HSS 386 Final ALT Questions And All
Correct Solutions| Update 26
individuals with this disease lack the enzymes needed for autophagy and
autolysis - Ans--tay-sachs
what is used as the final electron acceptor in oxidative phosphorylation -
Ans--oxygen
what is meant by the notion that sidenafil is used as an unexpected oral
therapy for erectile dysfunction? - Ans--siidenafil was being investigated for
treatment of angina with unexpected side effects
simple squamous epithelia is optimal for ______ and is found in _______. -
Ans--rapid diffusion of oxygen, alveoli
which of the following are used by our bodies to maintain pH of 7.35-7.45
during high intensity exercise - Ans--bicarbonate, buffers
the movement of K+ along its concentration gradient through leak channels
represents what type of membrane transport? - Ans--facilitated diffusion
the absence of charged (activated) tRNA with the anticodon TAC would
impact _____ by directly effecting _______ - Ans--translation, initiation
Which of the following statements is false regarding CAC? - Ans--FADH,
NADH and pyruvate are produced (wrong because no pyruvate), and
lactate used as substrate
during translational elongation, activated tRNA with the anticodon
sequence (GTT-CAC-ACC) results in what amino acid sequence? - Ans--
none of the above
increased permeability of this channel caused hypopolarization through
facilitated diffusion - Ans--voltage gated Na
, which of the following answers is false regarding anatomical directional
terms? - Ans--a fracture of a rib on the side of the body is medial to the
sternum
a rapid lowering of blood pressure that is detected in the body and quickly
restored to a normal level represents what component of a homeostatic
control mechanism - Ans--stimulus
which of the following defines the study of cells - Ans--cytology
excessive amounts of ATP can impact glycolysis by - Ans--allosteric
inhibition of PFK activity
Which of the following answers are true regarding patients with type 2
diabetes and mitochondrial activity:
- metformin is known to reduce activity of complex one in the ETC
-metformin leads to a build up of NADH
-Metformin can cause limitations to VO2 max in older adults
-all of the above - Ans--all of the above
T/F: competitive inhibition involves allosteric inhibition allowing changing of
shape of an enzyme - Ans--false
T/F: following the release of newly synthesized proteins, their transport
vesicles are released from the rough ER and with the golgi apparatus at the
trans-face - Ans--False
T/F: The high concentration of H+ in the mitochondrial intermembrane and
subsequent movement down its concentration gradient supplies energy
needed for ATP synthesis and is an example of the first law of
thermodynamics that states 'energy can neither be created nor destroyed, it
can only change in form' - Ans--true
T/F: the active site on an enzyme allows for only one specific substrate to
bind and an example of this is the active site on pyruvate for fructose 6
phosphate - Ans--true
