Understanding ion permeability is vital to knowing how it establishes a membrane potential‚ and how it eventually leads to the contraction of muscle cells. This was done using crayfish tail muscles. Lateral and medial tail muscles from the tail of a crayfish were excised. These muscles were then placed into solutions with different types of ion concentrations. Usage of different ion concentrations was necessary in practicing how to measure resting membrane potentials accurately. Measurements with

temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed with detergent which foamed showing a visual display of the reaction. After 10 seconds

The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate of consumption of A = -[pic]rate of

Investigating travel and tourism industry There are 8 main components of travel and tourism industry. They are : 1- Accommodation- this is the most important component in the travel and tourism industry. Accommodation may include hotels‚ guest-houses‚ lodging-houses‚ bed and breakfast‚ inns and motels. 2- Transport- a good transportation system is very important for a travel and tourism industry‚ whether people are on business‚ travelling for leisure or visiting friends and

Introduction The purpose of this experiment was to determine the rate law graphically from the rate of disappearance and the x y values also the specific rate constant (k). Activation energy was also determined‚ and the effect of catalyst was evaluated in the reaction between peroxodisulphate ion S2O82-‚ and iodide ion‚ I-. S2O82-(aq) + 3 I-(aq) --> 2 SO42-(aq) + I3(aq) The general expression for the rate law‚ given this overall reaction‚ is: rate of disappearance of S2O82- = k[S2O82-]m[I-]n Chemical
