Which term refers to a functional grouping of biomolecules?

The term that refers to a functional grouping of biomolecules is organelle. Organelles are specialized structures within a cell that perform specific functions. They are composed of various biomolecules, such as proteins, lipids, carbohydrates, and nucleic acids, which work together to carry out vital processes necessary for the cell's life and function.

For example, mitochondria are organelles that convert energy from nutrients into usable forms for the cell, emphasizing how a defined grouping of biomolecules can collectively contribute to a specific function. Other examples of organelles include the nucleus, where genetic material is housed, and the endoplasmic reticulum, which is involved in protein and lipid synthesis.

Understanding organelles as functional groups of biomolecules helps clarify how cellular processes are organized and how various components interact to maintain life.
