Cyclic Electron Flow

Only uses what

Photosystem 1

Purpose to make

ATP

How many steps are there

four

1. Light what by what, an what is what by 700nm

Light CAPTURED by PHOTOSYSTEM 1, an ELECTRON is EXCITED by 700nm

2. Chlorophyll is what and the what moves down the what within the what

Chlorophyll is OXIDIZED and the ELECTRON moves down the ETC within the THYLAKOID MEMBRANE

3. With each what along the what, the electron loses what and the what harnessed produces what

With each REDOX REACTION along the CHAIN, the electron loses POTENTIAL ENERGY and the ENERGY harnessed produces ATP

ADP + Pi + ENERGY → ATP

4. The what eventually returns to what in the what again

The ELECTRON eventually returns to GROUND STATE in the PHOTOSYSTEM 1 again
