Chymotrypsin serves as a catalyst in the "Hydrolysis" of pepdite bonds - found in carboxylic groups of amino acids, which consist of aromatic pedand groups and large hydrophobic groups. Chymotrypsin is also known to serve as a catalyst in the Hydrolysis of "ester - and amide bonds" , found in hydrophobic groups. 1. Would you expect the KM of the reactions of Chymotrypsin with the different substrates to have the same value ? explain. 2. Would you expect the Vmax of the reactions of Chymotrypsin with the different substrates to have the same value ? explain. 3. Would you expect the " pH-dependence " of the "hydrolysis - reactions" of the different substrates to be the same…

how do we polarize any wave?

Ok, so i'm doing a lab right now to see how the amounts of sugar affect yeast activity. We have equal amounts of water and yeast in 5 test tubes. Each of the 5 test tubes get diff amounts of sugar: one with no sugar, one with 1 g, and another with 2 g, and another with 4 g, and the last one having 8 g. I understand that the yeast in the tubes with sugar went thru cellular resp so that's why it gave off co2. But the one with no sugar still produced 21 mm of bubbles. Why did that happen? Isn't it impossible to go thru cellular resp without glucose? Did it produce co2/o2 in another way? Also, we used sink water instead of distilled water so i'm not sure if that matters or no…

I have been a little confused by this recently When are surfaces 2D and when they higher dimensional? I understand hypersurfaces can be of any number of dimensions so long as they have one less dimension than the space they are embedded in. But are there also 2D surfaces embedded in these higher dimensional spaces? And how does this apply to 3D+1 space-time?

Mid brain is responsible for the sense of right-handedness. But what about the mid brain of Ambidextrous persons and left-handed persons?

Hello, I have this signal in the picture and I need to turn it into frequency . How can I do this please I have no idea where to begin with . It's the second convo in the picture.

can somebody please help me with below question? It is urgent homework help. much appreciated In your own words, explain what is meant by dynamic programming. Give an example of a problem for which this would be a useful approach, and describe briefly how dynamic programming would solve this problem. You should aim to write 1/2-1 page

1) Neurons propagate signals in the form of action potentials that are mediated by: a.- Na + channels regulated by voltage that open in response to membrane depolarization b.- K + channels regulated by voltage coupled to neurotransmitters c.- Ca ++ channels that connect electrical signals to chemical d.- Chlorine channels regulated by voltage My possible answer for this one is b or d. What I read was very confusing 2) Which of these molecules do not intervene in the Krebs cycle: a.- Acetyl CoA B.- Pyruvate c.- FAD d.- NAD my possible answer on this one is pyuvate because thats the result of the glycolysis 3) It i…

Okay, so, instead of a test style midterm for Science 10 (general sciences) we're making a science fair project. I have no idea what I should do. I was looking into building something but I don't know what. Does anyone have any ideas or suggestions?

Good day, I was asked to plan and design an experience to solve this problem: one student accidentally poured excess sodium hydroxide in to a container that contained ethanoic acid. Plan and design and experience to separate them. Please help me

Not homework as such but I would appreciate feedback as to whether I am making progress into understanding the main principles of this theory Can I take Special Relativity as setting the stage with a "clean sheet" of flat spacetime? As I see it the main understanding in GR is that ,in a spacetime populated by massive objects at every point it is possible to find 3 2D surfaces corresponding to each spacial dimension plus the time dimension As one finds each of the 3 curvatures on these 3 surfaces (caused by the presence of nearby massive bodies or energetic effects) this overall curvature will allow one to draw a geodesic at any point which will in…

Okay, before you go "this topic already exists" on me- I'm in a rush (my username) and don't really have the time. If someone's good with chemistry (nothing advanced) I really need some help so I can understand some of this for an exam. One of exam questions I just can't do is: Find the formula of a crystalohydrate FeSO4 that contains 6.3 grams of H20?

Qs: If it takes 24 days for 75% of an isotope to undergo a first order decay reaction what is the half-life for the isotope? I understand half-lives, however, I'm just not sure what the question is asking for me to solve. I thought it meant that 75% of an element (that happened to be an isotope of an element) took 24 days to decay by 75%, meaning 25% was still left. So I thought I would figure out the original amount of time it took at that rate, which would be 32 days. Then I halved that (because it is the half life of it) and got 16 days, however, that is not an answer choice. I don't know if there is a formula to solve this, but this has got me quite confuse…

Hello everyone. I have been steadily reading through a book on human physiology and I have come across a problem related to the Goldman Equation that I am trying to understand, which is the following: Because of the fact that we are working with a chloride-free medium, chloride ions are ignored from the Goldman Equation which gives the following: Where E is the membrane potential, RT/F is a constant that is equal to 26.7 at 37 degrees Celsius, P with respective subscripts represent coefficients of different ions, and the ions in square brackets are the concentrations in mmol/L. Subscripts "o" and "i" represent extracellular and intracellular concentrations…

Hey folks, I'm writing this thread as per my nephew's high school project. He needs to create a proposal for manufacturing computer keyboards. At this point, he needs to find out how much the primary components of a conventional computer keyboard costs (for a company such as Logitech). I was able to find some DIY websites, but I believe the prices quoted were a bit skewed as they are not meant for mass production. I'm not sure who else to approach. Perhaps refurbishing companies? Can someone please make a suggestion? TIA, grecinos

its catalase +, oxidase +, ferments glucose and produces gas from the process, and is a gram + facultative anaerobe and its highly resistant to antibiotics and motile + and has been seen to grow up to temps of 103°F, colonies are white and turn slightly yellowish, orange after 2-3 days, small punctiform colonies. Colony elevation is raised. Colony margin varies from complete to irregular, odor is pungent and has an odor of ammonia after several days

E.g. y'(x) + ay(x) = f(x) where a is a constant. I know we basically get exp(ax), then equation becomes [exp(ax)y(x)]' = exp(ax)f(x). But since f(x) is abstract/not defined, I don't know how I would not get stuck with a recursive integral on RHS after trying to integrate. Anyone know how to evaluate integral of exp(ax)f(x)?

A person with a concave lens of power -5D has his far point at 20 cm and his near point at 25 cm. How is it possible?

https://imgur.com/a/ESsNm I have a rough idea on how to solve the second one, but I don't know if my method is correct. I used the shell method with the value (y+3) for the radius. But I have no clue how to solve the first question. https://imgur.com/a/zJdFw

Hello, I'm new here and also new to Computer Sciences. I'm a first semester university student and so far we're only doing mathematics and a lot of theoretical background on computer sciences. So in one of my assignments we have the option for 120 bonus points but it's pretty much exclusive to those who have programmed before and I find this quite unfair. We complained, so at least one of our tutors helped us in recommending some code snippets. But since I have never coded before I'm totally lost and I really would want to have at least a part of those bonus points. The question is: "Calculate the Ackermann Function A for A(8,6). Write d…

Hello! I have some problems with constructing Lagrangian for the system (attached files). I made an attempt to find the Lagrangian (attached files), but I'm not sure if I did everything correctly. I also didn't use l, that is given in the conditions, to construct Lagrangian. Please help me point out my mistakes. I'll appreciate any help.
