The answer is water molecules are split. The water split using the energy of light and also form ATP to provide energy for carbon fixation in dark reaction.

The right answer is Water molecules are split.

H2O water is the source of electrons for photosynthesis in plants and cyanobacteria. Two water molecules are oxidized by four successive charge separation reactions in Photosystem II to yield one oxygen molecule O2, four H + protons and four e- electrons. Each of the four electrons transits through a tyrosine residue to P680 which serves as the primary electron donor of the photosystem II reaction center.

Given what we know, we can confirm that the three pathways of photosynthesis (C3, C4, and CAM) are all similar in that they use CO2 as the substrate in order to produce sugar, which is carbon-based.

<h3>Why are these pathways similar?</h3>
  • These pathways all produce carbon-based molecules in the form of sugars or carbohydrates.
  • These pathways are also similar in that they use carbon dioxide as the substrate in order to fuel these reactions and create sugar.
  • Finally, they are also similar in terms of the use of carbon and the production of carbon-based molecules in that they all use the Calvin cycle to complete this process.

Therefore, we can confirm that each of the three pathways of photosynthesis are similar in terms of carbon and the formation of carbon-based molecules in that each of them uses the Calvin cycle in order to turn carbon dioxide into sugars.

What types of structure are most prone to collapse in an earthquake? what types are most resistant to collapse?
Pie

Structures built on land underlain by weak mud that could liquefy are prone to collapse in an earthquake. Also structures built on top of, on, or at the base of steep escarpments could fail and produce landslides.
