Biochemistry Unit The Kinetics of Alkali Phosphatase Inhibition 1. OVERVIEW This practical builds on the enzymology lab skills you learned in the Acid Phosphatase practical. Again‚ you will measure the initial reaction velocity (V 0) of an enzyme reaction‚ but this time in the absence and then presence of an inhibitor. Last time you used Acid Phosphatase (Prac 1)‚ but this time you will use the enzyme Alkali Phosphatase. These enzymes have different primary (and hence tertiary) structures

events like super-storm Sandy continue to increase in their frequency and severity? Many modern scientists attribute these dangerous environmental trends of global warming to the ‘greenhouse effect’. The ‘greenhouse effect’ results from greenhouse gases such as carbon dioxide rising into the atmosphere‚ trapping infrared radiation from the sun‚ and emitting ultraviolet radiation that can puncture the earth’s stratospheric ozone layer. A healthy ozone layer should prevent this from happening‚ but the

Experiment 4: Behavior of Gases Introduction: In this experiment‚ the problem trying to be solved is what gas laws are being used when the pressure‚ temperature‚ and volume are being measured. The three gas laws are Boyle’s Law‚ Charle’s Law‚ and Gay-Lussac’s Law. The Boyle’s Law is when volume and pressure are being compared. Pressure and volume are inversely proportional‚ because when pressure goes up‚ volume goes down. The Charle’s Law is when volume and temperature are compared. Volume and

Experiment #1 Date: September 13‚ 2011 Title: Diffusion in Gases I Aim: To observe the diffusion of bromine Apparatus and Materials: Glass tube‚ bromine‚ fume chamber Diagram: Procedure: -Liquid bromine was placed in a jar and covered Observations: When first placed in the jar the original color of bromine was red-brown. As it began to diffuse its color changed from dark brown to a lighter brown until it becomes a yellow-like orange color. As it was diffusing liquid bromine changes its state

The transition metals are placed in the centre of the periodic table‚ between groups 2 and 3. They are generally hard and dense‚ and less reactive than the alkali metals. Iron‚ copper‚ silver and gold are important transition metals. The transition metals: overview The elements in the centre of the periodic table‚ between groups 2 and 3‚ are called the transition metals. Most of the commonly used metals are there‚ including iron‚ copper‚ silver and gold The transition metals Common properties

How to Remove Heavy Metal Toxins with Oral Chelation Do you currently have heavy metal toxins damaging the inside of your body? The answer is unfortunately "yes" for over 99% of us! So what is a “heavy metal” and what do I need to know? If you’re thinking of Ozzy Osbourne‚ KISS‚ or Ted Nugent‚ you’re not alone. The truth is that most people do not fully understand the real dangers of heavy metal poisons and just how common they are in our modern world. Fortunately‚ you can take steps to understand

Lockyer. Helium has an atomic number of 2 and an atomic weight of 4.002602. Helium is represented by the symbol of He. Helium is the second lightest element after Hydrogen and considered as the least reactive element. The more an element is reactive‚ the more flammable it is. It is considered a non-metal element with a number of 2 stable isotopes. It is a gas at room temperature with a density of 0.0001785 per cubic centimeter. Helium is an odorless‚ colorless‚ tasteless and nontoxic element. Natural

The purpose of this experiment is to discover the physical and chemical properties of the studied gases. In discovering these properties it allows the student or observer the ability to identify these gases when they come into contact with them. Procedure Before I began the procedure I gathered all my supplies from the given list in the manual. From there I began the actual experiment and diluted the HCL placed in a test tube and then placed the ZN in the tube as well. I placed the stopper

Greenhouse gases Carbon dioxide is a colourless‚ odourless gas that makes up .04 percent of the earth’s atmosphere. It’s released by the breakdown of organic materials‚ by animals when they respire‚ and by the burning of fossil fuels. Carbon dioxide isn’t toxic—after all‚ we exhale it with every breath and use it to make our drinks fizzy. However‚ carbon dioxide is considered a pollutant because‚ as a greenhouse (heat-trapping) gas‚ it’s a significant contributor to global warming. In the last 150
