Which of the following is a co-factor and tightly bound to the apoenzyme?

Which of the following type of cofactors are tightly bound to the apoenzyme

Which of the following is the most stable nucleus?

Fill ups: A…………………is a material in which all the electrons are tightly bound to the nuclei of atoms.

Which of the following organisms contain well-defined nucleus and membrane -bound organelles ?

The energy required to pull the most loosely bound electrons from an atom is known as ionization potential. It is expressed in electron volts. The value of ionization potential depends on three factors :(i) the charge on the nucleus (ii) the atomic radius and (iii) the screening effect of inner electron shells. Which of the following elements has the least ionization potential?

Number of unit membranes that bound the nucleus are
