LECTURE OBJECTIVES (Instructional goals)1. Give the overall equation for photosynthesis and contrast it to that for cellular respiration, recognize that photosynthesis and cellular respiration are linked in a chemical cycle. (Note that the photosynthesis is the reverse of cellular respiration.)
2. Associate the major parts of photosynthesis with the structure of the chloroplast.
3. Understand that pigments capture wavelengths of light and energize electrons.
4. List the raw materials and products of photosynthesis: know the steps of the Light Dependent and Light Independent reactions, know the raw material needed to start each phase and know the products made by each phase.
5. Explain how autotrophs use the intermediates as well as the products of photosynthesis in their own metabolism.
6. Define selected key terms.
LECTURE QUIZ
