Question

Bioenergetics Graph the free energy of the following reactions. (for an example of a graph like this please see our slides from the enzyme lecture. 4 pts 8. free energy a. Using a dashed line, draw the energy diagram for the exothermic reaction ATP Pi + ADP b. Using a solid line, draw an energy diagram for the endothermic reaction fructose-P + Pi fructose-2P c. How can an enzyme catalyze the reaction progress of reaction (time) you depicted in part b? Please answer in 1-2 complete sentences. 9. (2 pts) if you had a cell that contained 5% glucose and would only allow water through its membrane, and you put it into the following solutions describe which direction water would flow and what would happen to the cell? a. b, c. d, Water 2.5% NaCL 2.5% fructose 2% sucrose; 2% KCL 10. (lptl Glucose can be used as a monomer to produce two different polymers, starch and cellulose what is the molecular difference between these two. cellulose and starch are just polymers of glucose, why can we only get glucose from starch while cellulose can not be digested by our bodies? What is missing for cellulose?

Explanation / Answer

Ans 11. Since starch and cellulose both are formed from tha glucose monomers but their is a structural arrangement difference between then as in starch the gluscose have an alpha linkage whereas in case of cellulose linkage is beta 1-4 glycosidic linkage hence such structural configuartion makes it undigestible by humans because humans lack the enzyme cellulase that would allow the breakage of beta 1-4 linkage.
