Question

1. what is the main function of the mitochondria in an animal cell?
2. to break down sugar and release energy that the cell can use

to facilitate cell division
to store waste in the cell
to control which substances enter and leave the cell

Explanation:

Mitochondria are known as the "powerhouses" of the cell. Through cellular respiration, they convert glucose (sugar) and oxygen into adenosine triphosphate (ATP), the energy - carrying molecule of the cell. This process is crucial for the cell to perform various functions such as growth, repair, and movement. Facilitating cell division is more related to structures like centrioles. Storing waste is a function of vacuoles (in animal cells, they are relatively small compared to plant cells). Controlling which substances enter and leave the cell is the function of the cell membrane.

Answer:

To break down sugar and release energy that the cell can use.
