What kind of reaction adds water to break large biomolecule

________ What kind of reaction adds water to break large biomolecules into subunits? ________ What kind of protein is lactase, the biomolecule that speeds up the breakdown of lactose? ________ What kind of bond forms during a dehydration synthesis reaction involving two amino acids? ________ If maltose undergoes hydrolysis, what subunits result? ________ As what molecule do plants store glucose? ________ If starch is present, what color will the iodine turn? ________ If a solution contains a large amount of glucose, what color will the Benedict\'s reagent become?

Solution

1. Hydrolysis reaction- water molecule breaks down into OH- and H-

2. Lactase is a protein made of long chain of amino acids and at the same time it is an enzyme which helps in chemical reactions

3. Covalent bond- between oxygen from first amino acid and hydrogen from second amino acid to produce a peptide.

4. Glucose subunit- maltose is a disaccharide formed from glucose molecules

5. Starch- a polysaccharide

6. Blue black colour if starch is present. Starch changes the arrangement of amylose coils and causes the visible light absorbable

7. Clear blue colour- due to sodium and copper salt
