Reality Check -- The ten questions below do not cover everything you need to know in order to understand the next chapter. However, if you DO know the answers to the questions you are well underway and are ready to start learning about the Cellular Respiration.

1. Molecular formula of glucose?


2. Reaction formula of photosynthesis?


3. Reaction formula of cellular respiration?


4. Macromolecule group of enzymes?


5. Give the building blocks of

a. Polysaccharides
b. Fats
c. Proteins
d. Nucleic acids



6. pH of a strong acid?


7. Name the two sub-reactions of the photosynthesis.


8. Give the

a. REACTANTS of the 1st subreaction of the photosynthesis.
b. PRODUCTS of the 1st subreaction of the photosynthesis.
c. REACTANTS of the 2nd subreaction of the photosynthesis.
d. PRODUCTS of the 2nd subreaction of the photosynthesis.


9. The photosynthesis requires input of energy (light) and is a non-spontaneous reaction. The cellular respiration is a spontaneous reaction and do not require energy input, other than a small amount of activation energy. Is the photosynthesis an endergonic or exergonic reaction? Is the cellular respiration an endergonic or exergonic reaction? (Hint: endo means "in", exo means "out".


10. Give the building blocks of

a. Enzymes
b. Starch
c. Hemoglobin
d. Glycogen




How did you do on the reality check?

If you don't know the answers to these very basic questions, you are going to have a hard time understanding the material covered the next few lectures. I strongly recommend that you review the chapters given as the "answer" above.
