Structural View of Biology
Structures in the PDB reveal how cells use chemical energy, light energy, electrical energy and mechanical energy to power the processes of life. Cells must continually interconvert different forms of energy. Energy is obtained from many sources, including light and food. Molecular machines then use this energy to build new molecules, to power motion, to transport molecules to the proper place, to generate heat and light, and to regulate all of the processes occurring in the cell. Click on any of the sub-categories below to explore further.
Food is digested and broken down in many controlled chemical steps, capturing chemical energy along the way.
Life on Earth is ultimately powered by sunlight, which is used to build sugars through he process of photosynthesis.
Cells build molecular motors that walk and rotate.
When needed, cells build molecules to create and focus light.
