Which of the following is most likely to have the greatest concentration of smooth endoplasmic reticulum?
a cell that secretes enzymes
a cell that destroys pathogens
a cell that makes steroid hormones
a cell that engages in photosynthesis

The correct answer will be option- a cell that makes steroid hormones.

Explanation:

Smooth endoplasmic reticulum or SER is a disklike tubular structure present within the cytoplasmic of the cell.

The SER is smooth as it lacks the protein synthesized structures called ribosomes. Therefore, the SER is involved in many functions depending on the cell it is present like in adrenal glands it secretes steroidal hormones from the cholesterol and in skeletal muscle, it helps the storage of the calcium ions. The SER is the chief component of the cell which secrets steroid hormones.

Thus, the selected option is the correct answer.
