Vedclass · Answer

(B) Many essential mineral elements are involved in the activation or inhibition of enzymes. $K^+$ (Potassium) is essential for the activation of many enzymes,including those involved in protein synthesis and stomatal opening. $Ca^{2+}$ (Calcium) is involved in the activation of certain enzymes and plays a role in the regulation of metabolic activities. $Mg^{2+}$ (Magnesium) is a crucial activator for several enzymes involved in phosphate metabolism,including those in respiration and photosynthesis (e.g.,RuBisCO and $PEP$ carboxylase). $Zn^{2+}$ (Zinc) is an essential activator for enzymes like alcohol dehydrogenase and carbonic anhydrase. Therefore,the group $K, Ca, Mg, Zn$ is primarily concerned with the activation of various enzymes.
