Molarity calculations
Solution of 500mL and 25g of a 50g/mole compound
1 M
pH when [H]+ is (1 x 10^-7)
7
define enthalpy
heat of a system
the 4 categories of macromolecules
protein, carbs, nucleic acids, and lipids
main component of cell walls
phospholipids
Solution of 327mL and 56mg of a 342g/mole compound (answer in uM)
500uM
pOH when pH is 8.9
5.1
define entropy
disorder
name for process of creating new peptide bonds
condensation reaction
Define active transport
movement of molecules which requires energy
Grams of a compound (37g/mole) added to 500mL solution to make 50mM concentration
0.925g
pOH when [H]+ is (2.7 x 10^-4)
10.43
define a spontaneous reaction
has a negative change in free energy
lipid storage in cells
lipids are stored in triglycerides
The main way human cells obtain energy in the form of ATP
glycolysis and oxidative phosphorylation
micrograms of a compound (127g/mole) added to 125mL of solution for a concentration of 27uM
428.6ug
pH when [OH]- is (4.5 x 10^-2)
12.65
Why spontaneous reactions do not constantly occur on their own
Because of activation energy
functional groups of an amino acid
carboxylic acid, amine
glucose is broken down into 2 of these during glycolysis
pyruvate
Molecular weight of a compound X. 200mg of this compound on 430mL of water create a solution of concentration 12mM.
38.76g/mole
[OH]- when pH is 2.4
2.5 x10^-12
the first two laws of thermodynamics
1. Energy cannot be created or destroyed
2. Disorder tends to increase
parts of a phospholipid
hydrophobic tail, glyceride, hydrophilic head
where the pH is lowest in the cell
the intermembrane space of the mitochondria
