527. Complementary base pairing occurs in the transcription, translation, and DNA replication. 528. Glycogen is a macromolecule. 529. If J has a positive effect on K, then an increase in the value of K may not have any effect on the value of J. 530. Hypothermia can lead to a positive feedback loop that is life threatening. 531. Proteins within a sodium-potassium pump could be characterized by one of the letters in TRICCS studied in chapter 3. 532. RNA polymerase is made in translation and it is required in G1 phase of the cell cycle? 533. In a typical feedback loop, information must be sent out of a receptor. 534. Vesicles destined for exocytosis do not originate at the plasma membrane. 535. Hydrostatic pressure increases within a cell if there is a net movement of water into the cell. 536. Solutions with a lower concentration of “bound” water molecules than human cells are hypotonic to human cells. 537. The literal meanings of “dissection” and “anatomy” are virtually the same. 538. The body’s temperature is l ikely to decrease when more sweat is secreted. 539. Three codons out of the 64 possible do not code for amino acids during translation. 540. The saturation point is a phenomenon associated with how many particles can pass through a carrier in a certain time. 541. A polymer is a macromolecule. 542. A ribosome reads mRNA in a 5’ to 3’ direction. 543. An example of a non-membranous organelle is a ribosome. 544. The process of phagocytosis transports larger materials than does pinocytosis. 545. Hydration shells form around ions and parts of amphipathic molecules. 546. All transmembrane proteins are integral proteins. 547. Sulfa drugs inhibit certain bacteria through allosteric inhibition of enzymes in those bacteria. 548. Pseudopodia are more related to actin than to tubulin. 549. All enzymes are proteins. 550. The pH of a solution is not the solution’s hydrogen ion concentration in moles/liter. 551. If a round cell flattens out, it may be better able to expel wastes and take in nutrients more efficiently 552. All DNA polymerases are synthesized at ribosomes.

A DNA polymerase II molecule is responsible for DNA proofreading. 555. Intercellular fluid is considered a cell’s external environment when discussing homeostasis in the body. 556. Adapting to one’s climate o r altitude is termed acclimatization. 557. The polar fibers elongate as two centrosomes move farther apart. 558. Cholesterol helps prevent a plasma membrane from becoming brittle under lower-than-normal temperatures. 559. Galactose has the same number of neutrons as glucose. 560. The acronym for the characteristics of life is a mnemonic device. 561. Ribosomes synthesize oxidases and catalases that later become incorporated into peroxisomes. 562. The proteins that bind to rRNA molecules to form ribosomal subunits are made in a process called translation.
