Explanation:

Proteins that control or catalyze chemical reactions are called enzymes.

A substance that assists a compound response with happening is known as an catalyst, and the atoms that catalyze biochemical responses are called enzymes.

Explanation:

Your answer is A.

The repeating stages a cell experiences, including cell division, compose the cell cycle.

Life cycle of the cell (cell cycle) can be divided in interphase and mitotic phase.

Interphase can be subdivided into:

•G1 phase characterized by the growth of the cell

•S where DNA replication occur

•G2 phase final preparation for mitosis.

Mitotic or M phase consists of:

•Prophase-condensation of chromosomes and mitotic spindle formation

•Metaphase-alignment of the chromosomes

•Anaphase- Sister chromatids are  pulled apart by the mitotic spindle

•Telophase-each pole of the cell contain full set of chromosomes.  

Two new cells are formed after cytokinesis.
