Design Experiment: Enzyme Inhibitors. Research question: What is the effect of adding lead nitrate solution on the activity of amylase enzyme? Aim: To test the effect of adding nitrate solution on the activity of amylase. Background Information: Inhibitors are molecules which repress or prevent another molecule from engaging in a reaction. They are substances that attach themselves onto an enzyme and reduce or prevent the enzyme’s ability to catalyse reactions. Competitive Inhibitors are inhibitors

Definitions and words have many misconceptions. Everyone views things differently. People of different races‚ age‚ sex‚ and religion may think differently than I would. Disagreements are common to encounter and stereotyping plays a huge role. One word that interest me the most is self-interest. While everyone has a different point of view on this word‚ I believe self-interest means more than what the dictionary states. When I think of self-interest‚ the first thing that comes to mind is one’s happiness

choosing the pain of discipline over the ease of distraction. And that’s exactly what delayed gratification is all about” I think that is very true. Delayed gratification is just waiting for something better. If a kid doesn’t pass the marshmallow experiment parents start to wonder what they should do. Mischel states he would remind the parents that there are a large number of cognitive skills that can be used and practiced if kids have a serious self-control problem.

Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic
