ADVANCE NUTRITION AND HUMAN
METABOLISM TEST BANK EXAM QUESTIONS
WITH 100% COMPLETE SOLUTIONS
cells - ANS-the basic living, structural, and functional units of the human body; they can vary in size,
chemical composition, and function; they can move, grow, ingest and excrete food/waste, react to their
environment, and reproduce
eukaryotic cells - ANS-cells of all multicellular organisms that developed/evolved from prokaryotic cells;
have a defined nucleus
prokaryotic cells - ANS-primitive cells that do not contain a defined nucleus
A plasma membrane and a nucleus - ANS-can be found in all human cells
An endoplasmic reticulum, a Golgi apparatus, and mitochondria - ANS-are found in most, but not all,
human cells
Plasma membrane - ANS-forms the outer boundary of a cell making it a distinct unit;
Membranes - ANS-sheet-like structures composed primarily of phospholipids and proteins held together
by noncovalent interactions; they are asymmetrical (the inside and outside faces are different)
Membrane phospholibids - ANS-have both a hydrophobic and hydrophilic moiety which allows them to
spontaneously form bimolecular sheets in water called lipid bilayers
Phosphoglycerides and phosphingolipids - ANS-comprise most of the membrane phospholipids
Phosphingolipids - ANS-phosphate-containing sphingolipids
Cholesterol - ANS-Found in the hydrophobic portion of the bilayer in amounts that vary considerably
from membrane to membrane; it is there to create structure and maintain fluidity; if there is a lot of this
present, the membranes are less fluid
Membrane proteins - ANS-These give biological membranes their functions: pumps, gates, receptors,
energy transducers, and enzymes; many of these have lipid or carbohydrate attachments
