- What inferences can be made from the Benedict’s test of the hydrolysates of the following? Was the acid treatment able to hydrolyze the sugars? a. sucroseb. starchc. celluloseIt is quite possible to have a positive reaction in a glucose carbohydrate broth and yet a negative reaction in a glucose use methyl red test. This is due to: O If amino acids are metabolized this will interfere with the methyl red reaction glucose makes acid in a Phenol red test but neutral products in a methyl red test phenol red can detect single acid production but methyl red requires more than one acid produced. methyl red cannot detect the types of acid produced from glucoseSix test-tubes were set up at different pH values. They each contained the same quantity of starch and amylase in water. The table shows the time taken for the reaction to be completed in each test-tube. 1 3 5 7 9 | 11 pH time to be completed/s 95 64 42 35 66 At which pH does the amylase work best? A pH1 pH5 pH7 рH11 O B O A 5
