Question
Chapter 20, Problem 20.16E
Interpretation Introduction
Interpretation:
The typical inorganic ions that serve as cofactors are to be listed.
Concept introduction:
Enzymes are the biocatalysts. Enzyme enhances the activity of biochemical process. It requires cofactors for catalytic action. Cofactors are the non-protein parts. Cofactors can be inorganic or organic molecules.

octet rule.
The symbols of the problem atoms are:* ☐
Yes.
No, it has the wrong number of valence electrons.
The correct number is: ☐
No, it has the right number of valence electrons but doesn't satisfy the
octet rule.
The symbols of the problem atoms are:* |
Yes.
No, it has the wrong number of valence electrons.
The correct number is:
No, it has the right number of valence electrons but doesn't satisfy the
octet rule.
The symbols of the problem atoms are:* |
If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many
times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "0,0".
