travels down the T-tubules of the sarcolemma‚ which then activates the release of Ca++ . The Ca++then binds to troponin triggering the movement of tropomyosin away from its blocking position at the myosin and actin binding sites. The binding and hydrolysis of ATP to the myosin head produces changes‚ causing the filament to slide against the myosin filament and the sarcomere to shorten (Johnson 37-38).

powerful activating group‚ which allow the procedure to go without a catalyst. The bromination of the acetanilide gives the tribromide instead of 4-bromoaniline. preparing the 4-bromoaniline involves the attack of a strong electrophile and the hydrolysis of a proton to give the final product. Chemicals and Safety: Bromine is very poisonous‚ and can cause burns. Eyes‚ skin and nose should be protected while carrying the bromine inside the hood. Glacial acid is also a very corrosive compound

nExperiment C: Kinetics of the Hydrolysis of T-butyl Chloride Post-Lab Ch202 Postlab Assignment Nov 5/2014 L10 Radwan Ahmed 130770850 1. What was green about this experiment was that the solvents used (acetone and water)‚ and even the tert butyl chloride were fairly safe to handle with respect to the other chemicals used in the lab. This is why gloves were not worn‚ and one reason why this experiment follows GCP # 3 where chemical products should be designed to preserve efficacy of the function

The Effect and Rate of the Enzyme Amylase on Starch Abstract Assessing reaction speed of the enzyme amylase can be measured by the amount of glucose and maltose produced during given time intervals. I hypothesized that‚ if the reaction time is longer‚ then the amount of amylase will be larger. Enzymes are specific in their match of substrates they will breakdown – similar to a key and its lock. Since amylase is the only enzyme that breaks down starch‚ the procedure was effective and gave clear
