Question

Why are constitutive enzymes synthesised continuously by the cell?

Options

• Because excess end product keeps switching their genes ON

• Because they require a specific inducer or substrate to be synthesised

• Because they are only needed during anabolic biosynthetic pathways

• Because they are essential for basic cellular metabolism

Answer 1

Constitutive enzymes are produced all the time because they are essential for basic cellular metabolism. Their continuous synthesis supports fundamental cellular functions regardless of substrate or product levels.
