An enzymatic reaction (e+s2 es> p +e) obeys michaelis-menten kinetics and gave the following 4. kinetic results: k1 = 1.0 × 108 m-1 s-1, k-1 = 1.0 × 103 s-1, k2 = 1.0 × 104 s-1 e1-e+est-1.0 x10-6m a. what is the dissociation en b. what is km for the enzyme? c. what is the turnover number (kcat) for the enzyme? d. what is the catalytic efficiency (kak? e. what is a typical value of a bimolecular diffusion limited rate constant and how does it compare with constant (k-61) for the enzyme-substrate complex? [ejis [es f. what is the value of vmax? g. what concentration of substrate would give a reaction velocity (v) equal to 0.75*vmax? h. if the initial substrate concentration ([slo) is equal to 10.0 mm and initial product concentration is zero, how long will it take to form a product concentration of 4.0 mm? state any assumptions. if the initial substrate concentration is reduced to 10.0 nm and initial product concentration is zero, how long will it take to form 4.0 nm product? state any assumptions. i.

Ionic compounds are made of ions, and yet the overall charge of an ionic compound is neutral. why?

Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. one potential application of nanotechnology is the construction of artificial cells. the simplest cells would probably mimic red blood cells, the body's oxygen transporters. for example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person's bloodstream. if the person needed additional oxygen-due to a heart attack perhaps, or for the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. suppose that the nanocontainers were cubic and had an edge length of 24 nanometers. part a part complete what is the volume of one nanocontainer? (ignore the thickness of the nanocontainer's wall.) express your answer using two significant figures. v v = 1.4ă—10â’20 l previous answers correct significant figures feedback: your answer 1.3824â‹…10â’20 = 1.382ă—10â’20 l was either rounded differently or used a different number of significant figures than required for this part. if you need this result for any later calculation in this item, keep all the digits and round as the final step before submitting your answer. part b suppose that each nanocontainer could contain pure oxygen pressurized to a density of 81 g/l . how many grams of oxygen could be contained by each nanocontainer?

A4.86 g piece of metal was placed in a graduated cylinder containing 15.5 ml of water. the water level rose to 17.3 ml. what is the density of the metal. i need the steps of how to solve it to so i can use a formula to work out other problems.
