Why is it that steroid hormones use receptors inside of target cells, whereas protein, peptide, and amino acid hormones do not?
A) Steroids can cross the cell membrane because they are lipids and the membrane is lipid.
B) Amino acids and peptide hormones do not have a 3 dimensional structure that can bind to internal receptors.
C) Cells are full of steroid molecules so it is easy for steroid molecules to enter.
D) The target cells affected by steroid hormones have all of their receptors in the cell cytoplasm.
E) All of the answers are correct
