Neurotransmitter binding are designed to be brief so that another one can be initiated if needed. Failure to break down neurotransmitters so that a signal is always activated can be disasterous to a biological organism. In fact, nerve gases, (e.g. sarin) work by inhibiting the enzyme cholinesterase, which breaks down acetylcholine in autonomic nerve synapses and neuromuscular junctions.

What is the function of carrier?
Carrier proteins are the transporters of active transport. They are stereohemically conformed in such a way as to facilitate the movement of specific chemicals across celll membrances. Each carrier protein is designed to recognize only one substance or one group of very similar substances. The molecule or ion to be transported (the substrate) must first bind at a binding site at the carrier molecule, with a certain binding affinity. Following binding, and while the binding site is facing, say, outwards, the carrier will capture or occlude (take in and retain) the substrate within its molecular structure and cause an internal translocation, so that it now faces the other side of the membrane. The substrate is finally released at that site, according to its binding affinity there. All steps are reversible. For example: Diffusion of sugars, amino acids,nucleoside. Uptake of glucose Transportation of salts, glucose, and amino acids
True or False Low Km means that an enzyme binds very loosely to a substrate andd consequently results in a high velocity compared to an enzyme with a high Km?
False. Low Km actually indicates a strong binding of the enzyme to the substrate, resulting in a high affinity and low velocity at low substrate concentrations. High Km means a weak binding of the enzyme to the substrate and requires higher substrate concentrations for the enzyme to achieve maximum velocity.
How do hormones affect the activities of other cells?
Hormones are chemical messengers secreted into blood or extracellular fluid by one cell that affect the functioning of other cells. In very basic terms, binding of hormone to receptor triggers a cascade of reactions within the cell that affects function. I Have Placed A Likn In My Bio That You Can Check Out!!
What types of neurotransmitters do antidepressants target?
There are three very important neurotransmitters in the brain that antidepressant medications focus on. Firstly, let me briefly review antidepressant medications. Antidepressants are medications that work by increasing the amounts of chemicals or neuro-transmitters in the brain. A very common antidepressant of today is known as Prozac or Fluoxetine (the trade name). Prozac works by increasing levels of serotonin in the brain.Now, the three neurotransmitters in the brain are:1.) Serotonin2.) Norepinephrine3.) DopamineAll three of these chemicals have some influence on depression. As a result, medications have been designed to work on increasing the above neurotransmitters. For example, Prozac works on serotonin and Cymbolta works on both serotonin and norepinephrine. Serotonin is the most researched neurotransmitter so far, but research is looking into how norepinephine and dopamine also influence depression. Another neurotransmitter in the brain that has an influence over depression is aceytlcholine.
What are the effects of removing stomach both effects on lifestyle and digestion?
Removing the stomach (total gastrectomy) results in significant changes to both lifestyle and digestion. Lifestyle effects include strict dietary modifications, smaller and more frequent meals, and lifelong nutrient supplementation. Digestion is impacted as the stomach plays a key role in food storage, digestion, and absorption, so without it, digestion is altered, leading to potential complications such as malabsorption and dumping syndrome.
What causes the synaptic delay?
The cause of synaptic delay is attributed mainly to the time needed for the synaptic vesicles to release neurotransmitter into the synaptic cleft. While it can be considered a combination of binding to the presynaptic membrane (which is relatively a transient process) and subsequent exocytosis of the neurotransmitter, the main factor is release. Additionally, it does take a very short period of time for the neurotransmitter to diffuse across the synaptic cleft and bind to to its receptors on the post-synaptic membrane.
