What organic molecule is most important as the source of building blocks for cell structure and least important it’s role as an energy source

Proteins

Explanation:

Proteins are organic molecules made from chains of around 20 amino acids. They are fundamental for the structure and functioning of cells. For example, they are crucial for the composition of the cell membrane and also control most of the activities of the cell such as mitosis and meiosis.

Proteins are the most important structural component of cells. However, their role as an energy source is not as important as carbohydrates, another organic molecule, which are extremely important for their roles as the energy source of the cell.
