How to find kcat |

|
|
Silica gel as stationary phase -- which compounds will elude first? |
Silica gel = POLAR Non polar items will elude first (the fastest) and the most polar will elude the slowest |
|
|
Silica gel is polar or nonpolar |
POLAR -nonpolar eludes first |
|
|
Half life of a radioactive material is: |
The time it takes for half of all the radioactive nuclei to decay into their daughter nuclei (which may or may NOT be radioactive) |
|
|
To keep body in EQ while rising -Person is in EQ only wen center of mass is directly above their feet. Otherwise if person did not lean forward, the person would fall back due to large torque created by combo weight and body applied to center of mass |
|
|
What is type I an type II error |
|
|
|
Wavelengths that represent molecules that exhibit an electron excited states that is closer in energy to the ground state |
Larger wavelengths = lower energy. These will have excited states that are lower in energy, and closer to ground state since less energy is needed for it to go to higher n (Energy of a photon matches the energy gap b/w the ground and the excited state) |
|
|
Which property of a substance is best used to estimate its relative vapor pressure |
Boiling point (when compared to melting point, molecular weight, dipole moment) |
|
|
What are the structural features possessed by storage lipids? |
Three fatty acids ester linked to a single glycerol (neutral) |
|
|
Role of catalyst |
Increases the mount of product produced per unit TIME |
|
|
Equation to find pH |
|
|
|
How many electrons in a charge (C)? |
Coulombs / charge = # of electrons |
|
|
How to find electrons from charge |
|
|
|
Hess's law |
|
|
How much vol of N2 gas would be produced at STP from 1 mol of nitrglyc? |
1 mole of nitroglyc produces 1.5 moles of N2. At STP 1 mole = 22.4 L. So there would be (more) roughly 30L of N2 at STP

|
Image for diverging lens |
All images are virtual, upright, and reduced |
|
|
What type of energy is a battery |
CHEMICAL not electrical energy |
|
|
What is the conversion of energies that tales place in a battery powered resistive circuit when the current is flowing? |
Chemical -> electric -> thermal |
|
|
Protein secondary structure is characterized by the pattern of hydrogen bonds between |
Backbone amide protons and carbonyl oxygens |
|
Which of these steps require ATP binding/hydrolysis |
I. Dissociation of myosin head form actin filament (ATP BINDING) III. Conformational change that moves actin and myosin filaments relative to one another (Need ATP to be hydrolyzed) VI. Reuptake of calcium into sarcoplasm (Calcium against gradient so needs ATP) |
