Biology Endocrine System aka hormones

Question 1

Peptide

Answer 1

Protein that can’t diffuse

Bind to receptors on membrane surfaces. Use secondary messengers

Question 2

Steroids

Answer 2

Lipids-non polar

Diffuse through the membrane and act in the nucleus

Question 3

Tyrosines

Answer 3

Both ways

Thyroids diffused into nucleus/ Catecholamines act on receptors at the membrane
