3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? I predicted that only glucose would diffuse through it and was right. Albumin is too heavy to diffuse through that membrane. 4. Put the following in order from smallest to largest molecular weight: glucose‚ sodium chloride‚ albumin‚ and urea. NaCl‚ Urea‚ Glucose‚ Albumin Activity 2 Simulated Facilitated Diffusion 1. Explain one

but in some forms it does share likeness to it. All of this inward and outward traffic is controlled by the Plasma Membrane. The Plasma Membrane is the outermost layer of the cell‚ and consists mostly of a phospholipid bilayer‚ but also houses some proteins and other substances to aid in the crossing through the membrane.

conducted to see if the potato cylinders would gain weight or lose weight because of osmosis. The second part was conducted to see if a dialysis bag‚ filled with sodium sulfate and starch solution and placed in an albumin/glucose solution‚ would contain albumin/glucose from the outside or the albumin/glucose solution would contain any sodium sulfate/starch from the inside. The first part of this experiment there is a relationship between the amount of sucrose concentration and final mass. As the sucrose

Curve and Determining Unknown Protein Concentrations Introduction: In biochemistry the ability to determine the quantity of a certain substance in a solution is extremely important. Often protein concentration within a biological organism is essential in determining the function or condition of that organism. If the protein concentration in an environment is increased or decreased it can have detrimental side effects. If there is a decrease in hemoglobin (a protein found within blood)‚ oxygen

Introduction: Proteins are polymers that are made up of smaller units/monomers called amino acids. There are 20 different types of amino acids‚ thus make up many different combinations in types‚ numbers of amino acids as well as their orders – an explanantion for why there are so many proteins. Every protein‚ due to various reactions of amino acids to each other‚ have its own three dimensional structures and therefore‚ function (Reece JB and others 2011). Proteins are fundamental substance

Extraction of DNA from Calf or Hog Thymus/Isolation of Yeast RNA I. Abstract Nucleic acids may be divided into two groups RNA and DNA. DNA contains almost all the genetic information while RNA serves as the bridge between the DNA and proteins. Study of both DNA and RNA initially involves proper extraction/isolation. The storehouse of eukaryotic DNA is the nucleus (and in the mitochondria)‚ so experimentally‚ DNA is extracted from tissues that have a high nuclear to cytoplasmic mass ratio‚ such

The first article reviewed is ‘Post exercise net protein synthesis in human muscle from orally administered amino acids’ by Kevin D. Tipton et al‚ published in the ‘American Journal of Physiology – Endocrinology and Metabolism’ in 1999. The study conducted examined the effects orally administered amino acids post resistance exercise has on protein synthesis and metabolism. The reason this study was conducted was to determine if taking amino acids orally‚ which is easily done‚ is just as effective
