What would happen to the concentrations of ATP, NADPH and Sugars if PSII stopped working?
dezoksy [38]

Answer:

<u>1. ATP - decrease </u>

<u>2.NADPH - decrease </u>

<u>3. sugars - decrease </u>

And    <u>True- Both ATP and NADPH are needed to make sugars.</u>

Explanation:

Photosynthesis is a form of biosynthesis that produces glucose from the reactants;  it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.

Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII).  PS II absorbs and moves the reaction center with light energy.  

  • H+, and oxygen,  are formed from a water molecule as it's broken apart.
  • From photosystem II, electrons are transferred to photosystem I.  
  • ATP is synthesized from ADP along with inorganic phosphate.  
  • To form NADPHH, H+ is added to NADP

If PS II no longer works,  there will be less ATP, NADPH, (both used later on) and no sugars produced.

In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of <u>CO2 with Ribulose 1,5-bisphosphate </u>(RuBP).

What is the difference between the floodplain, meander, delta, and what ecosystem services do each provide?
natima [27]
<span>These are some distinguished areas in ecosystems that help the humans immensely. Floodplain is area that lies low and is subjected to floods in regular periods making it reduce intensity of floods and improving the stability of the soil. This also improves water quality and ground water making the ecosystem suitable for flora and fauna. Meander unlike floodplain is a broad valley like which is with time develops with bends and helps the ecosystem by reducing the speed of river flow. Delta is the region that is formed around the vast water bodies because of the water flow or the lack of it. It helps the ecosystem by giving protection from natural calamities like floods and hurricanes.</span>
