Nursing 504 Pathophysiology Across The life Span McCance
1, 2, 4, 5, 6 Questions With Complete Solutions
8 functions of cells Correct Answers -movement
-conductivity
-communication
-absorption
-excretion
-secretion
-respiration
-reproduction
accumulation Correct Answers harms cells by crowding the
organelles and by causing excessive metabolites to be produced
during catabolism and released into the cytoplasm or expelled
into the extracellular matrix
action potential Correct Answers when a cell receives an
electrochemical stimulus, cations enter the cell, causing a rapid
change in the resting membrane potential
active transport Correct Answers -movement of larger
molecules into the cell
-uses ATP as energy
adaptation Correct Answers an alteration that enables the cell to
maintain a steady state despite adverse conditions
adenine Correct Answers thymine
,allele Correct Answers different form of genes located at the
same locus on a chromosome
amphipathic Correct Answers hydrophobic and hydrophilic
ends
anabolism Correct Answers energy-using process
anaphase Correct Answers phase of the cell cycle where
centromeres split; chromatids pull apart; these are now
chromosomes
aneuploid Correct Answers somatic cells that do not have a
multiple of 23 chromosomes
-result of nondisjunction
angelman Correct Answers inherited from mother
anions Correct Answers negatively charged electrons
antiport Correct Answers mediated transport of two molecules
simultaneously in opposite directions
apoptosis Correct Answers causes loss of cells by -severe cell
injury
-accumulation of misfolded proteins
-viral infections
-obstruction in tissue ducts
apoptosis Correct Answers selective cellular self-destruction
called programmed cell death
, ATP Correct Answers energy-transferring molecule
ATP Correct Answers generated in the mitochondria
atrophy Correct Answers decrease in cell size
autosomal dominant Correct Answers -inheritance is rare
-does not skip generations
-recurrence risk is 50%
autosomal recessive Correct Answers -parents are both
heterozygous carriers
-recurrence risk is 25%
-males and female equally likely to be affected
autosomes Correct Answers 22 pairs of chromosomes
barr body Correct Answers females have 1, males have 0
base pair substitution Correct Answers mutation where there is
a replacement of one base pair by another
basement membrane Correct Answers thin layer of connective
tissue underlying the epithelium of many organs
beckwith-wiedernmann Correct Answers overgrowth condition
Ca++ Correct Answers second messenger pathway based on
binding of 1st messengers to surface receptors that activate
phospholipase C
