/.(2) Transferases - Answer-Transfer a functional group between donors and acceptors
/.(3) hydrolase - Answer-adds water to a bond
/.(4) Lyase - Answer-adds across a double bond, or removes something to form a
double bond.
/.(5) Isomerase - Answer-changes the stereoconfiguration(most common) or structural
isomers.
/.(6) ligase - Answer-joins molecules, ATP dependent
/.[E] is controlled at a genetic level - Answer-transcriptional level
/.⁺NH₄ - Answer-9.4
/.1 - Answer-ca
/.1 mole of FADH2 - Answer-1.5 mole of ATP
/.1 mole of NADH - Answer-2.5 mole of ATP
/.10 - Answer-I
/.11 - Answer-Mn
/.12 - Answer-Mo
/.13 - Answer-Se
/.14 - Answer-Zn
/.2 - Answer-k
/.3 - Answer-S
/.4 - Answer-P
,/.5 - Answer-Na
/.6 - Answer-CI
/.7 - Answer-Mg
/.8 - Answer-Fe
/.9 - Answer-Cu
/.Above the Tm Cholesterol: - Answer-decreases fluidity by limiting the free rotation of
bulky Fatty acid side chains with its bulky structure, effectively decreasing entropy.
/.acetone - Answer-20
/.Acid Base Catalysis - Answer-enzyme-substrate
⚛Specific Acid-Base: the reaction is accelerated by a proton, or hydroxyl group diffusing
from the solution
⚛general acid-base: proton or hydroxide is created in the transition state by another
molecule or group.
/.Active Transport - Answer-moves stuff from low to high concentration gradient
/.Active transport mechanism - Answer-1.3 Na bind 2. Mg 2+ binds to ATP limiting free
rotation of the beta and gamma phosphates increasing the electrophilicity of the gamma
phosphate 3. ATP binds, opening the pump to the outside of the cell, releasing sodium,
closes sodium binding site 4. structural rearrangement-close Na+, open K+ 5. Structural
Change, Allows Phosphate to be hydrolyzed.
/.Alanine - Answer-
/.alkane - Answer-60
/.alkene - Answer-44
/.alkyne - Answer-25
/.ALL RNAs are transcribed from DNA - Answer-...
/.Allosteric regulation - Answer-an allosteric effector decreases km,
small organic-food or protein
if the allosteric effector is a positive effector
/.alpha helix - Answer-small R groups, Linear R groups
Unbranched, Most common helix
/.Amino acyl tRNA synthetases require the hydrolysis of ATP/GTP specifically - Answer-
...
/.Amylase produces - Answer-di and trisacharides
/.Anabolism - Answer-Synrhesis of biomolecules takes energy
/.anything that breaks the pH gradient is a - Answer-uncoupler
/.Apoenzyme - Answer-nonfunctional enzyme, due to absent coenzyme, prosthetic
group or metal
/.Aquaporins - Answer-mostly alpha shape, allows water to move very quickly compared
to diffusion
/.Arachidic Acid - Answer-20:∆0
/.Arachidonic acid - Answer-20:∆5,8,11,14
/.arginine - Answer-pka 12.5
/.arginine pka - Answer-12.5
/.asparagine - Answer-
/.aspartic acid - Answer-pka 3
/.Aspartic acid pKa - Answer-3.9
/.Below the Tm Cholesterol: - Answer-increases the fluidity by preventing the Fatty Acid
side chains from packing in.
/.benzene - Answer-43
/.Beta Sheet - Answer-Planar component (molecule) two types: parallel and anti parallel
parallel must loop out of plane, more 3D than antiparallel
/.Carboxylic Acid (CO₂H) - Answer-4.8
/.carrier protein facilitated transport - Answer-very slow, inefficient but allows mucho
control
/.Catabolism - Answer-Breakdown of food to co2+water makes energy
