Cells are the basic unit of life and can range in size from a few micrometers to several hundred micrometers in diameter. Mostly, ribosomes are not bound by membrane but they can become membrane bound during the protein synthesis. The comparison between cells and molecules in terms of size is not accurate because a cell can only be measured in terms of micrometers and a molecule in terms of nanometers. Enzymes act as catalysts by binding to ingested molecules and regulating the rate at which they are chemically altered. Neurons are connected to their target cells via synapses.
