(a)
To explain:- The reasons for different properties shared between cellulose and starch made up of the same repeating subunits.
Introduction: Starch and cellulose are
(b)
To explain: The advantages of α and β linkages in starch and cellulose respectively.
Introduction: Starch and cellulose are polymers of made up of repeating subunits of D-glucose. Cellulose is made up of β 1-4 linkage present in the repeating subunits of D-glucose while starch is made up of α 1-4 linkage present in the repeating subunits of D glucose.

- Meat and potatoes. Compare the structures of glycogen and starcharrow_forwardhe activity. First, you need to prepare a small piece of potato (cut into a 2-inch long stick or wedge), two identical drinking glasses with equal amounts of tap water (enough to submerge the piece of potato) in them and a teaspoonful of table salt. Mark one glass as A, and the other one as B. Dissolve the salt in the water in glass A. Take note of the initial characteristics of the piece of potato, particularly its consistency (degree of firmness or hardness). Record this observation on the first column of table 22. Characteristics before Soaking Table 22: Observed Characteristics of the Piece of Potato Characteristics after Soaking in Salt Water Characteristics after Soaking in Plain Water saline solution (salt water) after an hour and take note of its consistency. Write your observati on the second column of table 22. Place the piece of potato in glass A and set it aside for 1 hour. Remove the potato from th nh General Biology 1 SUBJECT Wayne Ann M.
