Consider the following reaction:     4 Fe + 3 O2 → 2 Fe2O3 If [x] grams of iron react with an excess of oxygen gas, what mass, in grams, of Fe2O3 can form? (Fe2O3 = 159.70 g/mol)

If the reaction below produces [x] kJ of energy, how many grams of KCl will be produced? (KCl = 74.55 g/mol)      2 K (s) + Cl2 (g) → 2 KCl (g)          ΔHrxn = –873.0 kJ

What is the access modifier that allows a class or method to be accessed from anywhere in the same package, but not from outside the package?

A subclass may re-write the code of an inherited method, then the method is:

Individual Problem 2_Meditech Pharmaceuticals.docx

Porphyrin rings, such as are found in heme, are the basis for molecules that are involved in critical metabolic processes (eg., glycolysis).  What are two porphyrin ring-based compounds that are essential to metabolism?

In addition to glycolysis, we learned about two (2) alternative pathways of glucose metabolism. a.  What are the names of these two (2) alternative pathways? (2 points) b.  Which pathway is used only by prokaryotes?  (1 point) c.  Why would a cell want to use either of these alternative pathways instead of using glycolysis?  (1 point)

              are the three-letter “words” that are translated into amino acids by            .

Put the steps of protein catabolism in the correct order:  I – deamination; II – two-carbon molecules enter the Krebs cycle; III – digestion with extracellular proteases; IV – transport of the amino acids into the cell via membrane channels.
