Susan was examining a cell under the microscope and noticed the formation of a cell plate in the midline of the cell and the formation of nuclei at opposite poles of the cell. The cell under examination was most likely a(n):

A plant cell

Explanation:

In the given question, a stage of a cell has been described during cell division.

The characteristic of this cell division are:

1. Nuclei are formed at opposite poles- shows that it is the stage of cell division

2. The formation of cell plate- the cell plate is formed in the middle of the cell which indicates that the cell is a plant cell.This cell is a plant cell as the cell plate is formed only in the plant cells and not in the animal cell in which the contractile rings are formed.

Thus, A plant cell is correct.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
