Question

Mineral activator for enzyme carboxylase in TCA cycle is Fe.

• A. True
• B. False

Answer 1

The correct option is B False

There are various metal ions which act as cofactors or activators of enzymes involved in biochemical pathways. Manganese is the metal which acts as a cofactor for carboxylase enzyme. In +2 oxidation state, it acts as a mineral activator. The metallic ion is required for the activity of pyruvate carboxylase in liver mitochondria and also by oxaloacetate carboxylase in muscles.

So, the statement is false.
