Question

If the endoplasmic reticulum were removed from the cell, which organelle would not be able to function properly, and why?
A. mitochondria, because they rely on the ER as an energy source
B. ribosomes, because they receive proteins made by the ER
C. Golgi apparatus, because it packages proteins received from the ER
D. cytoplasm, because it relies on the ER for structural support

Answer 1

Answer:

A. mitochondria, because they rely on the ER as an energy source

Explanation:

A. mitochondria, because they rely on the ER as an energy source

Is the correct answer of this question because ,

Multiple contact points between the ER and mitochondria result in the formation of separate domains known as mitochondria-ER associated membranes (MAMs), which have unique biochemical characteristics and a distinctive collection of proteins.

Skeletal muscle fibres wouldn't be able to contract if the ER were missing. As a result, cells tend to perish when these fundamental and necessary cellular processes are absent.

The endoplasmic reticulum's capacity to fold proteins and destroy improperly folded proteins is also improved by the unfolded protein response. The unfolded protein response also has a failsafe if none of these procedures is able to reduce the protein buildup. The afflicted cells will self-destruct if all else fails.
