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).

The gradual change in plants communities of a sand dune ecosystem can be classified as
natita [175]

The types of species in a community gradually change and are replaced through a process known as ecological succession.

<h3>Ecological succession </h3>

The process by which a region's species and habitat mix needs to evolve over time is called ecological succession. These communities gradually replace one another until a "climax community" is reached, such as a mature forest, or until a disturbance, such as a fire, happens. A key idea in ecology seems to be ecological succession.

On the island, ecological succession has produced topsoil that can support ecosystems. As shrub/grassland areas change into forested areas during ecological succession, there are different types of habitat fragmentation.
