Question
Match the feature of the hormone with the correct hormone type.Made up of lipid molecules.Answer 1 Question 19Circulate freely in the blood.Answer 2 Question 19Cause a physiological effect via production of new proteins.Answer 3 Question 19Cannot easily diffuse across cell plasma membranes.Answer 4 Question 19
Solution
-
Steroid Hormones: These hormones are made up of lipid molecules. They can easily diffuse across cell plasma membranes because lipids are fat-soluble.
-
Peptide Hormones: These hormones circulate freely in the blood. They are water-soluble and therefore cannot easily diffuse across cell plasma membranes.
-
Steroid Hormones: These hormones cause a physiological effect via the production of new proteins. They do this by binding to receptors inside the cell, which triggers the production of proteins.
-
Peptide Hormones: These hormones cannot easily diffuse across cell plasma membranes. They bind to receptors on the surface of the cell and trigger a series of reactions inside the cell.
