Compare and contrast glycogen with starch with respect to the following: a. Monomer of each b. Name of the covalent bond that joins the momomers in these molecules c. Branched or unbranched structures d. synthesized by plant or animal 

Speculate the type of fatty acid composition in the cell membranes of bacteria grown at 4’C than the membranes of bacteria that are grown at 37’C. Also, include the role of cholesterol in membrane structure.  Give reason for your answer. 

Determine if glycolysis will proceed in a cell that has been provided with glucose, ADP, NAD+, and water. Give reason for your answer.

______________ functions to carry electrons in oxidative phosphorylation from the first enzyme complex to the second enzyme complex.  

Glycolysis involves producing energy from carbohydrates. Often times, our foods don’t have just glucose, but other sugars such as fructose (in table sugar) and galactose (in milk). Let’s consider fructose.   Assuming fructose can be phosphorylated by hexokinase, in which step of glycolysis would fructose enter? What will be the reaction and the name of the enzyme that catalyzes this reaction.

NADH and NADPH are 

An enzyme inhibitor called as diisopropylflourophosphate (DFP) covalently binds to a serine amino acid in the active site of a serine protease, thus inactivating the enzyme.  Based on this information, what type of enzyme inhibitor is DFP? Give reason for your answer.

An athlete has an inactive glycogen phosphorylase enzyme.  Determine what will be the consequences of this defective enzyme. Include in your answer the role of this enzyme and it’s limitations. 

These are not the examples of diastereoisomers that are also epimers because they differ in stereochemistry at multiple  chiral carbon atoms.  

A culture of human tissue is being grown in a lab to study mitosis. A solution containing radioactively labelled cytosines was added to the culture in the middle of prophase, and then growth was halted at the end of telophase. Where would the scientists see radioactively labelled DNA? Give reason for your answer
