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.
In liver cells the smooth ER produces enzymes that help to detoxify certain compounds. In muscles the smooth ER assists in the contraction of muscle cells, and in brain cells it synthesizes male and female hormones. The endoplasmic reticulum is only one component of a cell.ypically, the smooth ER is a tubule network and the rough ER is a series of flattened sacs. The space inside of the ER is called the lumen. The ER is very extensive extending from the cell membrane through the cytoplasm and forming a continuous connection with the nuclear envelope.
