Both starch and cellulose are polymers of glucose. Why is one, starch, readily digestible by a variety of organisms, including humans and the other digestible by a limited number of organisms? What prevents cellulose from being digested by most organisms? Locate another polymer that exhibits similar properties, and describe it here.

Cellulose could provide an abundant and cheap form of glucose for humans.

Cellulose could provide an abundant and cheap form of glucose for humans. Why is cellulose not a source of nutrients for humans? Animals use starch and glycogen as an energy source, whereas plants use cellulose for energy. Cellulose digestion must occur in a basic environment, but the human gut is acidic. Humans cannot absorb the hydrolyzed form of cellulose. Humans, and most vertebrates, lack the enzyme cellulase. Vertebrate enzymes are unable to hydrolyze ( 1-4) linked glucose monomers.

Poplar wood contains 50% cellulose. Pure cellulose extracted from wood can enzymatically be converted to glucose C6H12O6 with 90% efficiency. Write down a balanced chemical reaction for the conversion of glucose to ethanol (CH3CH2 OH). Use this equation to calculate the theoretical yield of ethanol from one-ton of poplar wood. Calculate the actual yield of ethanol from one-ton of poplar wood if the fermentation efficiency (glucose to ethanol) is 95%. Determine the gasoline equivalent of ethanol in part C above.

In a dialysis experiment with a dialysis full of glucose/starch solution in a beaker of water (tested starch with iodine)- Which solutes would cross the membrane? Why were these solutes able to cross and not others? Do you have evidence that dialysis occurred? Explain. Do you have evidence that osmosis occurred? Explain. Can dialysis and osmosis occur at the same time? Why or why not?
