How does the sodium-potassium pump get the energy to pump ions?
ATP is used to generate the energy to pump with 3 Na+ Out, 2 K+ in. Can be remembered by mnemonic 3-2 NOKIA.
Given f(x) = x^3 + 3x^2 + 5, find f'(1).
This is a derivative, so f'(x) = 3x^2 + 6x. Thus, f'(1) = 3*1 + 6*1 = 9
If you flip a coin 5 times, what is the probability you will get 5 heads?
(1/2)^5 = 1/32. Since each coin flip is an independent event, we can multiply the probability of getting heads for each event 5 times, which is 1/2^5
