16. list and describe three major functions of the smooth er. 1. 2.

Answer

Brief Explanations:

The smooth endoplasmic reticulum (ER) has several key functions. Lipid synthesis occurs here as enzymes create phospholipids and steroids. Detoxification involves enzymes that modify and remove harmful substances like drugs and poisons. Calcium ion storage and release is important for muscle contraction and other cellular processes, as the smooth ER can sequester and release calcium ions as needed.

Answer:

  1. Lipid synthesis: Produces phospholipids and steroids.
  2. Detoxification: Modifies and removes drugs and poisons.
  3. Calcium ion storage and release: Holds and releases calcium for cellular functions like muscle - contraction.
