Which of these organelles prepares proteins to be fully functional

Answer;

Rough endoplasmic reticulum

Explanation;

Rough endoplasmic reticulum is among the organelles that are found in eukaryotic cells. The reason as to why it is called rough is because it has ribosomes attached to its surface.

Its main function is to produce proteins. It is made up of cisternae, tubules and vesicles. The cisternae consists of flattened membrane disks, which are involved in the modification of proteins.

Once enough proteins have been synthesized, they are transferred from the Rough endoplasmic reticulum to the Golgi apparatus via membrane-bound vesicles.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
