Chapter 2 Flashcards
List 4 kinds of biomolecules with exampoles
carbs- glucose
Protiens-hemoglobis
Lipids-phospholipids
Nucleic acids- dna/rna
True or false all organic molecules are biomolecues
false
Biomolecues ARE organic molecules but orgnic molecules ARE NOT always biomolecues
When atoms bind tightly to one onother they are called _
molecules
an atom of carbon has 4 unpaird elect
4 bonds
Covalent, polar, nonpolar
Name 2 elements whose presence contributes to a molecule becomeing a polar molecule
nitrogen and oxygen (because they are electronegative)
based on what you know from experience about the tendency of the following substances to dissolve in water, predict wether they are polar ot non polar molecules sugar and oil
sugar is polar, oil is non polar
A negativily charged ion is called a _ and a positivly charged ion is called a_
anaion, cation
Is the ph < 7, ph> 7, ph=7
acidic, alkaline (basic), neutral
A molecule that moderates change in ph is called
Proteins combines with fats are_ and protiens comebined with carbs are _
lipoproties, glycoprotein
A molecule that binds to another molecules
ligands
Match
ability of a prtein to bind one molecute but not another- specificity
The part of a protein molecule that binds the ligans - binding site
The ability of a protein to alter shapre as it binds a ligand - induced fit
An ion such as ca+2 or mg+2 that must be present in oder for an enzime to work is called
cofactor (ion +inactive= more binding)
A protein whose structure is altered to the point that its activity is destroyed is said to be
denatured (not natural anymore)
