What else can I help you with?
What type of drug is Lexapro?
No, it is an SNRI. SNRIs act to both serotonin and norepinephrine whilst SSRIs only to serotonin. Venlafaxine (Effexor) is thought to be stronger than SSRIs but may have more side effects due to its double action. In doses over 225mg, it has some moderate action to dopamine.
What proteins have a shape that allows only a specific molecule to bind to it?
Proteins that have a specific shape allowing only certain molecules to bind are known as "receptor proteins" or "enzymes." These proteins possess unique active sites or binding sites that are complementary in shape to the specific substrate or ligand they interact with, often described by the "lock and key" or "induced fit" models. This specificity is crucial for biological processes, as it enables precise interactions between molecules, such as hormone-receptor binding or enzyme-substrate catalysis. Examples include insulin receptors and enzymes like amylase.
Why does a virus only attach to only one cell?
A virus attaches to a specific cell because it has proteins on its surface that can only bind to receptors on that specific cell. This binding is necessary for the virus to enter the cell and replicate. This specificity is determined by the structure of the virus and the receptors on the cell surface.
How do hormones establish selectivity quizlet?
Hormones establish selectivity by binding to specific receptors on target cells, which are uniquely equipped to recognize and respond to particular hormones. This binding triggers a series of biochemical reactions that lead to specific physiological responses. The presence of these receptors ensures that only certain cells respond to a hormone, allowing for precise regulation of bodily functions. Additionally, the concentration of hormones and the abundance of their receptors can further influence the selectivity and intensity of the response.
What molecules determine the tissue specificity of hormones?
The tissue specificity of hormones is determined by the presence of specific hormone receptors on the surface of target cells. These receptors are proteins that can only bind to specific hormones, allowing for a precise response in a particular tissue. The binding of a hormone to its receptor triggers a specific signaling pathway that leads to the cellular response.
Does atropine block only nicotinic receptors?
Atropine does not only block nicotinic receptors but also acetylcholine at muscarinic receptors
How do psychedelic mushrooms affect a menstruating woman?
This strongly depends on the individual concerned. It only affects perception. This may cause any mood possible, since psilocybin constantly attaches to many of the serotonin receptors inside the brain.
Mix hydrocodone and SSRI?
It is perfectly safe to take Selective Serotonin Re-uptake Inhibitors with hydrocodone. They do not interact or effect one another. SSRI's only affect the serotonin levels in your brain, hydrocodone blocks nerve receptors, which helps with pain. So any SSRI anti-depressant is safe to take with hydrocodone. Edit: I wouldn't say it is perfectly safe. Serotonin Syndrome can happen and isn't something you just brush off
What is the difference between an allosteric enzyme and a non-allosteric enzyme?
An allosteric enzyme has multiple binding sites that can be used to modulate its activity through the binding of effectors or ligands, whereas a non-allosteric enzyme typically only has one active site. Allosteric enzymes can exhibit cooperativity, meaning that binding at one site affects binding at another site, while non-allosteric enzymes do not show this behavior.
Is serotonin a catecholamine?
no serotonin is not a catecholamine. Catecholamines are dopamine, epinepherine and norepinepherine.
What does Monotopic mean?
Monotopic refers to a protein or enzyme that has only one binding site for a ligand or substrate. It means that the molecule can only bind to one specific site on the protein, as opposed to proteins with multiple binding sites which are known as polytopic.
How does lexapro and Wellbutrin work together?
My psychiatrist prescribed both at once.AnswerNo they should not be taken together why not?Cymbalta and Lexapro have SIMILAR BUT NOT EXACTLY THE SAME mechanism of action [MEANING: these active ingredients illicit the same response and the enzymes attach to the same receptors (receivers) that prevents the serotinin from leaving the brain]. Cymbalta is an SNRI (Serotonin-Norepinephrine Reuptake Inhibitor) and Lexapro an SSRI (Selective-Serotonin Reuptake Inhibitor). Serotonin is "BELIEVED" (not certain) to lack from people who are clinically depressed and norepi has "significant" correlation with depression as well (LOW NOREPI in the brain results to DEPRESSION). Cymbalta and Lexapro both have positive responses in preventing the escape of SEROTONIN from the brain. The only difference is Cymbalta also inhibits/stops the escape of norepi from the brain and Lexapro ONLY prevents serotonin reuptake (removal from brain receptors). The probability of an overdose from these antidepressants is extremely high and can lead to 'serotonin syndrome; too much serotonin which can be fatal (nausea,coma then death). Because both drugs are preventing serotonin from leaving the brain and therefore an accumulation of serotonin in the brain receptors. Only your MD can determin the OPTIMUM strength (the highest strength of the meds. to achieve therapeutic goals without being toxic) of antidepressants. ALSO, if your MD can justify why he's giving you both meds to the insurance, it will be covered by insurance. This will definitely be reviewed prior to approval of claim. These types of drug interactions alerts your insurance and stops them from paying the claim. You may end up paying for either or both your meds out of pocket.
