2026 VERIFIED QUESTIONS WITH
ANSWERS
◉cori cycle process (step 2). Answer: lactate -> liver
(=cardiovascular system)liver convert lactate to glucose =
gluconeogenesis
◉cori cycle process (step 3). Answer: glucose enter bloodstream
◉gluconeogenesis. Answer: biosynthesis of glucose from
noncarbohydrate sources, important for blood glucose regulation
◉What is gluconeogenesis?. Answer: biosynthesis of glucose from
non-carbohydrate sources (pyruvate, lactate, amino acid, glycerol)
◉where does gluconeogenesis occur?. Answer: liver and kidney cell
◉Gluconeogenesis occurs when. Answer: glucose level is low, cant
deliver O2 (strenuous activity, fasting, lack of carbohydrate diet)
,◉what happens during strenuous activity?. Answer: lungs/
circulatory system can't deliver enough O2 to working muscle ->
muscle run out of glucose and glycogen low O2-> carry out glycolysis
and lactate ferm
◉what is the abnormal conditions that occur when the Cori cycle
takes place.. Answer: strenuous activity: high metabolic activity +
low [O2]
◉what kind of regulated system does ATP have on kreb's cycle?.
Answer: negatively, cell already has enough ATP -> slow down Kreb's
cycle
◉what kind of regulated system does ADP have on kreb's cycle?.
Answer: positive, cell need more ATP
◉what kind of regulated system does NAD+ have on kreb's cycle?.
Answer: positive: cell has many e- carrier to be reduced -> increase
rate of KC
◉what kind of regulated system does NADH have on kreb's cycle?.
Answer: negative, already has the products -> decrease rate of KC
◉what kind of regulated system does acetyl coA have on kreb's
cycle?. Answer: negative
, ◉what kind of regulated system does glucose-6-phosphate have on
glycolysis?. Answer: negative
◉How will increasing concentrations of AMP affect glycolysis?.
Answer: Positively, ATP being used -> need more ATP -> enhance
glycolysis
◉How will increasing concentrations of ATP affect glycolysis?.
Answer: negatively, cell already has enough ATP -> slow down
glycolysis
◉How will increasing concentrations of citrate affect glycolysis?.
Answer: negavtively, cell doesn't need glycolysis to produce more
Acetyl coA (already has ATP)
◉How will increasing concentrations of acetyl coA affect glycolysis?.
Answer: negatively, cell doesn't need glycolysis to produce more
Acetyl coA (already has ATP)
◉in glycolysis regulation, if decrease demand. Answer: product
build up, signal to stop/ slow down supply
◉in glycolysis regulation, if the demand exist. Answer: products of
pathway are consumed, pathway acts to supply products
