The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate. Study with Quizlet and memorize flashcards containing terms like Step 1-Light Dependent, Step 2- Light Dependent, Step 3- Light Dependent and more.
Step 1. Click the card to flip 👆. The light dependent reactions begin in photo system II. This photo system is called photosystem II simply because it was discovered after photosystem I. Chlorophyll molecules in photosystem II absorb light. This absorption of light raises electrons in chlorophyll to a higher energy level. Click the card to flip 👆.

5 days ago · 1.) Photon of light hits a pigment in LHC of PS1. This excites the electron to move away from the nucleus to increase energy level. 2.)Electron returns to grand state (original place) and energy is lost) 3.)Energy lost excites the next pigment in LHC, this excites electron to move away from nucleus to higher energy level, returns to ground ...
