Fill in the blank In the cyclic pathway, electrons pass through the (a. Ribosomes b. Electron transport chain c. Carbon dioxide molecules)
The energy released from this pumps hydrogen ions into the
( a. Stroma b. Thylakoid compartment c. Chlorophyll) , and these ions power the formation of ATP as they (a. Flow back out of the thylakoid compartment, b. Remain in the thylakoid compartment, c.
Flow back out of the stroma) Sunlight
provides the (a. Energy, b. Gravity, c. Chlorophyll) needed to keep this cycle going.
