1. Write the overall equation for the BALANCED aerobic cellular respiration reaction. Write the chemical (molecular) formulas AND names of the molecules. Label the reaction as endergonic or exergonic. Label products and reactants and state in which process(es) each product or reactant comes into play (Glycolysis, Krebs, ETC)
2. Write the overall equation for the BALANCED photosynthesis reaction. Write the chemical formulas AND names of the molecules. Label the reaction as endergonic or exergonic. Label products and reactants and state in which process(es) each product or reactant comes into play (light reactions, Calvin cycle).
3. Explain how the products and reactants of cellular respiration are related to the products and reactants of photosynthesis. Be specific. Explain why plants must do both reactions and people do not.
4. Why is cellular respiration essential to life?
5. Why is photosynthesis essential to ALL life â not just plant life? Think of two big reasons!
6. How is photophosphorylation (not photosynthesis) similar and different than oxidative phosphorylation? Write a compare and contrast answer. You must have at least 2 similarities and 2 differences. This must be written as a paragraph and not a list. When you state a difference for one, give how the other is different too!
7. An electron transport chain (ETC) chain is essential for cellular respiration. What is the function of the ETC in cellular respiration? Draw a diagram illustrating the ETC in cellular respiration.
8. An ETC chain connects PSII and PSI. What is the function of electron flow from PSII to PSI? Draw the Z-scheme illustrating the ETC in photosynthesis.
9. The inner membrane of a mitochondrion has lots of folds, or cristae, giving it lots of surface area for electron transport chains. Suppose the inner membrane was smooth instead, how would this affect cellular respiration?
10. The chloroplast has a couple of different spaces â the lumen of the thylakoid and the stroma. Explain why it is essential to have these spaces separated by membranes.

The Major Metabolic Processes of Eukaryotic Cells
Plants are classified into a unique Kingdom based on the fact that they are able to make their own food. Some of this food is stored for later use but some of it is used immediately for various metabolic processes that require energy in the form of ATP. Considering this, imagine the inside of a plant cell where both anabolic Photosynthesis and catabolic Aerobic Cellular Respiration are occurring. In order for this plant cell to stay alive it must stay in a constant state of disequilibrium. This requires that the product of one reaction does not accumulate but becomes the reactant in the next step. Fill in the following chart that organizes the major events of these metabolic processes keeping in mind how each event leads into the next.
Metabolic Process | Event | Organelle the Event takes place within | Specific Location within Organelle (Event takes place within) | Input (Reactants) | Output (Products) | Enzyme(s) Involved (may be more than 1!) | Goal of Event [product(s) that get produced & why] |
