Understanding Pathophysiology 7th Edition Test Bank Chapter 1. Cellular Biology MULTIPLE CHOICE 1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? a. A single circular chromosome b. A nucleus c. Free-floating nuclear material d. No organelles ANS: B The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its nucleus; thus,...

"Proton hopping" essentially means that: A) an individual proton "jumps" from one electronegative group to the next. B) a free proton moves from one hydroxyl group of ionized water to the next. C) several protons move between hydrogen bonded water molecules causing the net movement of a photon over a long distance in a short time. D) individual protons are freer to move among and between water molecules in solution. E) hydronium ions are freer to move among and between water molecules ...

IB Biology Topic 1: Cell Biology Latest Update Graded A Cell theory The theory that cells form the fundamental structural and functional units of all living organisms. Differentiation The expression of a particular gene(s) and not others in order for cell specialisation. Emergent properties The idea that the sum of an organism is more than the parts interacting and combining. Living things become more complex as they move (from individual cells to organ systems). Multicellular...

amphipathic molecules - molecules with both hydrophilic and hydrophobic properties approaches of antibiotics - -inhibition of cell wall formation --beta lactam -inhibition of cell membrane function -inhibition of DNA synthesis -inhibition of protein synthesis -inhibition of nucleic acid synthesis aqueous environment - -polar water environment that interacts with other polar molecules/ions (hydrophilic molecules) -formation of hydrogen bonds -environment doesn't react with nonpolar sub...

active site (biochemistry) - the region of an enzyme that binds to a protein or to another substance during a reaction, where catalytic activity occurs allosteric site (biochemistry) - site at which a small regulatory molecule interacts with an enzyme to inhibit or active that specific enzyme, binding of allosteric effector is in general noncovalent and reversible amino acid (biochemistry / molecular genetics) - a simple organic compound containing a carboxyl group and an amino group am...

Membranes are composed of which two macromolecules? Lipids and Proteins What are the 3 kinds of Lipids that make up membranes? Are they polar, non polar, or amphipathic? Phospholipids (most abundant) Glycolipids (sugar head) Sterols (like cholesterol) They are amphipathic How are integral proteins associated with the membrane? They are directly attached to the membrane How are peripheral proteins associated with the membrane? They aren't directly attached, but are associated with m...

The dipole moment in a water molecule Which statement about hydrogen bonds is NOT true? A) Hydrogen bonds account for the anomalously high boiling point of water. B) In liquid water, the average water molecule forms hydrogen bonds with three to four other water molecules. C) Individual hydrogen bonds are much weaker than covalent bonds. D) Individual hydrogen bonds in liquid water exist for many seconds and sometimes for minutes. E) The strength of a hydrogen bond depends on the linearit...
