People invariably make the same sets of mistakes when they first start shooting video: 1  Trees or telephone poles sticking out of the back of someoneâs head. 2  Interview subjects who are just darkened blurs because there was bright light in the background. 3  Boring shots of buildings with no action.
Best Answer: Protein synthesis (and therefore enzyme synthesis) occurs at the ribosome, and the presence of ribosomes on the ER is what makes it the ROUGH endoplasmic reticulum. The rough endoplasmic reticulum would be the part producing the protein enzymes.
The smooth endoplasmic reticulum lacks ribosomes and functions in lipid metabolism, carbohydrate metabolism, and detoxification of drugs. The smooth ER is especially abundant in mammalian liver and gonad cells. The lacy membranes of the endoplasmic reticulum were first seen in 1945 using electron microscopy.he surface of the rough endoplasmic reticulum (often abbreviated RER or Rough ER) (also called ergastoplasm) is studded with protein-manufacturing ribosomes giving it a rough appearance (hence its name).
