Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work

Bilal Said Mrs. Henderson AP Biology; P: 1 September 1‚ 2013 Doubled Stuffed Oreos? Introduction and Hypothesis: When in your in a store‚ there are two different sized of Oreos to choose from‚ either the regular Oreos or the doubled stuffed Oreos. Is the doubled stuffed Oreos really double the stuffing‚ if so it may be a good deal to spend a little extra? We want to know if the Oreos are worth its deal. We know that the DSO (double stuffed Oreo) is taller than the regular Oreos. We will soon

Molecules of Life 4 Critical large Molecules- 1.) Carbohydrates 2.)Lipids 3.)Proteins 4.) Nucleic Acids -On the molecular scale‚ members of three of these classes--- Carbohydrates‚proteins‚ and nucleic acids--- are huge and therefore called Macromolecules. - Architecture of a large biological molecule helps explain how that molecule works. ---------------------------------------------------------------------------------------------------------------------------- Macromolecules

1. Who sang at the Grammy’s in Spanish in the late 1990s? What was the reaction? Ricky Martin shocked the audience by singing in Spanish at the 1990’s Grammy Awards. Eventually‚ the audience gave Martin a standing ovation for his brilliant song. 2. When did Latin music burst back on the scene? What song brought it back to the mainstream? What effect did it have? Latin music came back onto the scene 15 years before Ricky Martin’s performance with Gloria Estefan’s “Conga”

Taylor Hill Lab 6: Enzymes Purpose: The purpose of this lab is to test for enzyme activity‚ look at enzyme specificity‚ and how temperature affects enzyme activity. Hypothesis: I believe that the room temperature activity will produce the most activity. Materials: 3% hydrogen peroxide‚ a household blender‚ potatoes (3 medium size potatoes‚ that are peeled and quartered)‚ tap water‚ 8 test tubes‚ 8 transfer pipets‚ sugar packets‚ salt‚ a small saucepan‚ a refrigerator with a freezer‚ stove

Andrews July 13‚ 2013 * * * * Abstract: In this laboratory we utilize simple measures of physical quantities (for example‚ distance‚ and mass) and use the measurements to calculate or convert other physical quantities (such volume and area). We also use mathematical calculations and formulas to make conversions from one unit of measurement into another unit of measurement (for example‚ a

1. Why are spindle fibers important for mitosis? (5 points) Spindle fibers work as a path for chromosomes to travel(Campbell‚ 2009). 2. State the four bases that make up DNA. (4 points) a. (A)-Adenine b. (G)-Guanine c. (T)-Thymine d. (C)-Cytosine (Campbell‚ 2009). 3. What are the two base pairs? (2 points) a. AG b. CT 4. Answer the following questions: a. Define the term crossing over. (3 points) The phase in meiosis where chromosomes exchange segments of genetic materials (Campbell‚ 2009). b. Explain

was then used to transfer 4ml of anhydrous ether to the vial. The syringe was then utilized to transfer 0.8 ml of this solution and the reaction was allowed to proceed until the solution turns brown and cloudy. The conical vial was then rinsed with 2 ml of anhydrous ether to get any remaining solution into the reaction vessel. Simultaneously‚ 1.09 g of benzophenone and 2ml of anhydrous ether were added to a 3ml conical vial and gently stirred. The reaction vessel was taken off of the hot plate and

Describe their role in the process. Pollen is produced in the stamen. Pollination occurs when that pollen is transported from the anther to the style by insects or animals that are attracted to the plant by the beautiful petals of the flower. 2. Which parts of the flower are involved in fertilization and fruit development? Fertilization starts after pollination has occurred‚ and begins inside the pistils. The ovule contained inside the ovary is fertilized and the ovule begins to harden and

Light Microscopy Lab Lab write-up 1 Parveen Rajper Biology 101 Principles of Biology 1 September 29‚ 2012 Introduction: The light microscope helps see the microscopic world that the naked eye cannot see. If there were no microscopes in the world‚ than it would be very difficult to understand the many particles that surround the living world. The purpose of this lab experiment is to become familiar with a microscope. It is hypothesized that it will be difficult
