NEET BIOLOGY

Detailed explanation-1: -Transport: Molecules, such as proteins, can move from place to place inside the ER, much like on an intracellular highway. Synthesis: Ribosomes that are attached to ER, similar to unattached ribosomes, make proteins.

Detailed explanation-2: -The endoplasmic reticulum (ER) is an organelle responsible for making both membranes and their proteins. It also aids molecular transport through its own membrane. The ER is responsible for protein translocation, which is the movement of proteins throughout the cell.

Detailed explanation-3: -Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes.

Detailed explanation-4: -The ER has been shown to be closely apposed to almost all membrane-bound organelles, including the PM, mitochondria, lipid droplets, Golgi, endosomes, and peroxisomes (Fig.

Detailed explanation-5: -The rough endoplasmic reticulum has many ribosomes on its outer surface and makes proteins the cell needs. The smooth endoplasmic reticulum makes other substances that the cell needs, such as lipids (fats) and carbohydrates (sugars). The endoplasmic reticulum is a cell organelle.
