The Effect of Enzymes on Apple Juice Production Biology Period 6 Background Info The purpose of this experiment was to determine which enzyme or the combination of the two enzymes makes the most apple juice from applesauce. We did his by‚ mixing 10 drops of an enzyme (cellulose/pectinase/both) into a few tablespoons of applesauce. We then left the rest to nature‚ and watched the liquid funnel out for 10 minutes. Lastly‚ we recorded our data. The cell wall is a complicated

Again‚ small bubbles formed; intensity of (1). The solution did not change in temperature. The reaction lasted about 15 minutes. 3. After adding more manganese dioxide‚ the reaction occurred again. This time‚ the bubbles being formed were larger; intensity of (4). The solution got a little warmer‚ but the difference in temperature was hardly

Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For an example‚ “amylase is an enzyme

Introduction: Skeletal muscle is a type of striated muscle that is attached to skeleton to facilitate movement by applying force to bones and joints through contraction. Skeletal muscle generally contract voluntarily when stimulated by the nerve‚ although they can also contract involuntarily at times. Muscle action is controlled by the Nervous System

Introduction For this experiment‚ we are going to determine the effect of temperature on solubility‚ to be done in a chemical by dissolving a solute in a definite amount of solution which is saturated. Specifically‚ the goal of this experiment is to prepare a saturated solution of Na2C2O4 in water at different temperatures‚ determine the effect of temperature in solubility‚ and to apply Le Chatelier’s Principle. We can do all this by simply titrating a certain amount of standard KMnO4‚ and measuring

The effect of temperature on a reaction rate In this experiment I shall be investigating how temperature affects the rate of reaction Rates of reaction The Factors that affect the rate of reaction are temperature‚ surface area‚ concentration‚ catalysts‚ light and pressure Surface area – Surface area is the amount of solid surface that is available for reaction - Only affects solids so this will not affect our

catalyst is called biological catalyst‚ and enzyme is an example of biological catalyst. Enzyme is very important for biochemical reactions‚ as it helps the reaction to become faster than usual. The reactions with enzymes will react 10 billion times faster than those solutions without enzymes. (clitoncc)The enzymes can only react with one particular reaction‚ in order for the reaction to react it needed to find the correct enzyme.
