Describe the structure of starch. How does this structure make starch ...
...This shape makes starch well suited to energy storage as it is compact, so takes up little space in the cell, and not very soluble in water, so does not affect the water potential of the cell. 2) Amylopectin: branched chains of ?-glucose monomers joined by 1,4-glycosidic bonds and 1,6-glycosidic bonds....

Describe and explain two features of starch that make it a ... - MyTutor
...Starch molecules consists of two components: Amylose and Amylopectin. Amylose is the straight chained part and amylopectin is the branch chained part. Both these structures enable the starch molecule to coil into a compact shape so that it takes the least possible space and is ideal for storage. Another feature is its capacity of easy conversion....

...In cellulose, alternate glucose monomers are rotated 180 degrees, allowing for an overall straight shape in the molecule, allowing structural conformity and rigidity (cellulose provides structural support in the cell wall).Starch contains branching with branches joined by 1-6 glycosidic bonds: again maximises available space for glucose storage ......

Describe the lock and key theory in reference to the enzyme ... - MyTutor
...The lock and key theory suggests that there is a complimentary shaped substrate that will fit exactly into the specific shape of the enzyme's active site. In this case, amalyase is the enzyme and the substrate is starch. The starch molecule will be complimentary in shape and fit into the active site of Amalyase, so it can be broken down into ......

What are the differences between glycogen, starch and cellulose?
...In addition, the chains in starch and glycogen have a branched structure, i.e. each chain can fork into two. Cellulose on the other hand, is a polymer of beta glucose, and so the polymer forms straight/linear, unbranched chains. These differences in structure underly the different functions of these molecules....
