Important Biomolecules NEET Questions 

A lot of people asked me to provide MCQs on Biomolecules .

In this we have use to quiz of some MCQ on Biomolecules.

Before reading this i suggest you to read the post first and then attempt test. 

Biomolecules is a chapter of class 11 NCERT Biology as well as Chemistry class 12 NCERT textbook., which is considered a very important chapter as per the NEET competition.

Biomolecules is important chapeter for study in Biology, especially in Class 11th Biology NCERT textbook.

Besides this, you will get also it to study in Organic Chemistry in Chemistry class 12Chemistry textbook.

If seen from the NEET exam perspective, it is an important chapter and 3 to 5 questions are commonly asked from this chapter in zoology and botany sections of NEET exams every year.

As we know that, some chapters have been removed on as per the new education policy (NEP-National Education Policy 2020), so if seen then it is possible that in the coming years, multiple choice questions from this chapter will increase.

The number of Biomolecules MCQ can be more.

It is important to note that Biomolecules chapter is completely conceptual and only if you have basic knowledge of Chemistry, then you will be eaisly able to understand this chapter properly.

Thus keep in mind that here you will not only learn to biology,  we also have to study chemistry along with biology, which we called biochemistry.

Hope you will enjoy during attempt of the given multiple choice questions on your own but still if you see any mistake or any updates then you can comment or mail.

Have a nice online Journey

Thank you
