Problem Set 1 1. Explain lipoprotein physiology and metabolism (Chapter 15). - Lipoproteins are a biochemical formation that aid with the transporting of lipids. The four major pathways include Lipid absorption pathway‚ exogenous pathway‚ endogenous pathway and reverse cholesterol transport pathway. All of these pathways are dependent on a particular particle know as apo-B that contains lipoproteins which‚ functions as a transport for dietary and Hepatic lipids to the outer layers of the cells

1. What is the molecular weight of Na+? 22.99 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through?50‚ 100 and 200 4. Which materials diffused from the left beaker to the right beaker Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because it is too large to diffuse Activity 2: Simulating Dialysis 1. What happens to the urea concentration in the left beaker (the patient)? Its concentration gradient

1) Make a graph of resting heart rates from Activity 1. Provide a physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate. The resting heart rate fluctuates over time because it is under control of the autonomic nervous system and the fluctuations are a result of the sympathetic and parasympathetic systems trying to balance each other out. There are many reasons

Hormones and Metabolism Activity 1: Determining the Baseline Metabolic Rates 1. Which rat had the fastest baseline metabolic rate? Normal rate 2. Why did the metabolic rates differ? Because of the different organs that were removed from the two other rats that would produce certain hormones 3. If an animal has been thyroidectomized‚ what hormone(s) would be missing from its blood? thyroxine 4. As a result of the missing hormone(s)‚ what would the overall effect on the body and metabolism

Aseptic Technique and Culturing Microbes‚ Lab #3 Purpose: The purpose of the this experiment is to learn to transfer microorganisms to a nutrient medium to promote growth using aseptic techniques. which are a method used to prevent unwanted organisms from contaminating a medium. We will also learn about different types of culture media‚ including MRS broth and nutrient broth‚ learn about oxygen and temperature requirements for microbial growth and how to control microbial growth. Procedure:

Equipment Calibration is defined as the act of adjusting and evaluating the precision and accuracy of measured equipment. It allows the user to get an accurate and precise reading of measurements to its actual true value. However‚ in order for the experiment to be effective is must consist of validity‚ reliability‚ and objectivity. Validity is defined as the ability of a test to measure what it claims to measure. Reliability is the consistency of test results and objectivity is defined as a test
