Proteins, the essential biochemical foundation of the cell, fulfill a variety of tasks within the human body. This program provides insights into their structure and several of their functions, including their role in catalytic biochemical reaction and reproduction. How proteins recognize the "packaging" of smaller molecules is explored. Using a photosynthetic protein—a proton pump—as an example, excellent computer simulation shows the proteins at work, moving an atom through the system. (37 minutes)
