Because both prokaryotic and eukaryotic cells have chromosomes (prokaryotes, and more specifically, bacteria, generally have just one chromosome, but there are some bacteria as well as archaea—which are also prokaryotes—that have multiple chromosomes).

Since the chromosomes are DNA molecules present in both the prokaryotic and eukaryotic cells, it is not a reliable method to determine if a cell is prokaryotic or eukaryotic

The nucleus of a eukaryotic cell is bounded by internal membrane, therefore, it is distinctive.

In contrast, the nucleus of a prokaryotic cell lacks internal membrane, hence its nucleus is not distinctive.

Chromosomes are Deoxyribonucleic (DNA) molecules that carry genetic information of a cell or organism.

The chromosomes are present in both the eukaryotic and prokaryotic cells. Chromosomes present in the eukaryotic cells are called eukaryotic chromosomes while chromosomes present in the prokaryotic cells are called prokaryotic chromosomes.

Since the chromosomes are DNA molecules present in both the prokaryotic and eukaryotic cells, it is not a reliable method to determine if a cell is prokaryotic or eukaryotic

An enzyme is a biological catalyst that seeds up chemical reactions.

A biological catalyst called an enzyme is usually always a protein. It accelerates a certain chemical reaction in the cell. The enzyme is continuously employed during the reaction and is not destroyed. Each enzyme molecule found in a cell is unique and tailored to a particular chemical reaction.

All biological activities in living things involve chemical reactions, and enzymes regulate the majority of them.

Many of these processes would not occur at a noticeable rate without enzymes. Every element of cell metabolism is catalyzed by enzymes.

Therefore, An enzyme is a biological catalyst that seeds up chemical reactions.
