answer 5
Mitochondria is called the powerhouse of cell. They are so called because they carry out the process of aerobic respiration and generate the energy molecules (ATP or adenosine Triphosphate) for cell operation. Mitochondria oxidize pyruvate (obtained from glucose) and NADH (generated in ctyosol). Pyruvate oxidation takes place through the process known as Krebs cycle or citric acid cycle. A proton gradient is established across the cell membrane during aerobic respiration, which is beneficially employed to generate ATP molecules from ADP. Aerobic respiration is a preferred mechanism as compare to anaerobic respiration. Aerobic respiration can generate up to 38 ATP molecules from glucose. In comparison, the energetic yield of anaerobic respiration is much lower at 2 ATP molecules (per molecule of glucose metabolized).

Lipids present in the cell membrane are synthesized in the smooth endoplasmic reticulum which does not contain the ribosomes. However, the proteins are produced in the rough endoplasmic reticulum, which is called so because it has the ribosomes attached to the endoplasmic reticulum. Ribosomes help in protein synthesis.

An amoeba eats tiny plants and animals present in pond water where it lives. An amoeba takes in food by extending arm-like structures called pseudopodia from any part of its body, since it is shapeless.
When a food particle comes near the amoeba, then the amoeba produces two pseudopodia around the food particle and surrounds it.
The two pseudopodia then join around the food particle and trap it in a food vacuole with a little water. The food vacuole contains digestive enzymes which break down the food into nutrients and undigested waste.
The nutrients from the food are directly absorbed by the body of the amoeba, the cytoplasm. The undigested wastes are simply thrown out of the body through a rupture anywhere in the cell wall.
