MIT Biology Hypertextbook: Chemistry Review
... a review of important chemical interactions and concepts you will encounter in this course. 1 Chemical Bonds This section provides a quick review of chemical bonds. Emphasis is placed on bonds between the six major elements found in biological systems: H, C, N, O, P, and S. 1.1 Covalent Bonds Covalent Bonds are the strongest chemical bonds ...

... first is the photochemical capture of light energy and its temporary storage in high energy chemical bonds. (The chlorophyll experiment exposed students to this first step in photosynthesis.) The second stage _ ... of discussion in this experiment _ uses the energy temporarily stored in the high energy bonds of ATP and NADPH to accumulate organic compounds in the plant. This is a complete ...
