Use this coloring worksheet to explore how plant cells harvest energy form the sun to generate ATP in the process known as chemiosmosis.   This diagram showcases the enzymes and steps of photosystem I and photosystem II. Explore how these systems create a concentration gradient which powers the production of  ATP through the ATP synthase compound.

Chemiosmosis is a biological process that involves the movement of ions, usually protons (H+), across a biological membrane, creating an electrochemical gradient that can be used to drive ATP synthesis. First, Ions move across a semi-permeable membrane, such as the membrane inside mitochondria, by diffusion. The movement of ions generates an electrochemical gradient that can be used to drive ATP synthesis

Worksheet includes a description of the processes and requires students to answer specific questions about the light independent and light dependent reactions.  Students must color the diagram according to the directions.
