potential. 3. 4. 5. K+ is more permeable than Na+ in a resting neuron. This is because there are few sodium leakage channels. 6. Since the resting membrane potential is the potential difference between the inside and outside of the cell across the membrane‚ a change would depend on the resting permeability of the membrane to ions. Activity #2 1. 2. Graded potentials can be said to be momentary‚ localized changes in the membrane potential that can be either depolarizing or hyperpolarizing. 3. In the

Enzyme Controlled Reactions 1) Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction. Is this a linear relationship? What happens to the initial reaction rate as substrate concentration increases? A) The relationship between the substrate concentration and the initial reaction of an enzyme-catalyzed reaction is very productive‚ but is dramatically affected by the pH level of the given solution. The most productive pH level is

erical methPage 48 Licentiate Thesis / Nenad Glodic 6 NUMERICAL INVESTIGATIONS 6.1 Numerical Method Numerical simulations are carried out employing a commercial CFD code (ANSYS CFX v11). The solver is using a full-scale time-marching 3D viscous model. Underlying equations‚ three dimensional Navier-Stokes equations in their conservation form‚ are being solved by using a Finite Volume method‚ where equations are integrated over the finite control volumes. Thereby‚ the solution domain is subdivided

Introduction: The purpose of this lab was to measure the extent of enzyme reaction on given substrates by means of color change. The reaction followed is given below: Tyrosinase³ Enzyme Pyrocatechol Hydroxyquinone Oxidation/Reduction Pink ³ Brown E+S + [ES] = E+P Enzyme Reaction Hypothesis: If there is an increase in enzyme concentration‚ an increase in reaction temperature‚ or an increase in buffer pH‚ then greater

Enzymes are important components of life‚ facilitating reactions that are necessary for an organism to live. Enzymes can be very specific to what environment they function best in1. Numerous environmental impacts were tested for the enzyme peroxidase which catalyzes the decomposition of hydrogen peroxide. The basic decomposition reaction was carried out first without any environmental alterations. The hypothesis for this reaction was supported. The enzyme caused the amount of absorbance increase

How is a file identified? A file is often identified by the length‚ shape‚ cut and coarseness of the file. 2. What are the four different cuts found on files? The four different cuts found on files are single‚ double‚ curved tooth and rasp. 3. Name four coarseness designations for files. The four coarseness designations for files are rough‚ coarse‚ bastard‚ second cut‚ smooth‚ and dead smooth. 4. Which of the two kinds of files—single cut or double cut—is designed to remove more material?

The environmental factors that effected the rate of enzyme reactions were the enzyme concentration‚ pH‚ and temperature. These environmental factors help enzymes break down the poisonous chemicals into harmless substance. When we tested the liver with 2ml of hydrogen peroxide for a normal reaction it showed that it was exothermic. We added more hydrogen peroxide and the reaction rate of the liver was 3. We learned that the catalase is reusable because the liver reacted both times when we put in

IMP 2 POW 3: Divisor Counting. I. Problem statement: This POW is all about finding information and patterns about the way divisors of certain numbers are found and expressed. In this POW when we talk about divisors we usually are counting the number of divisors that a number has. The divisor is a number that a number can be divided by‚ of course every number is divisible by every other number but in these problems we are only talking about whole‚ positive numbers. Every number is divisible evenly

Enzymes are biological molecules (proteins) that act as a catalyst and help complex reactions occur everywhere in life‚ for example a piece of steak that is being digested into energy. Molecules found at the beginning of the process are called substrates‚ and these enzymes exchange them into differing molecules known as products. Nearly all-metabolic processes in a cell need enzymes in order to function at rates that are fast enough to sustain existence. Those who are lactose intolerant are simply
