Kemtec Science: Photosynthesis II - Synthesis of Starch

• Target Grades: 9-14
• Number of Students: 24 students working in six groups of four.

Photosynthesis II examines the phosphorylation of glucose to produce starch in plant cells. Students collect phosphorylase in potato extract and use it to catalyze the synthesis of starch. They learn that starch synthesis requires primer starch to which glucose residues can be added and that inorganic phosphate inhibits starch synthesis.
