Detailed explanation-1: -Cardinals use glucose as stored energy. During cellular respiration, they use up the energy inside the glucose to stay active and warm. Carbohydrates are an important part of Northern Cardinal’s diet. Glucose, a simple sugar, is especially important in the winter.
Detailed explanation-2: -(Long chains of structural units are called polymers [poly means many in Greek].) Thus, polysaccharides are high-molecular weight carbohydrate molecules that contain many monosaccharide units.
Detailed explanation-3: -Carbohydrates are also referred to as polysaccharides, and their sugar building blocks are called monosaccharides (mono = 1, poly = many). Choice (a) is incorrect because polypeptides are proteins.
Detailed explanation-4: -Therefore, amino acids are building blocks of proteins and not carbohydrates.
