Question

what does light do when it strikes the chlorophyll molecules of photosystems ii? a. light causes glucose to be synthesized directly inside the chlorophyll molecules of the photosystems. b. light causes the conversion of water into carbon dioxide, oxygen and electrons. c. light directly causes carbon dioxide to attach to rubp during the carbon fixation stage of the calvin cycle. d. light causes electrons to get excited (gain energy) and travel down an electron transport chain embedded in the thylakoid membrane. you are using the free version of this game (with ads). if you want to use the ad - free member version, click the button below. please note: this will open in a new tab/window! please save your progress

Explanation:

In photosystem II, when light strikes chlorophyll molecules, it excites electrons. These excited electrons then travel down an electron - transport chain in the thylakoid membrane. Glucose is not synthesized directly in chlorophyll molecules by light (A is wrong). Water is split into oxygen and electrons in the light - dependent reactions, not converted into carbon dioxide (B is wrong). Carbon dioxide attachment to RuBP in the Calvin cycle is not directly caused by light (C is wrong).

Answer:

D. Light causes electrons to get excited (gain energy) and travel down an electron transport chain embedded in the thylakoid membrane.
