biology glycolysis + sauerkraut quiz
What happens after ATP is made the first time and it just changed molecular form
ADP picks up the remaining phosphate group and ATP is now made. This whole process happens twice, so there are now two molecules of pyruvate.
What happens in the harvesting phase after NAD+ comes
ADP removes a phosphate group and becomes ATP. Then a change in molecular form happens and the phosphate group is moved to carbon-2.
what is the second step of glycolysis
It changes forms to now be a pentagon and becomes fructose 6 phosphate. Another ATP comes along and adds another phosphate group to carbon 1
what happens after there are two phosphate groups on the molecule
It splits into two 3-carbon molecules (3GP).
what happens after the glucose molecule splits into two
NAD+ takes a hydrogen off to make room for a phosphate group
what is stage 2 of aerobic respiration
a. prep step b. Krebs cycle, c. ETC + ATP synthase
what pathways does glycolysis happen
anaerobic and aerobic
making sauerkraut is an example of what
anaerobic cell respiration
why do you not use table salt
because it is iodized and iodine kills bacteria
why do you use glass, ceramic, or food grade plastics to store the cabbage and not metal or regular plastics
because lactic acid is corrosive
how do you create a brine in the making of sauerkraut
by adding salt too create a hypertonic environment and pull more liquid out of the cabbage
what is stage 2 of anaerobic respiration
fermentation (lactic acid or alcohol)
what is the net equation for glycolysis
glucose ---> 2 pyruvate + 2 ATP + NADH
what is another name for G3P
half of a glucose molecule with a phosphate group
where does glycolysis occur
in the cytoplasm of the cell
what are the two phases of of glycolysis called
investment and harvest phases
after glycolysis what happens to the 2 ATP made
it can be used immediately
why is glycolysis done in both anaerobic and aerobic respiration
it does not require oxygen gas
what happens to the 2 NADH made from glycolysis
it goes to stage 2
why do you want to cut the large central vacuole when making sauerkraut
lets the sugars out for bacteria to eat/breakdown
what is the first step of glycolysis
start with glucose and add a phosphate group on carbon 6 from ATP which turns to ADP. It is now glucose 6-phosphate
what does glycolysis mean
sugars break
why does it take 3 weeks for sauerkraut to be made
that is how long it takes to run out of sugar and the lactic acid kills bacteria
why do you cut the cabbage in smaller pieces when making sauerkraut
to increase surface area for more reaction and to cut through cell walls and large central vacuole
why do you cover it with a plastic bag
to make sure the cabbage stays under the brine and to keep out detritivores and decomposers
what is the main job of glycolysis
to split a singular glucose molecule into two 3-carbon molecules of pyruvate
where do you want the cabbage
under the brine and away from oxygen gas
