Question

Classify each phrase on the left into the correct hormone category: water-soluble hormones, lipid-soluble hormones, or both types of hormones.

Cell response occurs within minutes Hormone travels in bloodstream to target cells Water-soluble hormones Lipid-soluble hormones Both types of hormones Activate a second messenger system Bind to receptors on target cell membrane Hormone is released by endocrine cells Bind to receptors on target cell membrane Peptide hormones Hormone enters target cell and binds to receptor inside cel Steroid hormones messenger Cell response requires new gene transcription Hormone binds to a receptor protein

Answer 1

Answer:- Water soluble hormones----) 1.Activate second messenger system.

Reason--- water soluble hormone after releasing by endocrine glands reached target cell by travelling through bloodstream and they cannot passed the lipid bilayer of plasma membrane by the process of diffusion so they bind receptors on target cell membrane and activate second messenger system.

2. Bind receptors on target cell membrane.

Reason:- water soluble hormone cannot enter into the cell by diffusion so they bind to receptor on target cell membrane.

3.Peptide hormone

Reason:- Peptide hormone is water soluble hormone.

Lipid soluble hormone:------) 1.steroid hormone.

Reason:- Steoroid hormone are very important lipid soluble hormone. Testosterone, estrogen, progesterone, aldosterone, cortisol etc are important lipid soluble hormone and these are example of steroid hormone.

2. Hormone enters target cell and binds to receptor inside cell.

Reason-- Lipid soluble hormone operate their action by reaching target cell through diffusion via plasma membrane and bind to receptor protein.

3. Cell response requires new gene transcription.

Reason:- lipid soluble hormone can directly enter into cell by diffusion and can bind to DNA to regulate gene transcription mechanism.

4. Cell response occurs within minutes.

Reason :- Lipid soluble hormone enter into cell by diffusion and bind to receptor protein inside cell so cell response occurs within minutes.

Both types of hormone -----) 1. Released by endocrine glands.

Reason:- all hormones whether it is water soluble or lipid soluble are released by endocrine glands of our body.

2. Hormones travels in bloodstream to Target cell.

Reason-- all hormone produced by endocrine glands after pouring into blood , they travel in bloodstream to reach their target cell.

3. Hormone bind to receptor protein.

Reason---) All hormone bind to receptor protein but they bind to surface receptor or plasma membrane receptor protein in case of water soluble hormone and incase of lipid soluble hormone they bind to receptor protein inside cell after entering cell by diffusion .
