In this way, catalysts use the small molecules brought into the cell from the outside environment to create increasingly complex reaction products. However, the actual radius of hydrogen molecule is 120 pm which is greater than that of hydrogen atom i.e. dramatically up in size and dramatically up in complexity. And a red blood cell is going to be six to eight micrometers, micrometers wide. This is actually a comparison this side by side. No, a cell is not bigger than a molecule. A chromosome is made up of genetic material (one long piece of DNA) wrapped around structural support proteins (histones). Or five billionths of a meter. Before fertilization, the entire interior of the egg consists of a single cell, which can weigh up to 5 pounds. A chromosome contains many genes. Carbohydrates are organic compounds made of C, H, and O atoms.

Bert's thinking here is quite reasonable, within the limits of his knowledge. The nucleotide is a large molecule, with several different varieties, but will always contain more atoms than glucose, a simple sugar. In addition to mass, we can also measure how big a molecule is. By . Additionally, molecules are not able to divide while cells can constantly divide. Cells are the building blocks of our bodies, and molecules are the components that allow for chemical reactions to occur. Examples would be carrier-mediated pumping of molecules in or out of the cells, group translocation in which some action coverts a molecule as it is being transported inside the cell, and bulk transport to bring in larger molecules by engulfment. A human cell averages around 100 m A water molecule is about 0.000282 m. Examples are starch, glycogen, and cellulose. However, all cells share strong similarities in biochemical function.
