier

Fatmata Diffusion Abstract dialysis tubing is, made of cellulose because it’s a selectively permeable membrane. In this experiment, we are testing to see if the solution in the beaker moves into the dialysis bag. Which because of that, Introduction Diffusion and osmosis are two types of transport mechanisms. Diffusion is the movement of molecules from areas of higher concentrations to areas of lower concentration until the molecules are evenly distributed through the area. Osmosis is the dispersion

Enzyme lab report Determining the properties of an Enzyme Introduction: Enzymes are proteins that acts as catalysts for reactions. This means that enzymes lower the activation energy essential for a reaction to take place, allowing a specific reaction to occur much quicker and easier. Certain enzymes only lower the activation energy for certain reactions, and enzymes are shape precise. The distinctive

sliding door. The teeths job is to grind up food. After that you walk into the mouth`s lobby. You walk over to the front desk to grab your saliva key. The saliva moistens the food making it easier to swallow. Saliva contains an enzyme known as salivary amylase. This enzyme chemically digests large starch molecules into smaller sugar molecules. The saliva makes the food wet so it turns into a blous. Then you walk on the tongues red carpet to the elevator. The tongue pushes the food to the back of the

Physiology 330 2/17/2016 Acclimation of metabolic enzymes in reptiles It is necessary for reptiles and all other animals to maintain a state of homeostasis within the body. I fluctuation of enzymes within the body must happen in order for such animals to maintain relative body temperatures needed for survival. Reptiles that undergo changes in body temperature over the seasons will demonstrate fluctuations in the activity of metabolic enzymes; specifically lactate dehydrogenase, citrate synthase

Introduction Enzymes are protein molecules that catalyze chemical reactions in all living organisms. Enzymes allow living organisms to carry out complex chemical activities at low temperatures, but can’t cause a reaction that hasn’t occurred in their absence. Also, enzymes are thought to speed up reactions by bringing reacting molecules together to increase the chances that a reaction will occur (Worthington Biomedical Corporation, 2015). Each enzyme has a specific active site where the substrates

Data: See attached sheet Discussion: The catalase enzyme does not work at high temperatures around or above 50 degrees celsius. We proved this in our lab when the slope changed from 0.021 kPa/sec at 34 degrees celsius to negative 0.009 kPa/sec at 54 degrees celsius. With just a change in 20 degrees the slope, or how well the enzyme is working went from really good to really bad. The catalase enzyme works best around a pH of 10. At a pH of 4 and 7 the slopes were 0.007 and 0.009 kPa/sec. At the
