Lab Report #1 Introduction A cell’s plasma membrane is known to be selectively permeable. This implies that the membrane is selective on what substances can pass in and out of the cell. There are two methods of transport that occur through the plasma membrane. One method of transport is called active process which uses ATP energy to transport substances through the membrane. The other method is called passive process which does not require the use of ATP energy. During passive processes

form of urine‚sweat‚urea or bile. This is important so as to help maintain balance within the organism and prevent damage to m the body. As your body performs the many functions that it needs in order to keep itself alive‚ it produces wastes. These wastes are chemicals that are toxic and that if left alone would seriously hurt or even kill you. For example‚ as your cells break down amino acids‚ they produce a dangerous toxin known as urea. The cells of your body excrete this urea into your blood

Materials & Methods Materials: Online Pearson ’s Lab. Methods: Follow the steps and procedures laid out for me. Results Experiment Results Predict Question: Predict Question 1: The molecular weight of urea is 60.07. Do you think urea will diffuse through the 20 MWCO membrane? Your answer : a. Yes‚ but very slowly. Predict Question 2: Recall that glucose is a monosaccharide‚ albumin is a protein with 607 amino acids‚ and the average molecular weight of a single

Activity 1: 1. Did any solutes move through the 20 MWCO membrane? Why or Why not? 2. Did Na+Cl- move through the 50 MWCO membrane? Activity 2: 1. Are the solutes moving with or against their concentration gradient in facilitated diffusion? 2. What happened to the rate of facilitated diffusion when the number of carrier proteins was increased? 3. In the simulation you added Na+Cl- to test its effect on glucose diffusion. Explain why there was no effect. Activity 3: 1. Which membrane resulted

viscosity of the prepared native‚ blank‚ denatured native and blank with denaturant solutions. The time required for the said solutions to pass through the viscometer were recorded and their viscosities were then calculated using the data. Experimentally‚ urea was found to be the best out of the six denaturants that were used. Results and Discussion Proteins differ from each other by means of the amino acids that it contains. Each protein has its own biological function based on the way its components

Virtual Lab Unit 3 1. Briefly describe the steps required to aseptically transfer bacteria from an unknown to a tube of liquid broth. You might have to research this using the "T" button (Tell Me More About...) To aseptically transfer bacteria from an unknown to a tube of liquid broth you have to flame the loop or wire before you begin to sterilize it. You then remove the caps from the tubes and flame the mouths of the tubes to prevent air-borne contamination. When all this is done‚ you have to
