Chemistry Review Flashcards
Formula for Density
p=m/v (kg/m^3 or g/mL)
Equation for Mechanical Work
work = Fdcos(θ)
What is theta when linear deformation is present?
0 degrees
Which choice has the longest wavelength?
a. x-rays
b. UV light
c. Red light
d. Blue light
e. Radio waves
e. Radio waves
Wavelength increases from left to right on the electromagnetic spectrum
a < b < d < c < e
What is the definition and equation for Power?
Work divided by time
W/t in watts
Can also be P=Fv (constant)
Why does surface tension decrease as temperature rises?
As the average kinetic energy of fluid molecules increases, they are more likely to overcome the intermolecular forces holding them together.
In which direction do positive flow through voltage gradients?
Down the gradient from high to low voltage.
In competitive inhibition, how are Km and Vmax affected?
Km is increased since more substrate will be required, but Vmax stays the same as long as enough substrate is present.
In noncompetitive inhibition, how are Vmax and Km affected?
Vmax and Km both decrease proportionately
Where does the inhibitor bind in noncompetitive inhibition?
The allosteric site. (Does not compete with the substrate)
What is the slope of Lineweaver-Burk plots in uncompetitive inhibition?
Km/Vmax
Are negatively charged ions hydrophilic or hydrophobic?
They are hydrophilic
