Experiment 10 – Enzymes Enzymes are proteins that act as catalysts for biological reactions. Enzymes‚ like all catalysts‚ speed up reactions without being used up themselves. They do this by lowering the activation energy of a reaction. All biochemical reactions are catalyzed by enzymes. Since enzymes are proteins‚ they can be denatured in a variety of ways‚ so they are most active under mild conditions. Most enzymes have optimum activity at a neutral pH and at body temperature. Enzymes are

Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the

The Asch Experiment How conformity influenced the world Megan Foster Many psychologists have performed experiments to prove theories and replicate actions. One of these most famous psychologists is Solomon Asch. In 1955‚ social psychologist Asch designed and experiment to show the effects of conformity in today’s society.

EXPERIMENT OBJECTIVE The aim of this experiment is synthesize hexaphenylbenzene via an aldol condensation reaction‚ followed by a Diels-Alder [4+2] cycloaddtion. This is final step in the multistep synthesis pathway to form hexaphenylbenzene‚ and uses the products of the previous experiments: benzil and diphenylacetylene REACTION DIAGRAM TABLE OF REAGENTS BENZIL DIBENZYL KETONE TRITON B 40wt% IN METHANOL (1.79 M) TRIETHYLENE GLYCOL TETRAPHENYL-CYCLOPENTA-DIENONE DIPHENYL ACETYLENE

Are you looking for a fun experiment that you can perform for a psychology class? This experiment on gender and memory is relatively quick and easy to perform‚ which is a bonus if you are short on time and resources. Could gender differences play a role in short-term memory? We often hear women complain that their husbands can’t remember important dates like anniversaries or birthdays‚ but could this phenomenon be due to something like memory differences between men and women.

This experiment brought uproar amongst the psychological world and caused the code of ethics to be reviewed and ultimately changed. In the experiment subjects were asked to administer shocks ranging from fifteen volts

Experiment 4A – Counting Atoms in a Chemical Reaction Purpose: The purpose of this lab is to create an experiment where zinc reacts with hydrochloric acid in order to find out the number of moles and atoms of zinc reacted. This can be accomplished by weighing the sample before and after the reaction with hydrochloric acid. Data: Material Mass in grams (g) Initial mass of dry beaker 49.37 Initial mass of dry beaker + zinc 51.03 Initial mass of zinc 1.66 Final mass
