What are biological molecules? What are multiple-choice exercises on biological molecules according to grade 10 curriculum in Vietnam?

Concept of biological molecules:

Currently, many students do not know what a biological molecule is. The concept of a biological molecule refers to organic molecules that are aggregated and exist within living cells. Major biological molecules include proteins, lipids, carbohydrates, and nucleic acids.

Biological molecules play a crucial role in biological processes such as cell structure, storing and transmitting genetic information, and providing energy for cell activities.

Students can refer to some multiple-choice questions on biological molecules for Grade 10 below:

Question 1: The four main elements comprising living matter are:

A. C, H, O, N

B. C, H, O, P

C. O, P, C, N

D. H, O, N, P

Question 2: Among approximately 25 elements that constitute life, the elements that make up the majority of living organisms (about 96%) are:

A. Fe, C, H

B. C, N, P, Cl

C. C, N, H, O

D. K, S, Mg, Cu

Question 3: The primary chemical elements that make up living organisms are which elements?

A. C, H, O, N

B. The outer ring of its electron configuration has 4 electrons

C. It is a main element in the chemical composition of substances that make up living organisms

D. It is used as the unit to determine the atomic weight of substances (amu)

Question 11: Most major elements are cumulatively used in
