These massive molecules are often very specific in function, and under poor conditions can rearrange themselves in such a way that they no longer work. Organelles include mitochondria, which are responsible for the energy transactions necessary for cell survival; lysosomes, which digest unwanted materials within the cell; and the endoplasmic reticulum and the Golgi apparatus, which play important roles in the internal organization of the cell by synthesizing selected molecules and then processing, sorting, and directing them to their proper locations. But now let's go to the next scale up. He suggests that a cell nucleus will be larger than an atomic nucleus, because a cell is larger than an atom. Size: Atoms are smaller than cells. A high-yielding, strictly regioselective prebiotic purine nucleoside formation pathway. This is actually a comparison this side by side. The overall process of cellular reproduction occurs in two steps: cell growth and cell division. An average-sized protein macromolecule contains a string of about 400 amino acid molecules. Chemistry.
