Question

What would happen to a cell that lacked smooth endoplasmic reticulum?(1 point)

Its cell membrane would be impermeable.

It would not be able to produce tRNA.


It would not be able to make lipids.

It would not be able to replicate DNA.

Answer 1

Answer:

Without the RER the cell is not able to synthesis new plasma membrane proteins, lysosomal enzymes, proteines for the Golgi apparatus and proteins for extracellular secretion. Because these kind of proteins are synthesised in the RER.

The smooth ER has an important role in lipid and steroid synthesis, it is a storage for intracellular calcium as well. Without ER in the skeletal muscle fibers couldn’t happen muscle contraction.

In the absence of these cellular mechanisms the cell would probably die.

Maybe the most deadly

Answer 2

Answer:

It would not be able to make  lipids.

Explanation:

Smooth endoplasmic reticulum is important for synthesizing a lipids.Hence  reduction in it causes a reduction in lipids.
