Subjects : science, ap, biology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Plants that produce offspring of the same variety when they self-pollinate.






2. The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water.






3. The coupling of the 'downhill' diffusion of one substance to the 'uphill' transport of another against its own concentration gradient.






4. The entire contents of the cell - exclusive of the nucleus - and bounded by the plasma membrane.






5. An ion transport protein generating voltage across the membrane.






6. A covalent bond formed between two monosaccharides by a dehydration reaction.






7. A cell creates a vesicle around a droplet of extracellular fluid






8. Complete complement of organisms genes; genetic material






9. The simplest carbohydrate - active alone or serving as a monomer for disaccharides and polysaccharides. Also known as simple sugars - the molecular formulas of are generally some multiple of CH2O.






10. Rain - snow - or fog that is more acidic than pH 5.6.






11. A subatomic particle with single positive charge found in nucleus of an atom






12. Dissolving agent of a solution






13. A substance that is dissolved in a solution






14. A plant that prefaces the Calvin cycle with reactions that incorporate CO2 into four-carbon compounds - the end product of which supplies CO2 for the Calvin cycle.






15. The synthesis of RNA on a DNA template.






16. The removal of noncoding portions (introns) of the RNA molecule after initial synthesis.






17. A basic principle in biology stating that genes are located on chromosomes and that the behavior of chromosomes during meiosis accounts for inheritance patterns.






18. Smallest unit of matter that retains property of an element






19. Golgi appartus--> usually located near the ER a vesicle that buds from the ER will add its membrane and the contents of its lumen -cavity - to this face






20. A type of endocytosis involving large - particulate substances.






21. Collagen most abundant in animal cells






22. Actin (tension bearing elements ) muscle contraction






23. One of several organic compounds with the same molecular formula but different structures and therefore different properties. The three types are structural - geometric and enantiomers.






24. A type of strong chemical bond in which two atoms share one pair of valence electrons






25. The synthesis of a polypeptide using the genetic information encoded in an mRNA molecule. There is a change of 'language' from nucleotides to amino acids






26. The movement of specific molecules into a cell by the inward budding of membranous vesicles containing proteins with receptor sites specific to the molecules being taken in; enables a cell to acquire bulk quantities of specific substances.






27. Organizing the structures and activities of cells






28. One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P700 reaction-center chlorophyll.






29. A fatty acid in which all carbons in the hydrocarbon tail are connected by single bonds - thus maximizing the number of hydrogen atoms that can attach to the carbon skeleton.






30. Many ion channels function as gated channels these channels open or close depending on the presence or absence of a chemical or physical stimulus






31. An additive effect of two or more gene loci on a single phenotypic character.






32. A cyclically operating set of molecultes in the cell that triggers and coordinates key events in the cell cycle






33. A mass of abnormal cells within otherwise normal tissue - caused by the uncontrolled growth of a transformed cell






34. A microscope that focuses an electron beam through a specimen - resulting in resolving power a thousandfold greater than that of a light microscope. A transmission electron microscope (TEM) is used to study the internal structure of thin sections of






35. The cellular secretion of macromolecules by the fusion of vesicles with the plasma membrane.






36. The passive movement of molecules down their concentration gradient via transport proteins






37. A solution in which water is the solvent






38. An extensively branched glucose storage polysaccharide found in the liver and muscle of animals; the animal equivalent of starch.






39. A molecule that binds specifically to a receptor site of another molecule.






40. Uses energy to move solutes against their gradients; requires the cell to expend metabolic energy; enables a cell to maintain its internal concentrations of small molecules that would otherwise diffuse across he membrane ; ATP supplies the energy for






41. The passive transport of water; diffusion of water across a selectively permeable membrane; the direction of osmosis is determined only by a difference in total solute concentration ; the kind of solutes in the solution do not matter






42. A substance that reduces the activity of an enzyme by binding to a location remote from the active site - changing its conformation so that it no longer binds to the substrate.






43. An acceptor that temporarily stores energized electrons produced during the light reactions.






44. Drive the diffusion of ions across a membrane 1. chemical force based on an ions concentration gradient. 2. the other is an electrical force based on the effect of the membrane potential on the ion's movement ion diffuses down its electrochemical gra






45. An ion with a positive charge produced by the loss of one or more electrons






46. Having aversion to water tend to coalesce and form droplets of water






47. A metabolic pathway that consumes oxygen - releases carbon dioxide - generates no ATP - and decreases photosynthetic output; generally occurs on hot - dry - bright days - when stomata close and the oxygen concentration in the leaf exceeds that of car






48. Sequence of events in the life of a cell - from its origin in the division of a parent cell until its own division into two composed of M - G1 - S - and G2 phases






49. A functional group present in aldehydes and ketones and consisting of a carbon atom double-bonded to an oxygen atom.






50. That portion of the endoplasmic reticulum studded with ribosomes.
