Transcript Of The Effect Of Amylase On Starch Concentration Biology Assignment

274 words - 2 pages

In conclusion, the results were the same as hypothesized, with higher concentrations of amylase resulting in faster starch breakdown. This can be seen, as the 5% amylase broke down the starch more than the 1% amylase. Sources of error may include incorrect measurements of starch or amylase.

The experiment was conducted in order to find how amylase concentration affects the rate of starch breakdown from its polymer state to its monomer (glucose) state. The rate of break down of starch by the amylase should determine how differing concentration affects the rate of hydrolysis. This was carried out by combining varied amylase concentrations with starch.

1. Measure 5 mL of starch with pipette and add into 4 test tubes.

2. Add 3 drops of iodine to each and mix

3. Label the other test tubes 1,2,3,4,and 5. Add 5 mL of 1% amylase to tube 1.

4. Mix and record the colour change. 

5. Repeat step 3 with all test tubes using the 3%...

Effect of Concentration on Osmosis Essay

2617 words - 10 pages Effect of Concentration on Osmosis Aim To find out how the concentration of sucrose solution affects the mass of the potato chip left in the solution for one day. Prediction I predict that when the sucrose concentration is low the potato chip will gain mass. This is because there will be a higher sucrose concentration in the potato chip so water will go into the potato from the solution. I predict that when there is a high

The Effect of pH on the Activity of the Enzyme Amylase

1658 words - 7 pages The Effect of pH on the Activity of the Enzyme Amylase Aim :- To find the effect of pH on the activity of the enzyme amylase. An enzyme is a type of protein found in all living cells. Enzymes act as biological catalysts, breaking down substrates without needing a high temperature, allowing all the chemical reactions of metabolism to take place, regulating the speed at which they progress, lowering the activation

Effect of Substrate Concentration on Enzyme Activity

1473 words - 6 pages Background An enzyme is a biological catalyst which speeds up biochemical reactions, such as digestion and respiration, but they remained unchanged at the end of the process (Walpole, Merson-Davies, and Dann 53). Problem Question What is the effect of the substrate concentration on enzyme activity? Hypothesis As the concentration of the substrate increases, the rate of reaction also increases until it reaches its maximum point where all

Coursework and practical plan for title "Investigate the effect of temperature on the action of the enzyme diastase on starch."

1003 words - 4 pages For my investigation, I plan to examine the effect temperature has on enzyme action involving the biological catalyst- diastase, and its substrate- starch. In lesson, I have conducted a preliminary experiment to give me an idea of what to expect and a chance to conduct the experiment before hand. From my preliminary work I believe that an equal amount of substrate (Starch) with an equal amount of enzyme (Diastase) should finish reacting at

Biology: Experiment- The Effect of Temperature on the Enzyme Rennin

1890 words - 8 pages Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin.Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC, which is the body temperature, where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the
