MICROBIOLOGY AND INDUSTRY - $7

Throughout the previous modules you have gained information on the methods used to distinguish different bacteria from one another. This activity serves to reinforce the concepts associated with biochemical tests, help you learn the metabolic strategies associated with individual or groups of bacteria, and strengthen your understanding of basic morphological differences. For this assignment, you are to choose one (1) of the groups, either A) oral/respiratory tract pathogens and commensals, or B) urogenital pathogens and commensals or C) gastrointestinal tract pathogens and commensals, and develop a key based on differential staining and culturing, morphology and the suite of biochemical tests available to identify bacteria.

Lab Enzymes UMUC Biology 102/103 - $10

Pre-Lab Questions 1. How could you test to see if an enzyme was completely saturated during an experiment? 2. List three conditions that would alter the activity of an enzyme. Be specific with your explanation. 3. Take a look around your house and identify household products that work by means of an enzyme. Name the products, and indicate how you know they work with an enzyme. Experiment 1: Enzymes in Food This experiment tests for the presence of amylase in food by using Iodine-Potassium Iodide, IKI. IKI is a color indicator used to detect starch. This indicator turns dark purple or black in color when in the presence of starch. Therefore, if the IKI solution turns to a dark purple or black color during the experiment, one can determine that amylase is not present (because presence of amylase would break down the starch molecules, and the IKI would not change color).

Osmosis.WEEK 3 EXPERIMENT ANSWER SHEET - $7

Experiment 3 Exercise 1 - Diffusion: Movement of Solutes across a Membrane Experiment 3 Exercise 2 - Osmosis: Movement of Water across a Membrane Experiment 3 Exercise 1: Diffusion - Movement of Solutes across a Membrane We will be using dialysis tubing to simulate a semipermeable membrane. This tubing allows small molecules (e.g., water, ions, glucose) to pass while preventing large molecules (e.g., macromolecules like proteins, starch, glycogen) from moving across. Be sure you have read over the suggested material before starting this exercise and that you have reviewed the following animations:
