Biology
Describe an allele that requires two copies to be expressed.
Recessive
The last codon of translation (UAA, UGA, or UAG); release factor binds here, terminating translation.
Stop Codon
The charge assigned to an atom in a molecule or polyatomic ion, assuming even division of the electrons in a bond.
Formal Charge
Compounds consisting of only carbons and hydrogens bonded with sigma bonds.
Alkanes
A vector quantity describing a change in velocity over the elapsed time during which that change occurs
Acceleration
A system of tubules that provides channels for iron flow throughout skeletal and cardiac muscle fibers to facilitate the propagation of an action potential.
Transverse Tubules (T-Tubules)
A portion of that is spliced out from mRNA; remains in the nucleus during process.
Intron
What is the Bronsted-Lowry Definition?
Acids as proton (H+) donors and bases as proton acceptors
Describes groups on a cyclic molecule that are perpendicular to the plane of the molecule, pointing straight up or down.
Axial
The law describing the electrostatic force that exists between two charges, q1 and q2
Coulomb's Law
The innermost of the three primary germ layers; gives rise to the linings of the digestive and respiratory tracts and to parts of the liver, pancreas, thyroid, and bladder.
Endoderm
An important metabolic intermediate that can feed into the citric acid cycle, fermentation, or gluconeogenesis.
Pyruvate
A chemical reaction in which an atom or ion of one compound is replaced by another atom or ion (such as A + BC -> B + AC).
Single-Displacement Reaction
The process that transforms one ester to another when an alcohol acts as a nucleophile and displaced the alkoxy group on an ester.
Transesterification
The spreading-out effect of light when it passes through a small slit opening.
Diffraction
A protein secreted by parietal cells of the stomach that is necessary for vitamin B12 absorption.
Intrinsic Factor
The inhibition of an enzyme by its product (or a product further down in a metabolic pathway); used to maintain homeostasis.
Feedback Inhibition
The product of the molar concentrations of dissociated ions in a saturated solution, where each ion is raised to the power of its stoichiometric coefficient.
Solubility Product Constant
Increased energy that results when molecules assume eclipsed or gauche staggered conformations.
Torsional Strain
State the name and the equation describing the angle refraction for a light ray passing from one medium to another.
Snell's Law: n1 sin θ1 = n2 sin θ2, where n represents the index of refraction in each medium.
Series of events, starting with the binding of a peptide hormone to a surface receptor. This sequence of events ultimately results in a change in cellular behavior.
Signaling Cascade
The movement of solute molecules through the cell membrane down their concentration gradient through a transport protein or channel; used for ions and large or polar molecules.
Facilitated Diffusion
The energy released when an atom or ion in the gaseous state gains an electron. Increases from left to right and from bottom to top on the Periodic Table.
Electron Affinity
A functional group that contains a carbon atom bonded to two -OR groups, an alkyl chain, and a hydrogen atom.
Acetal
Magnification is a dimensionless value denoted by m given by the equation: _______, where i is _____ and o is _____. A negative m denotes an ____ image, whereas a positive m denotes an _____ image.
(Hint: Find the equation, remember what each variable stand for and which condition will produce an inverted vs upright image).
m = -i/o, image distance, object distance, inverted image, upright image.
