Final answer:
Major elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur are foundational for the molecular components that construct living organisms. They are involved in the formation of nucleic acids, proteins, carbohydrates, and lipids, all vital to cellular and organismal structure.
Step-by-step explanation:
The elements carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), and sulfur (S) are considered major elements that make up the human body. These elements are found in high quantities and are the key building blocks of the chemicals found in living organisms. They are fundamental in forming the nucleic acids, proteins, carbohydrates, and lipids that are the molecular components of life. For example, hydrogen and oxygen form water (H2O), which is critical for various biological processes. The unique interactions between these atoms result in the formation of complex molecules necessary for cells and organismal structures, hence understanding them is crucial for biologists studying life.
