How can one hormone molecule lead to the synthesis of thousands of enzyme molecules?
The mechanism through which a single hormone molecule triggers the generation of thousands to millions of enzyme molecules is called biological signal transduction
This process begins with a hormone molecule binding to its receptor on the surface of a cell. Following this, there is a signal generated.Inmolecular Biology, asignal is said to be generated when a certain inter-cellular or membrane-bound protein becomes phosphorylated and triggers further downstream events.
The ultimate result (or the end step) ofthis signal transduction pathwayis to up-regulate thetranscription of a specific enzyme-coding gene. When many copies of thisgene are transcribed,several molecules of the enzymeswill be produces.
What else can I help you with?
What hormone decreases protein synthesis increase fatty acid release and stimulates glucose synthesis?
The hormone that fits this description is cortisol. Cortisol is a stress hormone that promotes the breakdown of proteins into amino acids to increase fatty acid release and stimulate gluconeogenesis (glucose synthesis) in the liver.
What is a molecule such as a neurotransmitter or a hormone that binds to a receptor called?
A molecule such as a neurotransmitter or hormone that binds to a receptor is called a ligand. This binding triggers a biological response in the target cell, influencing its function.
Which substances are found on cell surfaces and respond to nerve and hormone signals?
Receptors, such as neurotransmitter receptors and hormone receptors, are found on cell surfaces. These receptors bind to specific signaling molecules like neurotransmitters and hormones, allowing cells to respond to these signals and initiate a biological response.
Which of the choices below is not a factor required for target cell activation by hormone receptor interaction?
Protein synthesis is not a factor required for target cell activation by hormone receptor interaction. The essential factors include binding of the hormone to its receptor, conformational changes in the receptor, and activation of intracellular signaling pathways.
What Messenger molecule carries instructions from its host organ to other cells in the body is known as a?
chromosomes
What is a mechanism by which a single hormone molecule can trigger the production of millions of molecules of a metabolic product?
enzyme
Which hormone influences the rate of protein synthesis of skeletal muscles?
Growth hormone (GH)
What hormone decreases protein synthesis increase fatty acid release and stimulates glucose synthesis?
The hormone that fits this description is cortisol. Cortisol is a stress hormone that promotes the breakdown of proteins into amino acids to increase fatty acid release and stimulate gluconeogenesis (glucose synthesis) in the liver.
What hormones increase protein synthesis?
Growth hormone
IS FAT A HORMONE OR ENZYME?
No it is not a hormone or an enzyme. It is a type of molecules
What is the hormone that regulates the synthesis of HCl in the stomach called?
gastrin
What must be available for Thyroxine to be synthesized?
Thyroxine is synthesized in the body from tyrosine, an amino acid. In order for thyroxine synthesis to occur, iodine must also be available as it is a key component of the molecule. Additionally, enzymes such as thyroid peroxidase and thyroglobulin are needed for the synthesis process to take place.
A colony of bacteria growing on a culture medium is successfully synthesizing an organic compound Which procedure would be least likely to have an effect on this synthesis?
increasing the number of hormone molecules in a colony
What kind of molecules are wax and testosterone?
hydrophobic molecules. Testosterone is a hormone made of sterol.
Is insulin a steroid hormone?
Insulin is an anabolic hormone as: 1) it promotes glycogen synthesis & inhibits glycogenolysis and gluconeogenesis in carbohydrates. 2) it promotes lipogenesis & inhibits lipolysis. 3) promotes protein synthesis & inhibits protein degradation
Iodine is essential for the synthesis of what hormones?
TSH (thyroid stimulation hormone) Iodine is necessary for the thyroid gland to make thyroxin hormone. ( T3 and T4)
What is a creation of a hormone called?
The production of a hormone is called hormone synthesis or hormone biosynthesis. It typically occurs in specialized cells or glands within the body. Hormones play important regulatory roles in various physiological processes.
