Simple activity for practicing enzyme rate of reaction word document file be sure that you have an application to open this file type before downloading and/or purchasing. Lab report help please i am a sophmore doing a lab called toothpick lab to learn about enzymes the toothpicks are called 'toothpickase' just for fun purposes, i guess i have to write a lab report on it can anyone help me with suggestions for the intro, conclusion, or maybe the questions if u have done this lab. Ap lab 13 - enzymes: toothpickase lab date: 1092014 purpose: the effect of different conditions on enzyme activity conclusion: denatured, ice water and paperclips were conditions used to show enzyme efficiency while ice water and paper clips did not affect the enzyme's reaction rate greatly, a denatured enzyme was unable to function.

Enzyme reaction rates using toothpickase class set of directions background: enzymes are agents that change the rate of a reaction without being changed themselves. Enzyme simulation: toothpickase experimental question: how does the shape, temperature and substrate concentration affect enzyme functionality introduction: enzymes are proteins made by living cellsthey act as catalysts and affect the rate of a chemical reaction. Lab report design (d) provide a hypothesis for what will happen to rate of the enzymatic reaction as various factors are introduced to influence this rate. Introduction section in lab report for toothpickase part should address: 4) describe what the toothpickase simulation represents 5) place table 1 from this h/o here.
Temperature time to break 10 toothpicks (seconds) room temperature toothpickase cold toothpickase 1 how does temperature affect the time in which toothpicks are broken by toothpickase conclusions what is an enzyme what is the enzyme is this activity toothpickase activity. Toothpickase lab do not write on this handout background: enzymes are proteins that act as catalysts catalysts act on a specific substrate and usually cause a chemical reaction to occur more quickly enzymes can increase the rate of a chemical reaction by lowering the amount of make a note in your lab report what role you will. Toothpickase lab sheet, each person at your table will have a specific role in determining the efficiency of a particular enzyme at this time, i will give you five minutes to read through the lab yourself before the toothpicks in your “up ” and report them to ms svoboda at that time, i will bring you the necessary toothpicks you will. Toothpick biochemistry: toothpickase name _____ introduction: enzymes are proteins that are used as catalysts in biochemical reactions a catalyst is something that controls the rate of a reaction without itself being used up.
Mrs ring 3rd period toothpickase lab problem: how does changing enzyme concentration or temperature affect the reaction time of enzyme activity hypothesis: if an enzymes optimal working condition is altered, then the rate of enzyme activity will change because enzymes have optimal levels at which they function best. Enzyme lab 1 mitchell t heaton introduction: this lab is an analogy for the reactions and processes that occur when enzymes and substrates bind the experiment will show you how, when various situations occur, enzymes’ reactions increase and decrease this real life example of enzymes will show you exactly how they work by explaining them in a simple way. Toothpickase enzyme lab simulating enzyme activity under various conditions conducted in 2010 by the biology students at southfield christian school, southfield, michigan, usa.
