Cellular Respiration: Harnessing Energy using Biological Macromolecules


a.    Glucose, a carbohydrate, is one of the main starting products in cellular respiration. 

                                              i.    What other monosaccharides can be converted to glucose?



                                             ii.    In what phase of cellular respiration is glucose used?



                                            iii.    Can non-carbohydrate molecules such as amino acids be used to make glucose?



2.    Lipid Metabolism:

a.      Lipids are also a source of energy, particularly triglycerides.


                                              i.    Name the parts of a triglyceride molecule.



                                             ii.    Name the part of the triglyceride that can be used for cellular respiration molecule.


                                            iii.    What organelle converts the triglyceride part to the cellular respiration molecule? (Hint: mentioned in the Cytology Lab)



                                            iv.    In what phase of cellular respiration is this molecule used?


3.    Protein Metabolism:

a.    As a last resort, like in cases of starvation, proteins can be used as energy.

                                              i.    What is the monomer for proteins?



                                             ii.    How can the monomer for proteins be used in cellular respiration? Include how it must be processed before being used.




                                            iii.    After processing, the remainder of the monomer can be used in the first three phases of cellular respiration. List the first three phases of cellular respiration.



4.    In an effort to combine the information, answer the following essay question:

a.    How are biological macromolecules used as an energy source for cellular respiration?
