(Evert‚ RF & Eichhorn‚ SE 2013). Enzymes also control plant metabolic processes such as respiration (Evert RF‚ Eichhorn SE & Perry JB 2013). This experiment focuses on the enzyme catalase. Catalase breaks down hydrogen peroxide into water and oxygen. Hydrogen peroxide is a waste product of cell metabolism that

Enzyme assay lab report Health and safety: 4-nitrophenol is harmful. Introduction: Enzymes are quaternary structured proteins that are specific biological catalysts that speed up a reaction without being used up. They contain an active site that allows substrate to bind to a specific area on the enzyme which is of a complimentary shape of the substrate. There are two models of enzyme action‚ the Lock and Key model and the Induced Fit model. The Lock and Key model states that the enzyme has a specific

The purpose of this lab was to determine how an excess amount of liquid‚ which was water‚ Gatorade and wine in this case‚ along with an excess amount of solute‚ which was the 7g NaCl pill‚ would affect the kidneys and the osmolarity of urine. Measurements of urine volume‚ specific gravity and chloride concentrations were recorded in order to investigate this. Our hypothesis stated that the volume of urine would increase for all groups other than the group drinking 80 ml of water along with taking

confirmed there was liquid flowing water on Mars on the 28th of September. The water was found running down slopes in the warmer months when the temperatures were above -10℉. The water was similar to our ocean water in the way that it was salty but the salt found in the water was more like what we use to de ice the roads. There are long‚ dark streaks that show where the water flows because as of right now there are no streams‚ rivers‚ or lakes on Mars so the water comes from under the soil and wets
