Question

Transporting channels of the cell_____________.

Answer 1

Endoplasmic reticulum:

1. The endoplasmic reticulum (ER) is a network of sac-like structures and tubes found in a cell's cytoplasm (gel-like fluid).
2. ER is divided into two types: RER and SER. Rough ER is referred to as RER, whilst Smooth ER is referred to as SER. Ribosomes are found in the rough ER and help with protein synthesis. ERs play a range of tasks in cells.
3. One of their key responsibilities is to act as a mode of transportation. Secretory proteins, generally glycoproteins, are transported across the endoplasmic reticulum membrane.

Final answers:

Transporting channel of the cell is the Endoplasmic reticulum.
