Question

Which of the following is a function associated with the smooth endoplasmic reticulum in at least some cells?

1) synthesis of steroid hormones
2) glycosylation of proteins
3) sequestration of calcium Ca₂⁺ ions within the cisternal space
4) a and b
5) a and c

Answer 1

The smooth endoplasmic reticulum (SER) is involved in the synthesis of lipids and steroid hormones, as well as the storage and regulation of cellular calcium ions.

Step-by-step explanation:

One of the main functions of the smooth endoplasmic reticulum (SER) is in the synthesis of lipids and steroid hormones. It also plays a role in the storage and regulation of cellular calcium ions and metabolizes some carbohydrates.

The smooth ER is particularly abundant in cells that produce large quantities of steroid hormones, such as those found in the female ovaries and male testes.
