    The neuromuscular junction between a skeletal muscle and a motor nerve can ONLY USE ACETYLCHOLINE (ACh) AS THE NEUROTRANSMITTER. The action potential spreads along the sarcolemma and down specialized T-tubules that dive deep into the muscle cell, causing the release of Ca2+.
  41. Contraction
    • -The default low-energy position for myosin heads is bent. ATP is used to force, or "cock", these myosin heads into a high-energy, straight position.

    No color change either means it is in the opposite solution, or that the solution is neutral.
  250. Metathesis reaction
    AB+CD → AD+CB
  251. Ksp concentration trends
    The lower the value of Ksp is, the lower the concentrations of the cation and anion in an aqueous solution and the lower the solubility of the compound in water.
  252. Which of the characteristics of sound (frequency, wavelength, intensity, speed) remains constant in still air?
  253. Ohm's law in the cardiovascular system

  254. With O-Chem structures, the predominant conformation is also the _______ and has the _______ substituent in the _______ position.
    most stable, largest, equatorial.
  255. Allosteric Site
    A site on a multi-subunit enzyme that is not the substrate binding site (not the active site) but that when reversibly bound by an effector induces a conformational change in the enzyme, altering its catalytic properties.
  256. When saponifying a triacylglycerol, how many OH ions are required?
    Three equivalents, because one OH ion is required to hydrolyze one ester linkage of a triacylglycerol molecule.
  257. What digestive system substances are produced in the pancreas?
    Several proteolytic enzymes, which are released into the small intestine and converted to their active forms of trypsin, chymotrypsin, and carboxypeptidase.
  258. What is one characteristic that distinguishes eukaryotic cells from prokaryotic cells?
    Eukaryotic cells contain membrane-bound organelles such as mitochondria.
  259. From what germ layer does heart tissue differentiate?
  260. Where are sex-linked genetic traits found?
    Either on a sex chromosome (X, Y) or on an autosome.
  261. An inhibitor of microtubule reorganization prevents what?

    Phagocytosis requires that the cell change shape dramatically as is surrounds and engulfs large extracellular particles. This function relies on the microtubules to disassemble and reorganize. Inhibiting microtubule reorganization would therefore prevent phagocytosis.
  262. How to determine the number of different possible gametes that can be formed by diploid organisms.

    Where n is the haploid number of chromosomes.Ex. AaBbCc has 3 haploid chromosomes and so 23 is 8
  263. What occurs during mitosis but not during meiosis I?
    The splitting of centromeres.One difference between these two mechanisms is during respective anaphases. During anaphase in mitosis, sister chromatids are pulled apart. During anaphase of meiosis I, homologous pairs are separated into two daughter cells. It is not until anaphase II in meiosis that the centromere is split.
  264. Transcription of DNA into RNA occurs in the _______
  265. Translation of RNA into proteins occurs in the _______

    This is done by ribosomes.

  275. Cosine 90˚
  276. Method for solving fractions, with a fraction in the denominator.
    Multiply the top and bottom of the primary fraction, by the reciprocal of the fraction in the denominator. This will make the top a new fraction and the bottom one.

    • Ex.
  277. If you have 4/3 of an original quantity, then the final amount has...
    Increased by 1/3
