Which of these is not true about endoplasmic reticulum

Índice Show

The correct option is CThe endoplasmic reticulum is not responsible for the degradation of cellular wastes.The Endoplasmic reticulum is a large network of membrane-bound tubes and sheets. There are two types of ER: smooth and rough. The RER has ribosomes attached to its surface, while no ribosomes are attached to SER. The RER is involved in the process of protein synthesis. The SER helps in the manufacture of fat molecules, or lipids, important for cell function. One function of the ER is to serve as channels for the transport of materials (especially proteins) between various regions of the cytoplasm or between the cytoplasm and the nucleus. The ER also functions as a cytoplasmic framework providing a surface for some biochemical activities of the cell. The smooth endoplasmic reticulum is responsible for the degradation and detoxification of cellular wastes.

Which of the following is not true about endoplasmic reticulum?

Degradation of cellular material is not a function of endoplasmic reticulum.

Which of the following is true about endoplasmic reticulum?

Answer is B) a, c and d. Endoplasmic reticulum are of two types rough endoplasmic reticulum and smooth endoplasmic reticulum. Function of smooth endoplasmic reticulum includes detoxification of chemicals and poison, carbohydrate metabolism, steroid and lipid synthesis.

Which one is not a part of endoplasmic reticulum?

Mitochondria is not the part of endomembrane system . ER,golgi bodies, lysosomes and vacuoles are part of endomembrane system.

Which of the following statements about endoplasmic reticulum is incorrect?

The main constituent they transport are protiens. Golgi complex is responsible for transportation, packaging, modification of particles required for the functioning of the cell. Therefore, option (c) is incorrect statement and it is not related to Endoplasmic Reticulum.
