Using the lock and key theory explain how the enzyme amylase is specific for breaking down starch

Amylase is an hydrolytic enzyme which is present in our saliva to digest polysaccharide such as starch.

Explanation:

Lock and Key model was proposed by Emil Fisher.According to this model a substrate binds to an enzyme same as a key binds to a lock.

    In simple words it means each lock is specific for a particular key by the same way each enzyme is specific for a particular substrate,

  Now comming to the matter of starch that contains glucose monomers which are linked together by alpha-1,4-glycosidic linkage.

 Salivary alpha amylase cleaves the alpha 1,4 glycosidic linkage present between the glucose residues to generate alpha limit dextrin,maltose and maltitriose.

    That means amylase is specific only for alpha 1,4 glycosidic linkage.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
