On day 1 the teacher will have the students answer the pre lab questions included below and copy the data table from the lab sheet provided. On day 4 the students will be sharing their labs with their teacher via google docs so the teacher will be able to highlight and comment on areas of the lab Macromolecule lab that may need to be adjusted.
Proteins are optimised for catalysis[ edit ] Proteins are functional macromolecules responsible for catalysing the biochemical reactions that sustain life. RNA encodes genetic information that can be translated into the amino acid Macromolecule lab of proteins, as evidenced by the messenger RNA molecules present within every cell, and the RNA genomes of a large number of viruses.
It contains only the solvent usually distilled water and does not react in the test. The students will use the teachers feedback to improve their lab skills. What will the students and teacher do so students have opportunities to clarify their ideas, reach a conclusion or generalization, and communicate what they know to others?
Students will answer pre-lab questions, complete a lab, answer post lab questions, and write a paragraph including results and a paragraph including conclusions. Before the lab the teacher should read the MSDS of all chemicals being used in the lab. First, it is normally double-stranded, so that there are a minimum of two copies of the information encoding each gene in every cell.
The teacher will then ask students which macromolecules that they think each item contains. Proteins Proteins are versatile structural molecules found in all life-forms.
Potatoes blend in a blender and add water to liquify. Each of these tests involves two or more treatments: Hot plates, Benedicts indicator, iodine, buriet, paper bags, test tubes, test tube racks, MSDS Benedicts, iondine, buriet.
After discussions the teacher will then ask the guided questions. Carbohydrates Carbohydrates are molecules made of C, H, and O in a ratio of 1: We all know hamburger contains protein but how? Use the results of the known test reactions to identify macromolecules in unknowns.Macromolecule Lab.
Ravi Patel Proteins Table Biuret Test Tube Contents Final Color 1 Distilled water Transparent, light blue, navy. Title: Biological Macromolecules Lab Purpose: Cells, the fundamental units of life, are composed of various combinations of organic macromolecules: carbohydrates, lipids, proteins, and nucleic acids.
This lab exercise is designed to show you tests commonly used to detect macromolecules. Students will. Dive into the different types of macromolecules, what they are made up of, and how they are built up and broken down.
Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more. Here is an index guide to the Kirkwod faculty websites. They are listed in alphabetical order by last name. Not all faculty members have a website. Testing Macromolecules Lab p.
3 LIPIDS Lipids are nonpolar and therefore do not dissolve in water. cm of cream and 1 2. 3. Table 3. TEST TUBES Vegetable oil and Sudan IV after 1 minute Sudan IV and distilled water after 1 minute Sudan IV and beef broth Sudan IV and cream RESULTS SAFE POSITIVE FAT TEST: 1. Get four small pieces.
POST LAB QUESTIONS – Macromolecules Testing 1) Which macromolecules (or types of macromolecules) did you test for in this lab? 2) How did your hypothesis compare with your results? 3) Describe anything that might have affected your results (sources of error).Download
