Cellular processes require a steady supply of energy. From where, and in what form, does this energy come? How do living cells obtain energy, and how do they use it? This tutorial discusses different forms of energy and the physical laws that govern energy transfer. This tutorial also describes how cells use energy and replenish it, and how chemical reactions in the cell are performed with great efficiency.
