Question

Mineral activator of enzyme aconitase is
a. Mn
b. Mg
c. Fe
d. Cu

Answer 1

Hint: Enzymes activators must be allosteric since they should permit the substrate to tie to the protein for the response to happen. In such a manner, compound activators can be considered as certain allosteric modulators. The particles must tie to a site other than the substrate restricting site, in any case, substrate restricting cannot happen.

Complete answer:
Aconitase is a protein that catalyzes the rearrangement of citrate into cis-aconitate delivering water. The chemical aconitase is a vital participant in the focal pathway of energy creation. As a major aspect of the citrus extract cycle, it changes over citrate into isocitrate. The activity shows histidine going about as a corrosive protonated the hydroxyl on the substrate, permitting it to leave as a water particle.

It is an iron-sulfur protein that capacities both in the TCA cycle just as the glyoxylate cycle. It is otherwise called citrate hydro lyase. The dynamic site of the catalyst comprises 21 amino acids and an iron-sulfur bunch.

The mineral activator required for the catalyst aconitase of the Krebs cycle is iron (Fe). Fe catalyzes the interconversion of citrate and isocitrate, through a cis-aconitate halfway, working in both the carboxyl corrosive (TCA) and glyoxylate cycles.

The iron is a micronutrient required for plants in the biggest sum. It is required for chlorophyll biosynthesis and the action of electron transport proteins in the electron transport chains. It is likewise required as a basic cofactor for the movement of a few compounds, as aconitase.

Hence, the correct answer is option (C).

Additional information:
Manganese assumes a significant function in nitrate decreases. Manganese goes about as an activator for the compound's nitrate reductase and hydroxylamine reductase. Manganese-containing proteins incorporate arginase, pyruvate carboxylase, and manganese superoxide dismutase.

Magnesium is a fundamental cofactor for a compound called DNA polymerase which fixes and recreates strands of DNA utilizing safe nucleotides drifting around in the core.

Copper is a micronutrient ingested as cupric particles by the plants. It is fundamental for the general digestion in plants. Tyrosinase is a copper-containing protein that catalyzes the creation of melanin and different shades.

It is an iron-sulfur protein that capacities both in the TCA cycle just as the glyoxylate cycle. It is otherwise called citrate hydro lyase.
