What type of protein is a chemical messenger that travels in the blood?
The type of protein that acts as a chemical messenger and travels in the blood is known as a hormone. Hormones are produced by various glands in the endocrine system and play a crucial role in regulating various physiological processes in the body. These proteins bind to specific receptors on target cells to initiate a cellular response.
Which type of hormone requires a second messenger?
Peptide or protein hormones require a second messenger to transmit their signal inside the cell. Upon binding to their receptor on the cell surface, these hormones activate intracellular signaling pathways that use second messengers like cAMP or Ca2+ to propagate the signal and elicit a cellular response.
The central dogma of molecular biology is centered upon the process of protein synthesis in which the information from DNA is transcribed and translated resulting in multiple amino acids being joined?
The central dogma of molecular biology describes the flow of genetic information from DNA to RNA to protein. It begins with transcription, where DNA is used as a template to synthesize messenger RNA (mRNA). This mRNA is then translated into a specific sequence of amino acids, forming a protein. The resulting protein can perform various functions in the cell, ultimately determining the organism's traits.
What is the difference between protein hormones and steroid hormones and how they communicate with their target cells?
Steroid hormones arelipid-soluble and can dissolve easily into the cell membrane of the target cell to connect with receptors. Protein hormones are water-soluble and connect with receptors at the membrane because it can't diffuse through the membrane.
What role does cyclic AMP play for most hormones?
Cyclic AMP (cAMP) serves as a second messenger for many hormones. When hormones bind to their specific receptors on the cell membrane, it triggers a cascade of biochemical events that lead to the production of cAMP. cAMP then activates other signaling molecules, such as protein kinase A, which regulate various cellular processes, including gene expression, metabolism, and cell growth.
What is the link between a first messenger and a second messenger in a cell that responds to peptide hormones?
Peptide hormones bind to cell surface receptors, activating signaling pathways that involve the generation of second messengers within the cell. The first messenger (peptide hormone) triggers the activation of specific proteins or enzymes that then generate the second messenger molecules, such as cyclic adenosine monophosphate (cAMP) or inositol trisphosphate (IP3), initiating a cascade of cellular responses.
What type of protein is a chemical messenger that travels in the blood?
The type of protein that acts as a chemical messenger and travels in the blood is known as a hormone. Hormones are produced by various glands in the endocrine system and play a crucial role in regulating various physiological processes in the body. These proteins bind to specific receptors on target cells to initiate a cellular response.
Which class of hormones uses second-messenger systems?
if im not mistaken, the classes of hormones that use secondary messenger system are water soluble, nonsteroidial hormones. With this being said, all hormones that use the secondary system are protein and peptide based hormones. The cell membrane is composed phosholipid bilayer with cholestoral embedded in the membrane to allow for flexible movement.
Are protein hormones?
Yes, hormones are proteins with specific structure
Which type of membrane protein attaches to specific hormones such as insulin?
The type of membrane protein that attaches to specific hormones such as insulin is a receptor protein. Receptor proteins are specialized proteins located on the cell membrane that recognize and bind to specific molecules such as hormones, triggering a cellular response. In the case of insulin, its receptor protein on the cell membrane binds to insulin, leading to cellular uptake of glucose and other metabolic responses.
What is specific function of t3 thyroid hormone?
T3 and T4 hormones regulate the metabolism, protein synthesis and sensitivity to other hormones in the body.
The correct order of molecules involved in protein synthesis is?
The correct molecular involved in protein synthesis is DNA, messenger RNA, transfer RNA, and polypeptide. When a DNA is read, it produces a messenger RNA, amino acids are then matched with codons (transfer RNA) forming chains of polypeptides.
What are the key characteristics and functions of protein domains and motifs in molecular biology?
Protein domains are distinct sections of a protein that have specific functions, such as binding to other molecules or catalyzing chemical reactions. Motifs are smaller, recurring patterns within protein sequences that also have specific functions. Both domains and motifs play crucial roles in determining a protein's structure and function in molecular biology.
Why do protein hormones need second messenger to activate target cell?
Protein hormones that need second messenger to activate a target cell are hydrophobic. They therefore need these second messengers in order to penetrate into the cell membrane. steroid hormones are hydrophilic so they do not need second messengers.
Which type of hormone requires a second messenger?
Peptide or protein hormones require a second messenger to transmit their signal inside the cell. Upon binding to their receptor on the cell surface, these hormones activate intracellular signaling pathways that use second messengers like cAMP or Ca2+ to propagate the signal and elicit a cellular response.
