Answer
Nishtha and Prakriti
Reason
| Student | Enzymes Named | Substrate Type | Result |
|---|---|---|---|
| Nishtha | Amylopsin acts on starch Invertase acts on sucrose | Both are carbohydrates | Correct |
| Ankur | Steapsin acts on fats Maltase acts on Maltose (carbohydrate) | One enzyme does not act on carbohydrate | Incorrect |
| Prakriti | Ptyalin (salivary amylase) acts on starch Amylopsin acts on starch | Both are carbohydrates | Correct |
| Aakash | Maltase acts on Maltose (carbohydrate) Erepsin acts on Proteins | One enzyme does not act on carbohydrate | Incorrect |
Therefore, only Nishtha and Prakriti supplied two enzymes that each act on some form of carbohydrate.
