carbohydrates

Question 1

glycolysis rate limiting enzyme
& step

Answer 1

phosphofructokinase-1
fructose6phosphate -> fructose1,6biphosphate

Question 2

main steps glycolysis

Answer 2

glucose -> glucose-6-phosphate
-> fructose 6 phosphate -> (pfk-1)
fructose1,6- biphosphate ->->->—>
phosphoenolpyruvate —> (pyruvate kinase) 2 x PYRUVATE

Question 3

gluconeogenesis occurs mainly in (organs & cellular level)

Answer 3

liver & kidneys, both cytosol and mitochondria

Question 4

main substrates for gluconeogenesis

Answer 4

глюкогенни аминокиселини
лактати и пирувати
глицерол
пропионова киселина

Question 5

Lactic acid fementation
(enzyme, steps, net gain)

Answer 5

2 pyruvate —> 2 lactate
enzyme: Lactate Dehydrogenase
2NADH -> 2NAD+

2Lactate -> 2lactic acid
generating 2ATP

BACTERIAL CYTOSOL

Question 6

Éthanol fermentation

Answer 6

Pyruvate -> acetaldehyde -> ethanol
nadh-> nad

net gain per glucose 2ATP
