the graph illustrates the relative activity levels of three common digestive enzymes, where 0 represents no activity and 12 represents the highest level of activity. which enzyme is most active at a neutral ph of 7? ⇔β⇔∅⇔β

Amylase

Explanation:

Amylase is a digestive enzyme present in the saliva secreted by salivary glands and secreted by the pancreas. This enzyme acts in a neutral medium at pH 7.  Amylase converts carbohydrates to maltose. Pepin performs the digestive function in acidic medium and trypsin in alkaline medium. Therefore, amylase is active at neutral pH 7.
