Answer:
1. A) powerhouse
2. A) ATP.
Step-by-step explanation:
Mitochondria is called the powerhouse of the cell because they are responsible for releasing energy from the food consumed. This process is commonly referred to as cellular respiration.
when the food is broken down it reaches the cells where chemical reactions takes place. it precisely happens in the cytoplasm of the cell. the cell this way releases 2 molecules of ATP and the mitochondria releases 34 molecules of ATP, this sums of 36 molecules of ATP ( Adenosine TriPhosphate)
The ATP molecules then gives enough energy to the cell to carry out various cellular activities. Some cells require more energy and hence higher number of mitochondria for example muscle cells.
