Question

Most common protein and carbohydrates found in cow’s milk are
(a)Albumin, lactose
(b)Globulin, casein
(c)Casein, lactose
(d)Casein, fructose

Answer 1

Hint: Proteins are biomolecules which consist of more than one change of amino acid and are polymers which occur naturally. Carbohydrate is a biomolecule which consists of monomers of monosaccharides and is known as simple sugars. The most common protein is one that makes the milk a colloidal solution while the carbohydrate gives milk the fat content.

Complete answer:
The most common protein and carbohydrates found in cow's milk are Casein and lactose. In the cow, the latter's get synthesized in the mammary gland and the sugar circulates in the blood. Glucose provides the energy that is required for milk synthesis as cows produce 50 kg of milk in which 2.5 kg of lactose is required to synthesize and is essential for the manufacture of milk fat. 72 grams of glucose produces 1 kg of milk which is required by the mammary gland. Carbohydrates get fermented by rumen microbes in the ruminants. Casein in the cow is the major component for protein and is important for its nutritional value. It contains large colloidal micelles which give milk its particular functional characteristics.

Additional Information: Starch is the primary energy source for a cow which is derived from cereal silages and grains. The intake and method of processing depends on the starch consumed which can be degraded in the rumen. Starch degradation involves some steps in which the first step is the starch degradation. It involves the cleavage of change into some glucose units and products which are mainly volatile fatty acids including butyric, acetic, lactic, and propionic acid. The bloodstream absorbs the vital fatty acids which carry the product of digestion to the liver and the lactic and propionic acid gets converted into glucose. Amino acids get digested in the small intestine from proteins where they provide much of the remainder. Glucose gets breakdown in the rumen and for the recent thesis takes place in the liver where it is inefficient. The amount of glucose present in the portal blood is limited and it is released by the digestion which is transported into the cells lining the small intestine.
So, the correct answer is 'Casein, lactose'.

Note: All cows are females and the male is known as bulls and they consist of the complicated digestive system. They spend 10 to 12 hours of the day lying and their average sleep time is about 4 hours a day. The day consists of about 300 degrees of vision with a blind-spot and is good for swimmers.
