Question

select the part whose main job is to produce steroid hormones.
mitochondria
cell wall
ribosome
smooth endoplasmic
reticulum

Explanation:

To determine the part that produces steroid hormones, we analyze each option:

• Mitochondria: Produces ATP (energy), not steroid hormones.
• Cell wall: Provides structure (in plants/fungi), not involved in hormone production.
• Ribosome: Synthesizes proteins, not steroid hormones.
• Smooth endoplasmic reticulum (SER): The SER is responsible for lipid synthesis, including steroid hormones (e.g., cholesterol - derived hormones like cortisol, estrogen).

Answer:

smooth endoplasmic reticulum
