Answer:
Mitochondria
Explanation:
MITOCHONDRIA:They are usually sausage shaped organelles, but some may be round or threadlike. Each mitochondrion is covered by a double helix membrane; the inner being folded to form partitions projecting into the cavity of the mitochondrion. These portions are called a Cristae. Inside the mitochondrion, there are enzymes required for citric acid cycle.
Mitochondria is the *powerhouse of the cell*;it is a site for oxidation phosphorylation and electron transport(i.e, cellular respiration).
*Mitochondria acts like the digestive system in the human body* which takes in nutrients, breaks them down, and creates energy rich molecules for the cell... *So also is the mitochondria with its own* enzymes .. *They are organelles that keeps the cell full of energy*.
So, mitochondria acts like the digestive system in the human body.
