ANIMAL REPRODUCTIVE PHYSIOLOGYintermediate
Select ALL actions through which hormones can affect target cells, according to the slides.
Answer
Alter rates of enzyme-mediated reactions, Control movement of molecules across the plasma membrane, Regulate the rate of gene expression
Explanation
The first three options reproduce the actions listed in the material: changing enzyme-mediated reaction rates, controlling movement across the plasma membrane, and regulating gene expression, which affects protein production. The slides do not say hormones convert target cells into endocrine cells.\n\n**Key takeaway:** Hormonal effects can occur through enzyme activity, membrane transport, or gene-expression regulation.\n\n**Glossary:** **Gene expression**: Use of genetic information to produce functional products, including proteins; **plasma membrane**: The boundary surrounding a cell.
