Understanding the Functions of Proteins and DNA Ingrid Waldron‚ Biology Department‚ University of Pennsylvania‚ 2012 These key concepts and activities are suggested as part of an introductory unit on biological molecules (or as an introduction to a unit on molecular biology). The overarching goal is to help students understand that proteins and DNA are not just abstract concepts in biology textbooks but rather crucial components of our bodies that affect familiar functions and characteristics

Abstract An experiment is conducted to prepare soap and thus‚ to compare the properties of the prepared soap and synthetic detergents which are precipitation‚ emulsification and cleaning abilities. It can be concluded that soap has the properties if emulsifying oil whereas detergent has not. The abilities of forming precipitates can be seen clearly in soap solution whereas detergent forms no precipitates at all. The experiment is completed and successfully conducted. Introduction

Heat & Mass Lab 1: | | | 2/10/2011 2/10/2011 Executive Summary This experiment was conducted using a heat transfer unit. Many relationships were obtained and calculated from the observed results. To name a few; the log mean temperature difference‚ heat transfer coefficient‚ Reynolds‚ Nusselt and Graetz numbers. The main focus of this experiment is the heating and cooling of the oil fluid. This was achieved using the heating component in the heat exchanger and water flowing

They also remain unchanged after use‚ which enables it to be used repeatedly. Cells have special catalysts called enzymes‚ which are specialized proteins that help accelerate chemical cell reactions. (Evert‚ RF & Eichhorn‚ SE 2013). Enzymes also control plant metabolic processes such as respiration (Evert RF‚ Eichhorn SE & Perry JB 2013). This experiment focuses on the enzyme catalase. Catalase breaks down hydrogen peroxide into water and oxygen. Hydrogen peroxide is a waste product of cell metabolism

17 May 2013 Are Protein Shakes Good For You? According to Flex bodybuilding magazine‚ protein shake is the number one selling bodybuilding supplement. Protein powders have been around for years‚ but they are currently gaining popularity and becoming more widely used for their health benefits. In fact protein is one of three food components we require in large quantities. Others are carbohydrates and fats. Your body uses proteins in your diet to build new cells‚ maintain tissues‚ and synthesize

This lab report is not perfect‚ but can serve as a guide in understanding how to write one! Introduction Insulin‚ an amino-acid based protein‚ helps make up a larger polypeptide chain‚ proinsulin‚ which is located within the beta cells of the pancreas. Enzymes release the insulin from the larger proinsulin chain just before it is secreted from the beta cells. Insulin’s main function is to lower blood glucose levels by speeding up the membrane transport of glucose from the blood and into

Natalia Wierzchon A.P. Biology Lab: 1. Osmosis 09/10/2010 I. Introduction a. Purpose: The purpose of this lab was to observe the diffusion process of water‚ osmosis‚ as well as create an understanding of water potential‚ the basis of osmosis. The experiment proved how water molecules in a solution are able to move from an area of low solute concentration‚ high water concentration‚ to an area of high solute concentration‚ low water concentration‚ diffusing “down” the water gradient.
