Answer 1

Amidon preparat -> maltoza (amilaza salivara)
Amidon crud -> maltoza (amilaza pancreatica)
Dizaharide -> monozaharide (dizaharidaze)

Question 2

Transformari chimice ale lipidelor

Answer 2

Lipide emulsionate din lapte, frsica, oua -> acizi grasi si glicerina (lipaza gastrica)
Lipide emulsionate -> acizi grasi si glicerol (lipaza pancreatica)
Lipide -> acizi grasi si glicerol (lipaza intestinala)

Question 3

Transformari chimice ale proteinelor

Answer 3

Proteine -> albumoze si peptone (pepsina)
Albumoze si peptone -> peptide (tripsina si chimotripsina)
Peptide -> tripeptide si dipeptide (carboxipeptidaze)
Tripeptide si dipeptide -> aminoacizi (peptidaze)
Cazeinogen -> paracazeinat de calciu (labferment)
Gelatina -> gelatina lichefiata (gelatinaza)
Proteine fibroase -> proteine fibroase hidrolizate (elastaza)
