Compare the mechanism of action of a steroid and a protein-type hormone at the cellular level.
Steroid Hormone
Lipid-based hormones that pass through cellular membranes and bind to specific receptors to alter gene expression.
Protein-Type Hormone
Hormones that are composed of chains of amino acids and interact with cell surface receptors; they include insulin and growth hormones.
Cellular Level
The level of organization that includes cells, the basic structural and functional units of all living organisms.
- Understand the distinct roles and functions hormones fulfill within the human body.
- Develop an understanding of the dynamics of hormone action, including aspects related to signal transduction pathways.

Final Answer :
Steroid hormones are lipid soluble and, therefore, pass through the plasma and nuclear membranes to combine with nuclear receptors. This interaction results in the synthesis of new proteins. Protein hormones combine with plasma membrane cell receptors and initiate a signaling cascade involving protein activation that will produce an alteration of cell activity.
