WebbFoods like potatoes, corn, rice, and wheat are rich in starch. Animals break the starches back down into glucose subunits and convert the glucose into glycogen for storage. Glycogen is a complex storage molecule made from glucose using insulin. Diabetics, who lack insulin, cannot make glycogen so they excrete excess sugar in their urine. WebbStarch is an ideal storage molecule because: it is insoluble and therefore doesn't affect the water potential of the cell. it is large and therefore cannot diffuse from the cell. it is compact and therefore much can be stored in a small space. it is branched and has many ends and therefore can be hydrolysed rapidly by many enzymes at the same time. eat this much jalapeno
