CAM cycle.
carbon cycle.
Calvin cycle.
Krebs cycle.
Biology
Human Physiology - GeneralAs many as 25 persons can benefit from a single organ and tissue donor. Thousands of people
are in need of an organ or tissue transplant, and anyone, regardless of age, race, or gender can
be a donor. Organs that cannot be placed are often used for research on a variety of diseases
and conditions. Which of the following body parts is a tissue that could be used in a
transplant?
A. heart
B. kidney
C. cornea
D. pancreas
E. lungs
Biology
Human Physiology - GeneralWhat best explains the unexpected findings in your data?
Over reporting due to feigning (faking illness)
Under reporting of incidents
Over reporting due to false positives
Contamination of lab samples
Biology
Human Physiology - GeneralDuring steps 6 and 7 of glycolysis, where does the energy come from to create the high energy
intermediate
1,3-bisphophoglycerate?
From the hydrolysis of ATP
From the oxidation of NADH
From the substrate level phosphorylation of ATP
From the oxidation of glyceraldehyde 3-phosphate
Biology
Human Physiology - GeneralIn eukaryotic cells, the citric acid cycle occurs in
the cytosol
the mitochondrial matrix
the intermembrane space
the lysosome
Biology
Human Physiology - GeneralWhat hormone causes dwarfism or gigantism in children when levels are improprerly regulated?
GH
TSH
ACTH
FSH
LH
Biology
Human Physiology - GeneralWhat behaviors are considered cardioprotective?
Limit fats to <20% of daily calories, with the majority of those fats being saturated fats
Limit the amount of fiber in your diet
All of the above
Don't smoke, or reduce smoking if you are not ready to quit
Biology
Human Physiology - GeneralWhich of the following explains how cells become specialized
to develop into parts of organ systems?
one:
Cells join together with others that have the same
function, which produces organs.
Cells perform chemical reactions that change their
physiology, which allows them to become organs.
Cells develop in particular areas of the body, which gives
them the same functions.
Cells undergo differentiation during their development,
which activates particular genes.
Biology
Human Physiology - GeneralWhat mechanism allows the Na*/Glucose symport to move glucose into cells against the glucose concentration gradient?
A. The symport uses ATP to power glucose and Na* import.
B. The symport pumps Na* out of the cytosol to make room for imported glucose.
C. The symport can only change conformation and import Na* if it is also importing glucose.
D. The symport can't move glucose against its gradient and will actually export glucose to the gut lumen between meals.
Biology
Human Physiology - GeneralAcetylcholinesterase degrades acetylcholine shortly after it is released by neurons at neuromuscular junctions. What would happen if acetylcholinesterase was inhibited by a toxin?
A. Muscles would not be able to contract (known as flaccid paralysis)
B. Muscles would continually contract and not relax (known as rigid paralysis)
C. Muscles would behave normally.
Biology
Human Physiology - GeneralWhat happens if an initial stimulus is not sufficient for a neuron's membrane to reach the threshold
potential?
A. No action potential will occur and the membrane will return to resting membrane potential.
B. No action potential will occur, but the membrane will not recover its resting membrane potential.
C. The action potential will still occur, but the depolarization won't be as strong.
