Verified step by step guidance

Understand the role of hormones: Hormones are chemical messengers that travel through the bloodstream to tissues and organs, affecting various physiological activities.

Identify how hormones interact with target cells: Hormones can bind to specific receptors on the surface or inside target cells, initiating a series of cellular events.

Explore the mechanism of action: Hormones can alter the permeability of the cell membrane, allowing or restricting the flow of ions and molecules, which can change the cell's activity.

Consider genetic influence: Some hormones can enter the cell and interact with the DNA, influencing gene expression and protein synthesis, but they do not directly alter the DNA sequence.

Evaluate metabolic effects: Hormones can affect cellular metabolism, such as increasing the number of mitochondria or influencing the conversion of glucose to ATP, but they do not convert glucose directly into ATP.
