It uses energy from atp to alter the conformation of the carrier protein. Large complex molecules are called macromolecules, an example of this is dna. Complex biological molecules are assembled into tiny structures called organelles within which cellular activities are organized. The mitochondrion is an organelle within which the cell extracts energy from food molecules. Membrane- bounded united called cells are the basic unit of life: organismal level: tissue is a group of similar cells that act as a functional unit.
