Bio Flashcards
Structure of alpha glucose
1, 2, 4 and 5 hydroxides are below the carbon chain
What is a phenol
A hydroxyl attached to a phenyl
What functional groups make molecules polar
Hydroxyls, both types of carbonyls, carboxyls, amines, thiols, ethers
Whats an important feature of lipids
Alkene
Whats a defining feature of proteins
Aminos, carboxyls and amides
Defining features of carbs
Hydroxyls and both types of carbonyls
Why does pH cause denaturization
It causes functional groups to be deprotonated or protonated, adding or removing positive charges breaking hydrogen bonds since they exist due to the interactions between positive and negative charges
Why aren’t ribosomes organelles
They have no membrane
Eukaryotic cells are ‘compartmentalized’ wuzat mean
SpecifiC functions are done in specific organelles
How do carbs cyclize
The electrons of the double bond of an aldehyde or ketone break lose and attract a proton
What amino acid is slightly basic
Amino
What functional group is transferred back and forth between biological molecules
Phosphate
What is a vesicle that contains mostly water
A vacuole
Function of the cytoskeleton
Maintain and change cell shape, frame work for compartmentalization
What organisms have cell walls
Prokaryotes, plants and fungi
