. why do you think four molecules of catecholamine neurotransmitters are generally bound to each molecule of atp?

Answers

In four neurotransmitter molecules the catecholamine is bound to each molecule of ATP because the synaptic vesicles and synaptic granules on the neurotransmitter contain adenosine triphosphate with a molar ratio of catecholamine to ATP of approximately 4:1.

Hormones that play a role in the nervous system are catecholamines in the form of epinephrine (adrenaline) and norepinephrine (noradrenaline). The adrenal medulla contains chromaffin granules (organelles in cells) which function for the biosynthesis, absorption, storage, and secretion of catecholamines.

Other compounds contained in these granules are ATPMg2+, Ca2+, Dopamine-β-hydroxylase (DBH), and the protein chromogranin. Catecholamines enter the granules by a transport mechanism with an ATP-dependent ratio of catecholamines : ATP = 4 : 1. Norepinephrine is stored in the granules, can leave and undergo methylation of the N-terminal end of the protein to form norepinephrine and then enter new granules.

here. We have been given an example that a person is eating the breakfast and then going for Redden. Now, according to this example, we have to answer a few questions. Yeah. The first question is asking us to give up chemical equation to explain the energetic process which is going on in the example given to us. So the chemical equation here which would act is C 12 H 22 0 11, that's the same amount of water. They don't give C6 H 1246 less C six H 12 or six and some amount of heat. This is the chemical equation for the example which is given to us Now, talking about the second question, it is asking us that in the given example we have to define a situation where potential energy plays its role. So potential energy defines director energy which is really stalled. So yes, we can see that the food which is eaten by that person gets converted into You can meet them energy with the help of chemicals which act on that fourth during the process of fertilization. Now, after the process of decision is completed, this food gets stored in our body and this food after the completion of the whole process this storage results into the for 10 Children energy and these books can then withdraw as the potential energy of the body. Next We have been asked that in the given example where is the kinetic energy which has been acted. So we know that kinetic energy is the energy which applies on any kind of movement. So here we have been given that after eating the breakfast, that person went for the running this johnny is the process off utilizing this toad potential energy and converting it into kinetic energy. This was an option for the 3rd point of the question. Now, both part of the question is asking us that this example is related to the first love of there's more dynamics. So we know that in the first law of thermodynamics, this stated to us that the total N. L. G. Of any kind of work of the whole universe, we can say that its total energy the means constant. So here or two, we can see that the chemical energy which was produced by the digitization of wood, these converted into potential energy due to the storage of food and its nutrient in our body. Then these potential energy. What we didn't do kinetic energy patterns, the person went for johnny and the movement of body took place which resulted in kinetic energy. So the energy which was being provided to that person remained constant and it just moved around with the different me and in the different processes. But that energy is going nowhere else that it is not being either destroyed or new energy is not produced. They are just being Moving from one place to another. And the last question is asking us that how this example is good for second law of there are more dynamics. So second law of thermodynamics says that its main concern is regarding the direction of natural processes are natural movement. It assists that the natural processes which are occurring. They are moving in one particular direction, and they are not diverged. Seven. So here also we can see that the energy God confided from chemical to potential, and then to the kinetic energy. In other words, we can say that the food which was eaten what converted our court digested and then it was utilized for Ronnie. And he is the reversal that is after running the food again, getting back to its duty version stomach. This process does not take place. So we can say that there is only a one way direction of this movement of energy and there is no diversity employees is project. It only gets renewed in tisa marty, a death process.

What makes up the inside or the steps of a DNA molecule?

Answers

Answer:

The sides of the backbone of DNA are made up of alternating sugar (deoxyribose) and phosphate groups. The inside of the DNA molecule, or the "steps" as you put it, consists of the bases: adenine, guanine, cytosine, and thymine. These bases pair up with each other in specific ways: adenine always pairs with thymine, and guanine always pairs with cytosine. This is what gives DNA its unique double-helical structure and allows it to store genetic information.

Answer:

The backbone of a DNA molecule consists of the phosphate groups and the deoxyribose sugars, whereas the base of the DNA molecule consists of nitrogenous bases, therefore, the backbone of DNA is made up of phosphate groups and pentose sugars. Adenine is a part of the base of the molecule.

You've got to take those letters and make them into words, and those words into sentences, and those sentences into concepts, and the more you do that, the more vivid your imagination becomes. And, I believe that's probably one of the reasons that you see that creative people tend to be readers, because they're exercising their mind.I was reading about people in laboratories, pouring chemicals from a beaker into a flask and watching the steam rise, and completing electrical circuits, and discovering galaxies, and looking at microcosms in the microscope, and I just acquired so much knowledge, and I had put myself into those settings and I saw myself differently than everybody else in my environment who just wanted to get out of school so they could get some cool clothes and a cool car. And, I was looking down the pike and seeing myself as a scientist or a physician or something of that nature, and that was one of the things that sort of carried me through much of the ridicule and some of the hardships that a person would have to go through coming from my environment and going to medical school.The thing that I am probably the most proud of is not all the medical accomplishments or honorary degrees or various boards and societies. I'm most proud of the 100,000-plus letters that I have from young people, throughout America and around the world, whose lives have been changed by reading one of my books, or seeing me on television, or an interview in a magazine, and recognizing that they have the ability to define their own lives. If that's the legacy that I leave, I'll be very happy.I was talking to a friend of mine, who was a cardiothoracic surgeon, who was the chief of the division, and I said, "You guys operate on the heart in babies, how do you keep them from exsanguinating" and he says, "Well, we put them in hypothermic arrest." I said, "Is there any reason thatif we were doing a set of Siamese twins that were joined at the headthat we couldn't put them into hypothermic arrest, at the appropriate time, when we're likely to lose a lot of blood?" and he said, "No." I said, "Wow, this is great." Then I said, "Why am I putting my time into this? I'm not going to see any Siamese twins." So I kind of forgot about it, and lo and behold, two months later, along came these doctors from Germany, presenting this case of Siamese twins. And, I was asked for my opinion, and I then began to explain the techniques that should be used, and how we would incorporate hypothermic arrest, and everybody said "Wow! That sounds like it might work." And, my colleagues and I, a few of us went over to Germany. We looked at the twins. We actually put in scalp expanders, and five months later we brought them over and did the operation, and lo and behold, it worked. ere is a hypothetical mrna sequence: 5' g a u g c g u a a a u a g 3' what is the amino acid sequence encoded by this mrna?
