Jennifer Anatomy and Physiology Enzyme Lab Report Introduction The chemical reaction that is being studied is the hydrolysis of starch. The enzyme that is being studied is amylase. This experiment is looking at the effect of temperature on the rate of the enzymatic hydrolysis of starch. My hypothesis is that the higher the temperature the faster the hydrolysis of the starch would occur. The rationale behind this is that heat

larger; intensity of (4). The solution got a little warmer‚ but the difference in temperature was hardly distinguishable by simply touching the test tube. The reaction lasted about 10 minutes. 4. a) The hydrogen peroxide is used up and the manganese dioxide remains unchanged. Part two Title: Enzyme Function Purpose: To observe the role of enzymes in chemical reactions and to determine the kinds of cells that contain more of the enzyme catalase. Prior Knowledge: Enzymes are proteins that assist

Misael Acosta Photosynthesis Lab Report Ms. Rocha AP Biology 4th Period II. Intro/Background 1. In order for oxygen to be present photosynthesis must occur. Photosynthesis takes in light and CO2‚ and through a series of steps produces oxygen. Photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. Examples include the production of O2 or the consumption of CO2. All the oxygen within the leaf disks will be removed before being placed

Why are some colors of light more effective than other colors? Answer Photosynthetic saturation is the maximum rate of photosynthesis. What was the value for photosynthetic saturation in tomato leaves? Answer Light quality does not effect the rate of photosynthesis. Answer Based on what you know about photosynthesis‚ provide possible reasons for what causes photosynthetic saturation (these cannot be determined from the graph). Answer Which color

Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein‚ which is capable of starting a chemical reaction‚ which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives‚ grows‚ or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

Middle Childhood Development and Personality Jessica Saar PSY/103 September 10. 2012 Donna Litteral Developmentally‚ middle childhood is a big time in a child’s life. During this time‚ they begin their academic journey. They are growing and changing in so many ways. Children begin learning how to relate to others outside the home. They also learn to respect others and how to treat others properly. A child’s physical and cognitive development can be affected by many things. Genetics‚ nutrition

Introduction: Living‚ microscopic‚ unicellular organisms can be identified as microorganisms. Fungi‚ Protista‚ Bacteria‚ and Archaeans are four kingdoms in the phylogenetic tree of life that consist of microorganisms. Amongst these microorganisms the prokaryotes were the first ones to arrive through evolution. The rest of the life forms as we see them evolved from these simple creatures‚ prokaryotes. The smaller prokaryotes were swallowed by bigger prokaryotes setting the stage for the origin of
