Hormone Receptors and Cell Response

The video explains that hormones only affect specific target cells that have the appropriate receptors. These receptors are usually on the cell membrane, but for steroid and thyroid hormones, they are in the cytoplasm. Each cell type expresses different receptors, and only cells with the right receptors respond to a given hormone.

What is the primary reason a hormone affects only certain cells?

• Because they are larger in size

• Because they are located in the bloodstream

• Because they have specific receptors for the hormone

• Because they are closer to the hormone source

Where are the receptors for most hormones typically located?

• Inside the nucleus

• In the Golgi apparatus

• On the cell membrane

• In the mitochondria

Which type of hormones have receptors located in the cytoplasm?

• Amino acid-derived hormones

• Protein hormones

• Steroid and thyroid hormones

• Peptide hormones

What determines whether a cell will respond to a specific hormone?

• The presence of specific receptors for that hormone

• The size of the cell

• The age of the cell

• The location of the cell in the body

How does a hormone affect only one of the cells in a given set?

• By binding to the specific receptors synthesized by that cell

• By being more concentrated in one area

• By being more stable in the bloodstream

• By being larger in size
