Explanation

A holoenzyme is the complete, active enzyme, formed when an apoenzyme (protein part) binds with its cofactor or coenzyme.

It consists of a polypeptide chain plus non-protein component, making it catalytically active.

Explanation

In beta decay (β⁻ emission), a neutron in the nucleus converts into a proton and emits a beta particle (electron).

This increases the atomic number by 1, but the atomic mass remains nearly the same.

Explanation

The margin of the prothallus (the gametophyte stage of Adiantum) is typically one cell thick.

This thin edge helps in gas exchange and absorption, important for the fern’s reproduction and development.

Explanation

 An optical instrument uses lenses or mirrors to manipulate light,

Explanation

One mole of any compound contains 6.02x10^23 molecules of that compound. 

In one molecule of SO2, there is one sulfur atom and two oxygen atoms. 

Therefore, one mole of SO2 contains 6.02x10^23 sulfur atoms. 

Explanation

Cytosol is the soluble, fluid portion of the cytoplasm where organelles are suspended.

It plays a key role in metabolic reactions, transport, and cell signaling within the cytoplasm.

Explanation
