Question

The two richest known sources of edible proteins are
(a)Meat and eggs
(b)Some algae and other microorganisms
(c)Soyabean and groundnut
(d)Milk and leafy vegetables

Answer 1

Hint: Proteins are polymers of amino acids that are very essential for the proper functioning of our body. One of the richest sources of edible proteins also has high amounts of the estrogen-like chemicals in it.

Complete answer:
Soybean has soy protein in it which is a “complete protein” as it has all the essential amino acids required by our body. Essential amino acids are the acids that are not produced by our body and have to be taken from outside. This is the reason why it is always told to vegetarians to eat soybeans to fulfill their amino acids intake.
Groundnuts are also known as peanuts which is a type of legume. It is considered one of the best sources of proteins. It also consists of vitamin E, magnesium, copper, and arginine thus, providing all-around good nutrition. They are also very rich in energy as 100 gms of peanuts contain 600 calories.

Additional Information: Let us study some more sources of protein:
Meat, Eggs, and Milk: All are sources of complete proteins. They help produce lean muscles in our bodies quickly.
Algae, Bacteria, and Fungi: These organisms are now used as Single Cell Proteins SCP because of their high protein value. They produce more amounts of protein much faster than conventional methods.
Leafy vegetables: Amongst all the leafy vegetables, spinach is considered the best source of proteins as 100 g contains 3 g protein.
So, the correct option is ‘Soyabean and groundnut’.

Note: -The deficiency of protein in infants of one year old or more causes a disease known as Kwashiorkor.
-Symptoms of this disease include poor growth and mental development, swelling and edema, and thinning of limbs.
-In order to avoid such diseases, biofortification is used. It is a method by which crops are bred with higher levels of proteins, minerals, and amino acids.
