Answer 1

How do steroid hormones work?

a.) attaching to membrane receptors and triggering chemical reactions.

This can not be true as they can enter the cell and bind to DNA inside the nucleus.

b.) passing into the cell and attaching to receptors inside.

This is the correct answer. As this is the mechanism of their action.

c.) triggering an action potential in the cell.

d.) triggering an influx of potassium ions.

This c and d can be done by the ions only or in neurons.

e.) stimulating endocytosis of hormones and receptors

This doesnot hold true.
