The ΔG for the following equation is +34 kcal. a. Is this reaction exergonic or endergonic?  b. Which direction should the arrow go? (will the reaction proceed in the forward or the reverse direction) CH4 + 2 O2 ——-> CO2 + 2 H2O

Differentiate between the structure of chromatin and chromosome form of DNA. And explain when is DNA present in the chromatin form and when it is in the chromosome form during the life cycle of a cell and explain why?  

Explain what structural properties of triacylglycerols makes them a storage form of fatty acids in adipose tissues. 

Blood types are designated A, B, AB, and O depending on the glycoprotein presented on the surface of the red blood cells. If person A has glycoproteins IA and IB and person B has IO and IA. What is the person’s blood type?

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
