|
corneal anaerobic and aerobic glycolysis takes place in the
|
endothelium
|
|
|
in anaerobic glycolysis what conversion takes place?
|
pyruvate is converted to lactate by lactate dehydrogenase (LDH)
|
|
|
how does the use of LDH keep glycolysis active?
|
it recycles NADH produced during glycolysis to NAD+ which is used for glycolysis
|
|
|
LDH is functional at what level of structure?
|
quaternary
|
|
|
H polypeptide is used when there is ____, M is used for _____
|
a lot of oxygen, when there is not
|
|
|
H polypeptide favors converting ______, so that _____
|
lactate to pyruvate, make more energy via the kreb's cycle.
|
|
|
M polypeptide favors
|
converting pyruvate to lactate to get a quick supply of energy by keeping glycolysis alive
|
|
|
the cornea prefers which polypeptide?
|
M, and thus usally uses pyruvate conversion to lactate for recycling of NADH
|
|
|
low energy would fluctuate hydration how in the cornea?
|
low energy would case an increase in hydration since the Na+ concentration gradient will not be maintained
|
|
|
pyruvate dehydrogenase
|
converts pyruvate into acetyl CoA in the mitochondria
|
|
|
after acetyl CoA is created in the mitochondria by pyruvate dehydrogenase, what then happens to it?
|
it is fed into the kreb's cycle
|
|
|
for each acetyl group that enter the kreb's cycle,
|
3 NADH are produced, also some FADH and GTP
|
|
|
how many transmembrane complexes make up the ETC? where is it located?
|
4 complexes , the inner mitochondrial membrane
|
|
|
complex I accepts __ electrons from NADH. Where is it transferred from here?
|
2, complex 1 --> CoQ--->III---->cytochrome c----> complex IV---->O2
|
|
|
energy created from ETC pumps protons from ____ to the ____
|
matrix to the intermembrane space
|
|
|
Complex II accepts 2 electrons from ___. These electron's energy is used in ____
|
FADH, heat production
|
|
|
ATP formation occurs where in the ETC?
|
complex I, III, IV
|
|
|
the inner mitochondrial membrane is ___ to protons
|
impermeable
|
|
|
increaed hydration in the cornea results in what?
|
cloudy cornea
|
