Final answer:
The dehydration synthesis process likely occurs after photosynthesis, not cellular respiration, as it utilizes the glucose produced during photosynthesis to form complex carbohydrates through the removal of water molecules.
Step-by-step explanation:
The dehydration synthesis process would be most likely to happen after photosynthesis. During photosynthesis, glucose is produced, which can then be used in dehydration synthesis to form more complex carbohydrates such as starch and cellulose. This process involves removing water molecules to bind smaller units together.
This carbohydrate synthesis is part of the cellular metabolism that occurs after the energy from the sun is captured and converted into chemical energy in the form of glucose during photosynthesis.
In contrast, cellular respiration breaks down glucose to produce ATP, the energy currency of the cell, which is the opposite of biosynthesis pathways like dehydration synthesis.
Therefore, it is logical to conclude that the dehydration synthesis mentioned in model 4 would follow the photosynthetic process rather than cellular respiration, as the energy and base molecules needed for dehydration synthesis are outcomes of photosynthesis.
