biochemisty Flashcards
Hydrophobic
Water resistant
Hydrophilic
Water spreads more, “H2O loving”
Cohesion
Attraction of H2O to H2O
Adhesion
Attraction of H2O to something else
Why is there a hill when there is water and oil on a sheet?
Oil and water mixing = cohesion of h2o being greater than force of adhesion with water and oil molecules
How many amino acids does a complete protein have
20 amino acids
What does incomplete protein miss?
Essential a-a
What do vegans have to do to make an incomplete protein complete?
Pair with whole grain to make it complete
Hydrolysis
Using H2O to break apart something
Hypotonic
State an example and what happens to the solute concentration and H2O concentration
Ex. Fresh/tap water
Decrease solute concentration, increase water concentration
H2O moves into cell
Isotonic
State an example and what happens to the solute concentration and H2O concentration
Ex. Physiological Saline
H2O and solute are the same
Equal parts move in and out
no net movement
Hypertonic Solution
State an example and what happens to the solute concentration and H2O concentration
Increase solute concentration, decrease H2O concentration
H2O moves out of the cell
Turgor Pressure
High and Low
High turgor pressure, large vacuole = turgid hard cells
Low turgor pressure, small vacuole = flaccid soft cells
What is the difference between plant and animal cells
Plant - cell wall, chloroplasts, etc
Animal - Centrosome and lysosomes
Why do animal cells burs in a hypotonic solution?
H2O goes in an pushes solute out
