Starch, cellulose, dextran, and glycogen are polysaccharides. How are they similar? To what are their different properties due?
daser333 [38]

Answer:

similarity

Starch, cellulose,dextran and glycogen are all polymers of glucose

differences

                monomer/glucose     glycosidic bond    branching

1.starch              α glucose          1-4 and 1-6               branch and unbranced

  amylose                                       1-4                          unbranched

  amylopectin                               1-4 and 1-6              branched

2. dextran          α glucose          1-6                           branched

3. cellulose        β glucose           1-4                          unbranched, linear        

4. glycogen       α glucose           1-4 and 1-6              branched (shorter

                                                                                     branches than starch)

Enzyme: amlase acts on starch and cellulase acts on cellulose as they are specific for their substrates.

Explanation:

Starch: Consists of both branched amylopectin and unbranched amylose

Enzymes: Enzymes are specific as the gulcose molecule in starch is α and in cellulose is β which differ in their position of hydroxyl groups at anomeric carbon, their structures differ so they form different bonds. Active sites of enzymes can act only on specific bonds a sthey can fit to their specific substrates.

Which of the following describes the role of cyclic AMP (cAMP) in hormone response? A. cAMP receives messages from mRNA to begin
Advocard [28]

Answer:

D

Explanation:

Hormones are bigger than the cell pores hence cannot pass through the cell membrane to influence biochemical processes. Therefore, hormones (such as glucagon and insulin) bind onto receptors on the cell membrane, then transmembrane proteins, such as the G-protein, change conformation activating the secondary messengers inside of the cell. Cyclic- AMP is a major secondary messenger  significant in activating protein kinases.
