This resource includes 19 background questions (to be answered prior to viewing the video Lorenzo’s Oil) and 8 video questions. Through exploring adrenoleukodystrophy (ALD), students will understand how biochemical reactions and cells are interdependent and designed for balance and regulation, and understand how certain cell parts and biochemical components have specific functions. Answers to the background and video questions are now included at the end.

From this concept map and flow chart, students will: summarize the light-dependent and light-independent reactions; state where the light-dependent and light-independent reactions occur; and describe how light energy is converted into chemical energy during photosynthesis. Texts fields are embedded, so students can simply click on the diagrams and type in the appropriate words. Alternatively, they can be printed out for hard copy use.
