rough endoplasmic reticulum

- connected to ribosomes. The rough ER is responsible for processing and altering proteins: · The proteins are converted from primary to tertiary structure. · Portions of carbohydrate can be added to the proteins. · The proteins can be incorporated into the ER itself.

smooth endoplasmic reticulum

- lacks ribosomes and functions in the synthesis of phospholipids and steroids. Cells that have a lot of smooth ER can detoxify cells exposed to chemicals of the body

Which of the following statements is false? a. The ER is continuous with the nuclear envelope. b. Rough ER is rough because of the presence of ribosomes. c. Smooth ER functions in lipid synthesis. d. Proteins manufactured in the rough ER are secreted into the cytoplasm.

- d. proteins manufactured in the rough ER are secreted into the cytoplasm
