Answer:

1. ATP - decrease

2.NADPH - decrease

3. sugars - decrease

Explanation:

Photosynthesis is a type of biosynthesis that produces glucose from the reactants: sunlight, carbon dioxide, and water. It occurs in the chloroplast in two phases, the light-dependent, and light-independent/dark reactions where sugars are made. Pigments like chlorophyll absorb light energy at specific wavelengths in the light reaction which activates photosystems

Here:

  • chlorophyll forms photosystems (PS I & PSII) with proteins called a complex
  • PS II absorbs and transfers light energy to the reaction core.
  • a water molecule is split apart to form an electron, H+ and oxygen
  • Electrons are shifted to photosystem I from photosystem II.  
  • ATP and inorganic phosphate are synthesized from ADP.  
  • H+ is added to NADP to form NADPH

The NADPH is integral to the Calvin Cycle, as part of the light independent reactions- these synthesize sugar molecules.

If PS II no longer works,  there will be less ATP, NADPH, and no sugars produced.

What would happen to the concentrations of ATP, NADPH and Sugars if Photosystem II (PSII) stopped working is a: decrease.

During photosynthesis, the primary acceptor of carbon are Photosystem I (PSI) and Photosystem II (PSII) because it occurs in a light-dependent reaction.

Photosystem II (P680) is a large membrane protein complex which serves as a primary acceptor of carbon during a light-dependent reaction.

However, the following would happen when the Photosystem II (P680) stops working:

  • A decrease in the concentrations of ATP.
  • A decrease in the concentrations of NADPH.
  • A decrease in the concentrations of Sugars.
