[问答题]
8. ATP is an allosteric inhibitor of phosphofr x sm8f;wfjhnq-3hb.2 t+nx.nuctokinase6ht+xrjcet k0 x 2u6i8 (1.swqky8oxl 9zgln5 and pyruvate kinase, two enzymes involved in glycol.hsju+9 kiq6t l0 zr2ylt (ox5xc 8xn1g6kw 8eysis. Discuss the importance of feedback inhibition of metabolic pathways in biological systems using this as an example.




参考答案:
Feedback inhibition is allosteric inhibition of enzymes.
Feedback inhibition is reversible.
The degree of inhibition depends on the concentration of inhibitor.
As ATP builds up in concentration and is not being utilised by the cell.
This ATP build up will inhibit glycolysis.
And the rate of respiration of the cell will decrease.
When the cell uses the ATP and becomes more metabolically active.
Inhibition will stop, the rate of glycolysis will increase.
ATP is able to inhibit its own production when it is not being utilised/the rate of respiration is controlled by the rate at which ATP is being used.
