input with options: Answer the following question given this paragraph: Steroid hormones are made of lipids, such as phospholipids and cholesterol. They are fat soluble, so they can diffuse across the plasma membrane of target cells and bind with receptors in the cytoplasm of the cell (see Figure below ). The steroid hormone and receptor form a complex that moves into the nucleus and influences the expression of genes, essentially acting as a transcription factor. Examples of steroid hormones include cortisol and sex hormones. Q: What are steroid hormones made of? A:
OPTIONS:
- water
- amino acid
- organisms
- lipids
output:
lipids
