Gonadotropins are hormones synthesized and released by the anterior pituitary gland, which act on the testes and ovaries to increase the production of sex hormones and stimulate production of either sperm or ova. The hypothalamus contains Gonadotropin-releasing hormone (GnRH). Intermittent released of GnRH is responsible for the biosynthesis and secretion of ...

As you point out, these are all quaternary ammonium compounds that are likely to work in a similar way (membrane disruption) and are very broad spectrum. Any differences in efficacy against a given pathogen would need to be established by empirical testing on that particular organism, as these kind of things are highly idiosyncratic--it's not like an enzyme ...

Short answer It all depends on how you look at $k_\text{cat}$ and enzyme concentrations Long answer The effect of an uncompetitive inhibitor on $k_\text{cat}$ can be interpreted in two ways. Interpretation 1: This is followed in the lecture series mentioned in the question. See the video https://youtu.be/rNBEUGYu034 from 7:37 to 11:01 minutes. The ...

As a notation note, I never seen your $P_a{O_2}$ notation used except for referring to arterial partial pressure ($P_v{O_2}$ would be venous). Generically, partial pressures are usually noted as, for example, $P_{O_2}$. When we talk about partial pressures in biology, we literally mean the partial pressures: that caused by dissolved gas. Hemoglobin-bound ...

Yes! Many mammals, including cats and humans, produce DMT in small amounts. DMT has been detected in blood and urine and is produced by the enzyme indolethylamine N‐methyltransferase (INMT). These do bind to serotonin receptors. Serotonin receptors are actually expressed in multiple tissues outside of the brain. However, DMT does cross the blood-brain ...

I will focus on the meaning of ‘activated carrier molecule’ as descriptions of enzymes abound. In order to do that I need to introduce two other ideas first. I apologize to the purists for tailoring this to the level of the question. 1. Gibbs Free Energy in Biochemical Considerations There are different ways of considering energy, and in chemistry one may be ...
