Question

What is the role of the enzyme phosphatase in the mineralization of organic phosphorus in the soil?

The phosphatase enzyme is responsible for the release of phosphate into the soil solution by dephosphorylating any organic phosphorus compound present in the soil.
The activity of phosphatase can contribute to increasing the availability of phosphorus to plants, especially in the rhizosphere.
Phosphatase is produced only by microorganisms in the soil.
a) Only I is correct.
b) Only II is correct.
c) Only I and II are correct.
d) Only II and III are correct.
e) I, II, and III are correct.

Ed · Answer

A resposta correta é a alternativa (c) Only I and II are correct.

A enzima fosfatase é responsável pela liberação de fosfato na solução do solo, desfosforilando qualquer composto de fósforo orgânico presente no solo. A atividade da fosfatase pode contribuir para aumentar a disponibilidade de fósforo para as plantas, especialmente na rizosfera. Além disso, a fosfatase é produzida apenas por microorganismos no solo. Portanto, as afirmações I e II estão corretas. A afirmação III é incorreta, pois a fosfatase é produzida apenas por microorganismos no solo e não por plantas.
