Enzymes that utilize ATP in phosphate transfer require an alkaline metal (M) as the cofactor M is​
A. Be
B. Mg
C. Ca
D. Sr

Explanation

Solution

Adenosine Triphosphate (ATP) is the main source of energy in cells in the biological system. ATP is activated due to the presence of magnesium ions. Every enzyme that utilizes ATP in the transfer of phosphate requires an alkaline metal Magnesium as cofactor.

Complete answer:
It must be considered that enzyme reactions depend on pH, temperature, ionic strength and many more factors for enzyme assays. For essential counter ions such as Mg, enzyme reactions are dependent on ATP. If in an assay mixture, only ATP is added without Mg even in sufficient concentration, it can become limiting in the presence of inorganic phosphate or EDTA.
Hence, Mg is essential as a cofactor for almost all enzymes which require ATP for phosphate. Magnesium is the most useful metal in the biological process.

Equilibrium of magnesium is fundamental to prosperity, everything being equal. Magnesium is a moderately plentiful particle in Earth's outside layer and mantle and is exceptionally bioavailable in the hydrosphere. This accessibility, in blend with helpful and strange science, may have prompted its usage in advancement as a particle for flagging, catalyst enactment, and catalysis. Be that as it may, the irregular idea of ionic magnesium has additionally prompted a significant test in the utilization of the particle in natural frameworks. Natural films are impermeable to magnesium (and different particles), so transport proteins must encourage the progression of magnesium, both into and out of cells and intracellular compartments.

So, the correct answer is option B.

Note:
Chlorophyll in plants changes water over to oxygen as O2. Hemoglobin in vertebrate creatures transports oxygen as O2 in the blood. Chlorophyll is fundamentally the same as hemoglobin, aside from magnesium is at the focal point of the chlorophyll particle and iron is at the focal point of the hemoglobin atom, with other variations. This cycle continues living cells on earth alive and keeps up pattern levels of CO2 and O2 in the climate.
