GENERAL HISTOLOGY

Detailed explanation-1: -The endoplasmic reticulum (ER) is a series of interconnected membranous sacs and tubules that collectively modifies proteins and synthesizes lipids. However, these two functions are performed in separate areas of the ER: the rough ER and the smooth ER.

Detailed explanation-2: -The endoplasmic reticulum (ER) is a network of membrane-enclosed tubules and sacs (cisternae) that extends from the nuclear membrane throughout the cytoplasm (Figure 9.1).

Detailed explanation-3: -Golgi body is made up of flat, membrane-enclosed sacs and functions as a processing centre for proteins synthesised in the ribosomes.

Detailed explanation-4: -The smooth endoplasmic reticulum in hepatocytes (which are able to store glycogen) contains the enzyme glucose-6-phosphatase, which converts glucose-6-phosphate to glucose, a step in gluconeogenesis.

Detailed explanation-5: -The endoplasmic reticulum (ER) is the organelle that occurs as interconnected network of flattened sacs or tubules called cisternae in the cytoplasm.
