Biology Major Field Test Study Set Exam
questions 2026 Exam Questions and
verified Answers
what is the general fatty acid formula - CORRECT ANSWERS CH3(CH2)nCOOH where n= an
even number between 12 and 24
glycerides - CORRECT ANSWERS glycerol and 3 fatty acids
nucleotide is composed of - CORRECT ANSWERS phosphate group; sugar group; nitrogenous
base
Vmax - CORRECT ANSWERS maximum reaction rate at which point substrate is saturated
with enzyme
Competitive Inhibition - CORRECT ANSWERS molecules compete with substrate for enzyme's
active sites
irreversible inhibitors - CORRECT ANSWERS chemically and covalently bind to active site;
rendering it permanently inactive
psuedoirreversible inhibitors - CORRECT ANSWERS extremely high affinities for active site;
hard to displace
noncompetitive inhibitors - CORRECT ANSWERS do not compete for active site but act
elsewhere on enz.; altering 3D shape
, electron transport chain - CORRECT ANSWERS series of carrier molecules on the inner
mitochondrial membrane which pass electrons through enzymes that pump protons to one side of the
membrane, creating a proton gradient
chemiosmosis - CORRECT ANSWERS the use of a gradient, such as a proton gradient, to
generate energy. The ATP synthase enzyme uses the kinetic movement of protons down the gradient to
store energy by converting ADP to ATP
ATP - CORRECT ANSWERS Adenosine tri phosphate, a modified nucleotide that stores energy
in it's phosphate bonds.
fermentation - CORRECT ANSWERS glycolysis and the additional steps leading to the
formation of ethanol or lactic acid, to make ATP. It does not include the Kreb's cycle (producing CO2) or
the ETC.
occluding/tight junctions - CORRECT ANSWERS nothing can diffuse between cells or past
junction
anchoring junctions - CORRECT ANSWERS physical joining so cells do not shear away
communicating junctions - CORRECT ANSWERS gap junctions are formed by proteins called
connexins that allow for undisrupted and very fast signal transmission
plasmodesmata - CORRECT ANSWERS plant cells' equivalent of gap junctions
G-actin - CORRECT ANSWERS globular monomer
F-actin - CORRECT ANSWERS long filament
