The middle layer of a kernel of grain that contains carbohydrates and proteins is the
A
bran
B
endosperm
C
hull
D
germ
Explanation: 

Detailed explanation-1: -The endosperm is the interior layer that holds carbohydrates, protein, and small amounts of some B vitamins and minerals. These components have various effects on our bodies: Bran and fiber slow the breakdown of starch into glucose-thus maintaining a steady blood sugar rather than causing sharp spikes.

Detailed explanation-2: -The endosperm is the germ’s food supply, which provides essential energy to the young plant so it can send roots down for water and nutrients, and send sprouts up for sunlight’s photosynthesizing power. The endosperm is by far the largest portion of the kernel.

Detailed explanation-3: -There are three parts of a wheat kernel: the bran, endosperm and germ. The bran is the outer shell of the grain and is high in fiber and B vitamin. Inside the bran is the endosperm, which makes up most of the kernel and mainly contains starch.

Detailed explanation-4: -The endosperm contains the greatest share of protein, carbohydrates, and iron, as well as B-vitamins such as riboflavin, niacin. It is also a source of soluble fiber. Bran is about 14% of the kernel weight.

Detailed explanation-5: -The endosperm is a part of the female gametophyte that is very bulky and stores the nutrients to provide nutrition to the developing embryo. The fruit wall appears thin and gets fused with the seed coat.
