How pH influences O2 saturation of hemoglobin at the same partial
pressure. - CORRECT ANSWER-pH was 7.2 and 7.4 and pressure was 90
torr - Left shift = increased affinity for O2
Right shift = decreased affinity for O2
The same torr but a 7.2 going to 7.4; higher PH would mean it would
have an increased in affinity for O2; increased in hemoglobin saturation;
reach 100% earlier
(Bohr effect): Ph is the signal for hemoglobin to let go of O2 - CORRECT
ANSWER-CHART
C: Increase Co2
H: Increase in H
A: Acidic
R: Release O2
T: Tense Tissues
,What makes LDL - CORRECT ANSWER-high cholesterol - Made of a 4
ring structure. AKA sterols (cholesterol, cortisol and testosterone). It
expands range of membernes fluid; greatest membrane fluidity. It
increases the temp to solidify.
Cholesterol is needed to synthesize - CORRECT ANSWER-vitamin D in
the skin; cholic acid, a component of bile; and steroid hormones.
steroid hormones - CORRECT ANSWER-include testosterone and
estrogen, which promote growth and the development of sex
characteristics,
cortisol - CORRECT ANSWER-which is released in response to stress and
promotes glucose synthesis in the liver
myoglobin - CORRECT ANSWER-protein with a single subunit containing
heme and iron. Normally contained only in the muscles, it can be
released into the bloodstream if there is muscle damage. For this
reason, measuring the levels of myoglobin in the blood can provide
, evidence of rhabdomyolysis, a mild heart attack, or a muscular
degenerative disease.
Anabolic pathway - CORRECT ANSWER-Anabolic pathways are those
that require energy to synthesize larger molecules. This is when there is
no O2 the ETC can not work. When NAD+ runs out it makes it with
fermentation lactate regenerates the NADH to NAD+ that was used
during glycolysis to make small amounts of ATP and lactate
Cori Cycle - CORRECT ANSWER-uses the lactate made by fermentation
in the liver and uses gluconeogenesis to covert two lactate to glucose. 2
ATP are made with each cycle but it uses 6. So the net loss is -4 ATP>
catabolic pathway - CORRECT ANSWER-those that generate energy by
breaking down larger molecules. Both types of pathways are required
for maintaining the cell's energy balance
What does cori cycle supply for red blood cells? - CORRECT ANSWER-
takes up lactate from the blood and uses gluconeogenesis pathway to
convert two molecules of lactate back to glucose. The byproduct of
