- Cellulose and glycogen are both polymers of glucose, but they have very different functions. Select all of the statements below that are true (this is a multi-select question). One important difference between cellulose and glycogen is that the cellulose has a(1→6) branches, which greatly increases the "connectiveness" within the structure. One important difference between cellulose and glycogen is that cellulose is a B(14) linked glucan, while glycogen is an a(1→4) linked glucan. The major cause of the functional difference is that glycogen is stored in the cytosol, whereas cellulose is a component of the cell walls. Cellulose is flexible due to the noncovalent interactions between the B(1-4) linked strands of glucose: the polymer can bend without breaking covalent bonds. Cellulose is more "stretchy" than glycogen, since its structure is held together only by the relatively weak hydrogen bonds.arrow_forwardConsider the disaccharide maltose.

(2) The "penultimate carbon" in a monosaccharide is used to determine D- or L-configuration. (3) Sucrose is a reducing sugar and lactose is a nonreducing sugar. O Two of the three statements are true. All three statements are true. O Only one of the statements is true. None of the statements are true.arrow_forward
