Homework Answers
Answer: (C) Hydrolysis. ( It is process of breaking down of the water molecule into a small particle it is same as the digestion of food where large molecules break down into smaller ones.)
Answer: True ( In the hydrolysis reaction ( break down of ATP) energy is required)
Answer: The example of disaccharides is Sucrose, the sugar from sugar cane and sugar beets (sucrose) is made from glucose and fructose.
Answer: Glycogen ( Polysaccharides are long chains of monosaccharides which is linked by glycosidic bonds)
Answer: Starch (Starch is used in the plant for the energy storage)
