Question

1. Photosynthesis and cellular respiration are necessary processes for ecosystems. Interestingly, when comparing these two processes we find that they have some aspects that are similar with each other and other aspects that exhibit complimentary or mirror-image symmetry. Using the table below, answer the questions about the two processes in the photosynthesis and respiration cells to the right. Answer only in the space provided Photosynthesis Cellular Respiration Write the chemical equation for the process a) What is the name of the cyclic stage? b) Where does it take place (be specific)? a) What is the name of the stage that releases the energy of electrons in a controlled fashion? b) Where does it take place (be specific)? Considering the two stages identified in the two boxes above, which one occurs first? What is the name of the process used for ATP synthesis? What enzyme is used for ATIP synthesis? Where is this enzyme (above) located? (be specific) Explain the importance of compartmentalization for the processes

Explanation / Answer

Photosynthesis
1. 6CO2 + 6H2O + light energy = C6H12O6 + 6O2.
2. Calvin cycle and stroma
3. Photophosphorylation. Thylakoid membrane
4. Photophosphorylation occurs first
5. noncyclic photophosphorylation.
6. ATP synthase
7. Thylakoid membrane
8. Comparmentalize makes the different process occurs by any interference.

Cellular respiration
1. C6H12O6 + 6O2 --> 6H2O + 6CO2 + ATP.
2. TCA cycle and Mitochpndria matrix
3. Oxidative phosphorylation. Mitochondria inter membrane
4. TCA cycle occurs first
5. Chemoisomosis
6. ATP synthase
7. Mitochondria inner membrane
8. Comparmentalize makes the different process occurs by any interference.
