Final answer:

The SER does not contain the enzyme catalase, which is instead found in peroxisomes. It is involved in steroid hormone synthesis, calcium storage, and detoxification in liver cells, but not in forming transport vesicles for protein movement.

Step-by-step explanation:

The question asks which of the following is NOT a property of smooth endoplasmic reticulum (SER). The correct answer to this question is that the SER does not contain the enzyme catalase; this enzyme is found in peroxisomes, not the SER. The SER is involved in several key cellular functions such as steroid hormone synthesis, storing calcium, and in liver cells, it does contain detoxifying enzymes.

Furthermore, SER is known for lipid synthesis, but not for forming transport vesicles for moving proteins; that function is associated with the rough endoplasmic reticulum (RER), which has ribosomes attached to it and is involved in protein synthesis and transport.
