What is the energy of a single photon of yellow light with wavelength 685 nm? Express your answer in calories using scientific notation to 3 significant figures. For example, Planck's constant would be typed in like this: 1.58e-34 NOTE: If you type in the correct number, Canvas will show 0 in the answer bar instead of the proper number. That's one of the shortcomings of Canvas. But, if you typed in the right number, then Canvas will mark it correct, so don't panic.

For a particular reaction, AH° = −16.1 kJ/mol and AS° = −21.8 J/(mol·K). Assuming these values change very little with temperature, at what temperature does the reaction change from nonspontaneous to spontaneous in the forward direction?

A flat (not spherical) tissue engineered skin (thickness 3.9 mm) is attached to the bottom of a dish and cultured with cell media atop it (which has an oxygen concentration of 0.15 mol/m3). The diffusivity of oxygen in the skin is 3.2 E-9 m?/s, and according to experiments that you've performed, you want to make sure that the concentration of oxygen in the device doesn't fall below 0.06 mol/m3. (Below that concentration harms the cells.) The rate of oxygen consumption is -5 E-17 mol/[cell•s]. What is the maximum cellularity (in cells/mL, three significant digits) that this tissue engineered skin can support?

How far will the electron have traveled in this period of time? (b) Make the same calculations for a 1.00-g insect whose speed is the same. What do these sets of figures indicate?
Paper electrophoresis of Asn, Ala, Asp, Lys and Ser mixtures at pH = 7 shows the fastest movement towards the anode The fully saponified 10g oil sample consumed 1.87g KOH, and the iodine value of the oil was 28.3. So how many unsaturated double bonds are there in each oil molecule on average? (lodine is known to have an atomic weight of 127) Given that 100g cellulose sample is completely hydrolyzed to obtain 78g glucose, then the percentage of cellulose in the sample is _% Given that the Km of catalase is 20mmol/L and the substrate concentration is 80mmol/L, then the percentage of catalase bound to the substrate is %
A research group discovers a new version of happyase, which they call happyase*, that catalyzes the chemical reaction: HAPPY-SAD The researchers begin to characterize the enzyme. The researchers determined the kcat of the enzyme to be 452 s-1. In a separate experiment with [E;) at 1.5 nM and [HAPPY) at 38 µM, the researchers find that Vo is equal to 320 nM s-1. What is the measured Km of happyase* for its substrate HAPPY? Make sure to include units in the answer.
What if all the data above was the same EXCEPT with the change of G & X? Their new data is below. Would base X still be T? G & X [G] = 0.0447315M [X] = 0.0447315M [GX] = 0.0026845M 1.3416
You have an initial solution in which you added quantities of “A” and “B” such that there is 4.5 M “A” and 2.5 M “B” and no complex (“AB”) at time 0. After equilibrium, you are able to isolate and quantitate the “AB” complex, and find its concentration is 1.5 M. Given that RT is 0.59 kcal/mol, what is the delta Go’ for the association reaction?
Answer the following questions yes or no (Y/N): Is the michaelis-menten equation valid under experimental conditions? Is the michaelis-menten equation only valid for reactions that are at equilibrium? Is extrapolation to Vm inaccurate, but Km is accurately determined in the michaelis-menten equation? Is the michaelis-menten equation nonlinear? Is extrapolation to Vm inaccurate, and therefore Km cannot be accurately determined in the michaelis-menten equation?
