Biology Flashcards
6carbon sugars
Glucose, fructose, galactose (hexoses)
Maltose
Glucose + Glucose
Sucrose
Glucose + fructose
Lactose
Glucose+ galactose
Polysaccharide
Glycogen(animal glucose storage), starch(Plant glucose storage), cellulose (structural)
Carboxyl group + hydrocarbon chain=
Fatty acid
Glycerol + 3 fatty acids =
Tri-glyceride (formation by dehydration)
Creates water bonds (esterification)
Glycerol + 2 fatty acids + phosphate group =
Phospholipid
Amphipathic
Both polar and non polar at same time
Terpenes
Made of 2+ isopenes
Isoprene
Terpene Unit
2 isoprene units
Terpenoids
Terpene with addition of a functional group
Cholesterol
Gibbs free energy
Gibbs free energy, enthalpy, Temperature, Entropy
Delta H is
Potential energy
T delta S is
Kinetic energy
- delta G
spontaneous
+ delta G
Non- spontaneous
Delta G = 0
Equilibrium
Exergonic
Rxn generates energy
-delta G
Endergonic
Rxn Requires input of energy
+ delta G
Delta G of atp hydrolysis
-12 kcal/mol
Active site
Where substrate binds
Almost Eric site
Binding site for structural inhibitors to bind
Zymogen
In active version of a protein
Proteolytic clevage
Cutting of protein mostly for activation
Competitive inhibitors
Binds to active site
Vmax no change
Km increased (curve shifts right)
Non-competitive inhibitors
Reduced catalytic activity but not active site shape
Vmax reduced
Km unchanged
Uncompetitive inhibitors
Binds to allosteric site of enzyme substrate complex.
Vmax reduced
Km decreases (curve shifts left)
Mixed inhibitors
Allosteric site binding for ES OR Just E
Enzyme alone: km increases vmax decreases
Es acts like uncompetitive
Line weaver burk y intercept
1/Vmax
Lineweaver burk x intercept
-1/Km
RNA polymerase I makes
rRNA
RNA Polymerase II makes
MRNA
RNA Polymerase III makes
TRNA
