Properties of Enzymes and Competitive Inhibitors. Abstract: Properties of enzymes were found in this experiment and some other factors‚ which affect enzyme activity. Enzymes are catalyst; they catalyze very specific reactions. Results relating to the active site of specific enzymes played a big role while performing this experiment. The purpose of this experiment was to fin how inhibitors affect enzyme’s activity by competing for the active site against substrates. Introduction: Cells have the

There are competitive and non-competitive inhibitors. Both of them slow down the reaction. Competitive inhibitors are molecules that are shaped a lot like the substrate. They bind to the active site and stop the substrate from connecting. Non-competitive inhibitors connect to the enzyme in a place that is not the active site. Causing the active site to change shape. Inhibitors and catalysts are both used in everyday life. One example of how catalysts are used in everyday life is that catalysts

Relationships and Aging: Jenkins Question Socioemotional selectivity theory proposed that throughout early to late adulthood‚ people are more selective in their relationships to maximize gains and minimize risks. Instead of trying to pursue new experiences‚ one focuses on activities and relationships that have more emotional importance. This theory is based largely on the perception of time‚ which changes with age. Socioemotional selectivity has a large bias toward a positive outlook. People with

1. What is a COX-2 inhibitor? Why is it named so? How does it differ from COX-1 inhibitors? (3) COX-2 inhibitors are drugs used to treat inflammation. An example of a COX-2 inhibitor would be Celebrex. They are named COX-2 inhibitors because they inhibit cyclooxygenase-2 (COX-2) which is the enzyme responsible for inflammation. COX-2 inhibitors only affect inflammation while COX-1 would affect both inflammation and gastric acids in the stomach. COX-1 could lead to stomach issues with prolonged use

Date: 14th-15th October Title: The effect of the concentration of hydrogen peroxide on catalase Aim: to examine how the concentration of the hydrogen peroxide affects the rate of reaction Hypothesis: The substrate concentration will determine the rate of reaction. The reaction will increase as the concentration increases‚ but from a certain concentration‚ the rate will maintain the same rate Materials: 3% hydrogen peroxide 6% hydrogen peroxide catalase round metal basin measuring cylinder

September 2013 Acting is a Drug‚ and I’m Addicted When that spotlight hits your face‚ it is a better feeling than going to the beach on a breezy day. The feeling of nerves radiating throughout your body while you have the entire audience’s attention is exhilarating. There is no other feeling like it. I chose acting because I have been in plays for competitive and fun since I was eight years old. I started off in small church plays and worked my way up to larger competitive acting that went all the

Presentational acting and the related representational acting are basic terms utilized inside of theatre feel and feedback. Because of the same terms being connected to certain ways to deal with acting that negate the more theatrical definitions‚ in any case‚ the terms have woken up. In the most widely recognized sense (what relates the particular elements of theater to the more extensive tasteful classification of ’representational craftsmanship’ or "mimesis" in show and writing)‚ the terms portray

Respect for Acting: Part One After reading the first part of Respect for Acting by Uta Hagan I have a newfound respect for actors and all that they go through to obtain the true character in which they are playing. As someone who has never neither acted nor read anything about performing‚ this has opened my eyes to all of the work that these actors go through on a daily basis for the sheer enjoyment of their audience. While reading over the chapters in this book there are a few key concepts that

of actor has always intrigued me and I believe this would be a great opportunity to learn more about the field. To research acting I would have to go to a performance or go on a set of a production that a theatrical performance is taking place. Currently I’m studying acting for film and television at Relativity School as an acting major. I have learned much of the art acting since attending the school and how the field work‚ but I think I will learn more about what actually happens if I go on set
