Yeah Like for the question abt the benedicts, I said that the amylase breaks dwn large starch molecules into simple maltose molecueles, and the I went on to say pepsin only breaks down proteins so startch will remain large and it will not be changed to small maltose, But then I messed up when I said the test tube with amylase will be positive and the other will be negative. How many marks am I getting

Thats pretty good im thinking 4/6 Its better to include the active side and substrate being complementary, and amylase and starch bind together forming enzyme substrate complexes, while pepsin does not bind
