An atpase enzyme breaks down atp into adp and phosphate using water in the reaction. this enzyme is in the enzyme class

The correct answer is-

Hydrolase.

Hydrolase is a class of enzyme that includes biochemical catalysts, which ulitize water to break down any chemical bond (a process called hydrolysis).

In other words, any enzyme that hydrolyzes a substrate belongs to Hydrolase class of enzymes.

In this question, enzyme ATPase catalyses hydrolysis of ATP in order to form ADP and inorganic phosphate to (with the help of water) along with the release of large amount of energy.

Thus, it belongs to Hydrolase class of enzyme.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
