Abstract: After reviewing the basics of enzymes and catalysis‚ we take a dive into the wonderful world of catalase. Beginning with establishing a base line of just how much hydrogen peroxide there is in 5.0mL of the reacted solution; to figuring out exactly how much actually reacted after 300 seconds of catalyzed reaction. Follow the experiment from the beginning steps right to the end as you see where the students went wrong‚ interpretation of the results‚ and great answers to work sheet

Apollo 13 The movie Apollo 13 is a true story about a failure of a space mission to the moon. Before they end up getting to the moon‚ something goes wrong with the rocket ship. The quote “We just put Sir Isaac Newton in the driver’s seat” from the movie Apollo 13 is figure of speech. A figure of speech is an idiom‚ metaphor‚ or simile. In this case‚ the quote is an idiom. An idiom is a figure of speech that is meant not to be taken literally. It’s raining cats and dogs is an example of an idiom

Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The

“The Effect of Level of Activity on Clothespin Squeezing Amount Question: Does exercising/ resting affect the number of times you can squeeze a clothespin in a minute? Hypothesis: If the person DOES NOT exercise before the task then‚ they will be able to squeeze the clothespin more because not exercising/resting allows the body to relax and there are no buildups of waste products. Biological Explanation: Both the respiratory system and the circulatory system are involved within my experiment

Ah Seung Chong Molecular Biology CTW: Enzyme Kinetic Dr. Cruz 07/22/2010 Enzyme kinetics Introduction Enzymes are biological catalysts or assistants‚ without enzyme many of important processes of life could not happen. Most of enzymes are proteins that help speed up chemical reactions by lowering amount of activation energy needed for the reaction1. Enzymes are usually highly selective‚ only bind to specific substrate and convert it to product at a particular rate1. The rate of the reaction
