macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda solution. These controls

Lab: Cellular Respiration in Yeast Lab Report Form Your Name: Katlin Moore “What do you think? – What do you know?” Questions: In this lab‚ we will investigate the effect of sucrose concentration on the rate of cellular respiration in yeast. Under specific conditions‚ yeast will convert sucrose into glucose and then use this glucose in cellular respiration. Yeasts have been used by humans in the development of civilization for millennia. What is yeast? How have humans used yeasts?

Enzyme Activity Lab Objective: To determine the effect of temperature‚ PH and enzyme concentration on catalase activity. Introduction: What is an enzyme and how the enzyme works. Any of a group of complex proteins or conjugated proteins thatare produced by living cells and act as catalysts in specific biochemical reactions. The system in which enzymes work is often referred to as the ’lock and key’ system it’s where the enzyme and the substrate lock together. The substrate then unlocks into

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Standard Solution (Part A and B) ABSTRACT The purpose of this experiment is to prepare a standard solution of potassium hydrogen phthalate and use titration to perform an acid/base reaction between the potassium hydrogen phthalate and sodium hydroxide to standardize approximately 0.10 M sodium hydroxide solution. To prepare the Potassium Hydrogen phthalate‚ a 2.00 grams of KHP was measured to an accurate measurement of 1.980 grams. A total of 100 mL of water was mixed with the KHP solution in the

Abstract— Omega-3 chicken egg is a chicken egg that produced by hen which was feed with high omega-3 fatty acids. Therefore‚ the content of omega-3 in omega-3 chicken egg fifteen times higher than leghorn egg. Omega-3 chicken egg has a shape and color similar to leghorn egg. It is difficult to differentiate both of eggs just by looking at the shell. Observing this problem‚ an experiment is held to differentiate between omega-3 chicken egg and leghorn egg using image processing method based on Android

cholesterol contained in eggs. But‚ the real truth is that eggs‚ just like many other foods‚ such as: coconut oil or avocados‚ eggs were mistakenly thought to be bad for your health. Really‚ the egg yolk offers a lot of supplements and medical advantages. Up to 90% of the egg’s calcium and iron are situated in its yolk‚ which makes it absolutely sound and prescribed. Then again‚ the egg white offers some characteristic proteins‚ additionally huge for the human living being. And the egg white contains almost

Mixtures and Solutions can often become confusing because solutions are mixtures‚ but not all mixtures are solutions. A mixture can either be homogeneous or heterogeneous. A homogeneous mixture is where the mixture’s components are distributed uniformly within the mixture. A heterogeneous mixture is where the components are not uniform. Mixtures can either be miscible or immiscible‚ the difference being whether or not the mixture forms a homogeneous mixture or not. In a solution a solute is soluble

This assignment must be submitted no later than November 22nd‚ 2011. 1. What is a true solution? Explain why the solute does not settle out of a solution. Is it possible to have one solid dissolved in another? Explain. In metals it would be called an alloy. 2. An aqueous solution of KCl is colorless‚ KMnO4 is purple‚ and K2Cr2O7 is orange. What color would you expect of an aqueous solution of Na2Cr2O7? Explain. Orange. 3. Explain why hexane will dissolve benzene but will not dissolve
