Exam 3 Review Sheet
Chemistry 1120

Dr. Doug Harris
•
Review the three main stages of metabolism for proteins, polysaccharides,
and lipids.
•
Understand the meaning of the terms metabolic, catabolic, and anabolic
reactions.
•
•
Review how the hydrolysis of ATP can be used to “drive” another reaction.
•
Review the vitamins necessary to create the coenzymes NAD, FAD, and
Co-A. Review the oxidized and reduced forms of NAD and FAD. Review
the general reaction characteristics that involve NAD and FAD (ie. C-C
forms C=C with the help of FAD). Review what is added/removed to/from
each of the coenzymes during their respective reactions.
•
Review Figure 23.8. Be able to predict reactants and/or products in
reactions as we did in class.
•
Know reactants, products, coenzymes, and enzyme names for all of the
glycolytic reactions. Know structures of reactants and products. Review
how much energy is used and produced in glycolysis.
•
Review the pyruvate pathways in the presence or absence of oxygen
(Figure 23.11).
•
•
Review glycogenesis (Figure 23.12) Know the reactions involved.
•
Review Figure 23.14. Understand which gluconeogenesis enzymes are
different from the glycolytic enzymes.
•
Know reactants, products, coenzymes, and enzyme names for all of the
citric acid cycle reactions. Know structures of reactants and products.
Review how much energy is produced in the citric acid cycle once it is
coupled with the electron transport chain.
•
Review the four electron carriers that we discussed in class (FMN, ironsulfur clusters, coenzyme Q, and heme). Review the oxidized and reduced
forms of these carriers in general terms (FMN oxidized, FMNH2 reduced).
Be able to fill in blank spaces in a redox reaction with respect to these
carriers as we did in class.
Be able to write an overall equation describing a coupled reaction with the
hydrolysis or formation of ATP (as we did in class).
Review the figure on page 775 that describes glycogenolysis and
glycogenesis. Understand how the described hormones of the figure can
effect these reactions.
•
Review complexes and electron carriers of the electron transport chain
(Figure 24.9). Be able to complete electron transport reactions (problem
24.33) as we did in class.
•
Review Figure 24.10. Be able to trace the flow of electrons from NADH or
FADH2 all the way to water. Understand how ATP synthase creates ATP
and what is the driving force behind creating ATP. Know the different parts
of ATP synthase.
•
Be able to account for all ATP lost and created in glycolysis, the citric acid
cycle, and the electron transport chain.
•
•
Review how the glycerol backbone of triacylglycerides is metabolized.
•
Be able to account for all ATP produced in the beta oxidation of a
specified fatty acid.
•
Review what ketone bodies are and under what conditions they are
created.
•
Know reactants, products, and coenzymes for all of the fatty acid
synthesis reactions. Know structures of reactants and products.
•
Review Figure 25.7 and the digestion of proteins. Know the enzymes and
their locations that are involved in protein digestion.
•
Review transamination and oxidative deamination reactions. Be able to
predict the products formed from transamination reactions as we did in
class.
•
•
•
Review the structure of urea and the purpose behind the urea cycle.
Know reactants, products, coenzymes, and enzyme names for all of the
fatty acid beta oxidation reactions. Know structures of reactants and
products. Review how much energy is produced in the beta oxidation of
fatty acids.
Review the terms of gluconeogenic and ketogenic amino acids.
Review the reactions of forming glutamine from glutamate, aspartate from
oxaloacetate, and alanine from pyruvate. Be able to predict reactants or
products for the previously mentioned three amino acid synthetic
reactions.
