Bio 235 Midterm 1 Questions With Complete Solutions
"blast" cells Correct Answers immature cells that secrete the
ECM
"cyte" cells Correct Answers mature cells that maintain the
matrix
2 layers of serous membrane Correct Answers -pariteal-
attached to and lining a cavity-outer
-visceral-inside and covers and adheres to organs in cavity-inner
3 things that effect growth in the body size Correct Answers 1.
increase in the size of existing cells
2.increase in the number of cells
3.increase in the size of material between the cells
A band Correct Answers darker middle part of the sarcomere
extending the entire length of thick filaments-at the end of the
band is a zone of overlap where thick and thin filaments lay side
by side
A site Correct Answers aminoacyl site binds the tRNA
carrying the next amino acid and the amino acid from P gets
added. first site on the right
abdominopelvic cavity Correct Answers from the diaphragm to
the groin
abdominal cavity-stomach, spleen, liver, gallbladder, small
intestine, and large intestine
,pelvic cavity-urinary bladder, parts of the large intestine, and
internal organs of the reproductive system
abduction Correct Answers movement of bone away from
midline
Acetylcholine (ACh) Correct Answers inside each vessel and is
the chemical released at the NMJ
ACH receptor Correct Answers within each plate there are
millions of these receptor which are integral membrane proteins
to which ACh specifically binds to
acid Correct Answers a substance that dissociates into one or
more H atoms and anions
acidic solutions pH Correct Answers H is greater than OH and
ph is less than 7
acidoses Correct Answers blood ph falls below ph of 7.35
acinar gland Correct Answers rounded secretory part
acorimal end of clavicle (lateral) Correct Answers broad flat
and articulates with acromion of scapula
acromion of scapula Correct Answers lateral end of spine
projects as a flattened expanded process-high point of shoulder
,actin Correct Answers thin filaments jon together to form an an
actin filament that looks like a helix and has a binding site where
myosin head can attach
activate transport Correct Answers polar or charged molecules-
energy required to move across membrane (ATP) against the
gradient
activation energy Correct Answers collision energy needed to
break the chemical bonds of the reactants so a reaction can start
active processes Correct Answers cellular energy is used to
drive substance "uphill" against its gradient
active site Correct Answers part of enzyme that catalysis the
reaction and fits the substrate
adduction Correct Answers movement of bone toward midline-
returns abduction to normal position
Adenosine Diphosphate (ADP) Correct Answers when water is
added to ATP the 3rd phosphate is removed and the reaction
releases energy producing ADP-atpase
Adenosine Triphosphate (ATP) Correct Answers energy
currency of living systems
adherens junction Correct Answers A beltlike junctional
complex containing plaque-proteins on the inside of PM
attaching to membrane proteins and microfilaments of the
cytoskeleton. Cadherins join the cells by inserting plaque from
, opposite side of cell and connects to adherins of other cells-
helps cells resist separation during contractile activity
adipocyte Correct Answers fat cells that store triglycerides-
deep around kidneys and heart
adipose-loose connective tissue Correct Answers filled with
triglyceride droplet-deep to skin around heart kidneys , yellow
BM, pads joints energy reserve protection insulation-brown ATP
in newborns maintains body temp
aerobic respiration in muscle fibers Correct Answers occurs in
the mitochondria-pyruvic acid from glycolysis enters. When
oxygen is present glycolysis, Krebs and electron transport chain
occur. each molecule of glucose catabolized yields 30 or 32
ATP-this is for moderate exercise up to an hour
albinism Correct Answers unable to produce melanin and can't
synthesize tyrosine which makes melanin
alkalosis Correct Answers blood ph rises above ph of 7.45
alveolar processes Correct Answers ridge like arch containing
the alveoli (sockets) for the lower teeth
amino acids Correct Answers monomers of proteins each have
an hydrogen atom and three functional groups-protein is made
by joining amino acids
amphiarthrosis Correct Answers slightly moveable joint (a=a
bit)
