Lesson 24.3 - Types of Hormones

Question 1

These are lipid-soluble hormones derived from cholesterol. They help control salt and water balance, metabolism, immune functions, and inflammation.

Answer 1

Steroid Hormones

Question 2

Steroid Hormones

Answer 2

These are lipid-soluble hormones derived from cholesterol. They help control salt and water balance, metabolism, immune functions, and inflammation.

Question 3

Types of Hormones

Answer 3

steroid hormones
protein and peptides
amino acid derivatives

Question 4

These are soluble in lipids. They are insoluble in water and carried by transport proteins in blood. They are important for cell membranes in maintaining its fluidity and signaling molecules.

Answer 4

Steroid Hormones

Question 5

Steroid Hormone Example

Answer 5

Cortisol is a steroid hormone that helps to regulate metabolism and immune response.

Question 6

It is also known as the “stress” hormone.

Answer 6

Cortisol

Question 7

_____________, the “emergency” hormone

Answer 7

Epinephrine or Adrenaline

Question 8

These are composed of amino acids linked via peptide bonds and form short polypeptide chains. They regulate growth and development.

Answer 8

Peptide and Protein Hormones

Question 9

Peptide and Protein Hormones

Answer 9

These are composed of amino acids linked via peptide bonds and form short polypeptide chains. They regulate growth and development.

Question 10

Examples of Peptide and Protein Hormones

Answer 10

antidiuretic hormone (ADH) and oxytocin released by the posterior pituitary gland. And insulin of the pancreas

Question 11

_________, the “cuddle” hormone or “love” hormone

Answer 11

Oxytocin

Question 12

• These are small molecules derived from the amino acids tyrosine and tryptophan.
• Their chemical name ends with “-ine.”
• They are promoters of metabolism and immunity.

Answer 12

Amino Acid Hormones

Question 13

Amino Acid Hormones

Answer 13

• These are small molecules derived from the amino acids tyrosine and tryptophan.
• Their chemical name ends with “-ine.”
• They are promoters of metabolism and immunity.

Question 14

Examples of Amino Acid Hormones

Answer 14

Epinephrine, norepinephrine, and adrenaline synthesized in the adrenal medulla. And thyroxine produced by thyroid gland

Question 15

Hormones vary in solubility in aqueous and lipid environments. Types of Hormones based on Solubility.

Answer 15

hydrophilic hormones
hydrophobic (lipophilic) hormones

Question 16

Hydrophobic Hormones

Answer 16

They are “lipid-loving” hormones that have high lipid solubility but low water solubility.

Question 17

Hydrophobic Hormones Examples

Answer 17

thyroid hormones
steroid hormones

Question 18

Hydrophilic Hormones

Answer 18

They are “water-loving” hormones but have low lipid solubility.

Question 19

Answer 19

peptide and protein hormones
amines with catecholamines and indolamines

Question 20

Answer 20

fixed receptor mechanism

Question 21
