Q3.
typically, according to kinetics, the more enzymes will have the more active sites , therefore, the rate of reaction should increase proportionally.
The increase of amylase, an enzyme, should increase the rate of reaction
Q4
positive test for glucose in benedicts reagent will be -->
the blue solution (benedict reagent) should form a very orangE/redish color if any sugar is present
Q5
starch in iodine will give a black/dark coloured compound, which is Iodine trapped inside the starch

1) Based on the explanation on the interaction between starch, salivary amylase and iodine solution at the beginning of the presentation, please give a brief explanation on the differences in colour over time for each concentration. 2) Why do you think the rate of reaction increases as the concentration of the enzyme is increased? Is the rate of reaction increasing indefinitely as the concentration increases? 3) Why do you think the reaction rate is different as the pH of the...

1. Show the chemical reaction that takes place when Benedict's reagent (Cu") reacts with glucose (use open chain Fisher projection). 2. Do you expect fructose to give a positive reaction with Barfoed's reagent? Explain why or why not. Indicate which of the test carbohydrates (glucose, fructose, lactose, sucrose, starch) would give 5- hydroxymethylfurfural when heated with hydrochloric acid. (See description of reactions for Barfoed's reagent and Seliwanoffs reagent). 3. 121

Question 3 A Amylase is a protein that catalyzes the conversion of starch to simple sugars. Amylase activity in an aqueous solution can be measured by using iodine as a starch indicator. A solution containing iodine and starch will have a dark blue color, whereas a solution containing iodine but no starch will have a light brown color. The color change of an iodine solution from dark blue to light brown can be used to measure the rate at which...

the rate of a certain enzymatic reaction is 2.18 micromol dm^-3 s^-1 when the overall concentration of enzyme is 3.96mmol dm^-3 and the concentration of substance is 0.0400 mol dm^-3. When the substrate concentration is increased to 0.100 mol dm ^-3 and the enzyme concentration is unchanged, the rate increase to 3.97 micromol dm ^-3 s^-1. Find the Michaelis constant and the maximum velocity for this enzymatic reaction.

Part 1: Characterization of carbohydrates with and without digestion by enzymes (You can refer to the complete Lab Procedure which is posted separately for more information about this part of the lab.) You are given a set of samples: starch, sucrose, and glucose. The samples are tested before and after different enzymes are added. After the enzymes are added, the samples are incubated in a 37°C water bath...
