Question

enzymes that utilise ATP in phosphate transfer require an alkaline metal (M) as the cofactor.M is​

Answer 1

Answer:

Mg

Explanation:

For enzyme assays it must be considered that enzymes reactions depend on more factors than pH, temperature and ionic strength.

Enzyme reactions dependent on ATP need Mg as essential counter ions.

If only ATP without Mg is added to the assay mixture even in sufficient concentration, it can become limiting, especially if complex compounds, like inorganic phosphates or EDTA are present.

so Mg is requires as cofactor for enzymes which utilise ATP in Phosphates.

enzymes that utilise ATP in phosphate transfer require an alkaline metal (M) as the cofactor is Mg

Answer 2

Enzymes utilize Mg as a co factor

Explanation:

Mg is a most useful alkaline earth metal in biological process.

• In biological systems, ATP (adenosine triphosphate) which is the main source of energy in cells is in active state due to containing Magnesium ion.

• Thus, enzymes that utilize ATP in phosphate transfer require an alkaline metal Magnesium as the cofactor.  

• Hence M is Mg
