Campbell’s Biology‚ 9e (Reece et al.) Chapter 5 The Structure and Function of Large Biological Molecules In Chapter 5‚ the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers‚ and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure‚ because this is central to understanding subsequent

Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

Carbohydrates are molecules composed of carbon‚ hydrogen‚ and oxygen; the ratio of hydrogen atoms to oxygen atoms is 2:1. Simple carbohydrates‚ commonly referred to as sugars‚ can be monosaccharides if they are composed of single molecules‚ or disaccharides if they are composed of two molecules. The most important monosaccharide is glucose‚ a carbohydrate with the molecular formula C6H12O6. Glucose is the basic form of fuel in living things. It is soluble and is transported by body fluids to all cells

The use of positive and negative controls to determine the macromolecules present in an unknown solution Course # 6130‚ Wednesday‚ 7-10 PM‚ B2-151 Lab performed: September 21st‚ 2011 INTRODUCTION Every living thing is dependent on large complex molecules‚ known as macromolecules. The objective of this lab was to correctly identify which macromolecules the unknown solution was comprised of using various substances as experimental controls. There are four major types of biological macromolecules

A. Polymers-the largest of the macromolecules. These are composed of numerous‚ small identical subunits known as Monomers. There are 4 major polymers that are important for living organisms. These polymers are; carbohydrates‚ lipids‚ proteins and nucleic acids. B. Polymers

Chapter 1 Cell Theory- in the 18th century‚ two scientists came up with the cell theory. Schleiden and Schwen. 3 corollaries of the cell theory: -all cells are alike in chemical composition -all cells store and process information in the same way -all cells arise from other cell through cell division 5 types of different Microscopes 1.
