Polysaccharide digestion and glycogen breakdown involve sequential cleavage from ends of glucose polymers. a. ionic b. non-reducing c. hydroxyl d. reducing

non-reducing

Explanation:

The end of a polysaccharide where anomeric carbon is involved in the glycosidic linkage is called a non-reducing end. Digestion of polysaccharides and glycogenolysis includes the removal of sugar residues one by one from the non-reducing end.

For instance, glycogenolysis in skeletal muscle and liver includes many enzymes. One such enzyme is glycogen phosphorylase that catalyzes the sequential breaking of alpha 1->4 glycosidic linkage between two glucose residues at a non-reducing end of glycogen. It removes the terminal glucose residue as alpha-D-glucose 1-phosphate.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
