Unit 1 Lesson 1 Key Question Biology SBI4U-C ILC 1) Mg2+ Has 10 electrons. 2) Carbon -14 would not be effective at dating bones that are millions of years old. Carbon -14 is effective at dating to a maximum of 40 000 to 50 000 years old. The isotope decays over time and would not be present on bones that are millions of years old. 3) Hydrolysis - Water used to breakdown molecules. Hydro means water and lysis means to breakdown. An example of hydrolysis in action within our bodies is how our

Carrot juice (1) INTRODUCTION to the topic Fermentation is the slow decomposition of complex organic compound into simpler compounds by the action of enzymes. Enzymes are complex organic compounds‚ generally proteins. Examples of fermentation are: souring of milk or curd‚ bread making‚ wine making and brewing. The word Fermentation

Enzyme activity The introduction is a statement of the subject and objectives of the experiment and presents your hypothesis. Relevant background information (appropriately referenced) is given in sufficient detail that a person unfamiliar with the topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase

Title: Enzyme Catalysis of Hydrogen Peroxide by Catalase Problem and Objectives: How do different temperatures and different levels of pH affect the reaction rate of the enzymes in chicken liver? Demonstrate the activity of an enzyme in living tissue‚ observe the effects of changes in temperature and pH on the activity of an enzyme‚ perform analyses for the presence of an enzyme in tissues‚ and analyzing relationships between environmental conditions and enzyme activity. Background: Cells produce

Lab Report An enzyme is a protein that speeds up the rates of chemical reactions. They recognize‚ bind‚ and change specific reactants. They do not change so they can catalyze the same reaction again and again. Activation energy is the amount of energy needed in order to begin a chemical reaction. A Catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Catalysts are substances or a substance that configures another substance

The four types of biochemical reactions studied in this lesson are: Hydrolysis: This biochemical reaction is important because it helps to break down molecules such as; food consumed. A person required water and enzymes to break down food. The reaction is: protein + water = amino acid + amino acid Condensation: Occurs when two molecules combine to form one molecule. This biochemical reaction is known as dehydration synthesis because water is removed from the molecule
