(c) Proteins in mammalian cells are synthesised in rough endoplasmic reticulum
Mammalian cells are cells that are derived or isolated from tissues of a mammal.
They are Eukaryotic cells that contain a membrane-bound nucleus and vast cub cellular compartments called organelles.
They maintain their shape due to the Cytoskeleton which is composed of the microtubulus, intermediate filaments, and microfilaments within the cytoplasm.
Cytoplasmic ribosomes that are associated with the rough endoplasmic reticulum synthesis particular membrane and all organelle proteins and the majority of proteins, all proteins that are then secreted out of the cell.
In Mammalian cells, proteins are not synthesized in the cell membrane.
Rough Endoplasmic Reticulum (RER), present in the Ribosome is responsible for the synthesis and packaging of proteins.
