Cell Membrane Transport The purposes for these experiments is to be able to understand osmosis and its relationship to tonicity of solutions‚ and the transportation of molecules across cell membranes. It’s also used to understand‚ and how temperature affects diffusion. You also learn how to test for presences of starches and sugars in solutions. In the first exercise I will be testing for diffusion through an artificial membranes. This one has forty five steps to it. I will not go into

Review Sheet Results 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare

PhysioEx – Exercise 9 Activity 1: 1. excretion and regulation 2. glomerular capillaries (glomerulus) & Bowman’s capsule 3. The filtrate flows from the Bowman’s capsule into the renal tubule called the proximal convoluted tubule then into the loop of Henle‚ and finally into the distal convoluted tubule: a. Proximal Convoluted Tubule b. Loop of Henle c. Distal Convoluted Tubule 4. When the radius of the afferent arteriole was decreased‚ the pressure and the filtration rate both decreased

Exercise 6: Cardiovascular Physiology Worksheet Assignment Due: Week 6 Electrical Stimulation Activity 1: Direct Heart Stimulation 1. Did you see any change in the trace? I did not see a change in the trace 2. Why or why not? This is because it needs more stimulation 3. Did you see any change in the trace? I did see a change in the trace 4. Why or why not? This is because there is double stimulation. 5. Describe the change you see in the trace. How does it differ from the baseline

Cell Transport And Homeostasis The roles of different types of cell-membrane proteins in the preservation of body organs donated for transplant is very vast. Certain cell-membrane proteins carry several different types of nutrients that are beneficial and are sometimes very important to keep organs that are to be transplanted healthy and fresh. Organic nutrients are some very good preservers. One of the most transplanted organs is the kidney. It is important that this organ has nutrients
