Regulations of glycolysis What are the effects on glycolysis if high concentrations of the following were present? 1) glucose-6-phosphate – decreases concentration of pyruvate because at high concentrations, it inhibits hexokinase (too much g-6-P means no need to convert more glucose into g-6-P)

Unformatted text preview: 2) ATP decreases the concentration of pyruvate; high amounts of ATP means that there is excess energy and need to stop catabolism 3) AMP increases the concentration of pyruvate; low amounts ATP and thus a need for more energy 4) Fructose-1,6-diphosphatase promotes the conversion of Fructose-1,-6-diphosphate back into Fructose-6-phosphate and ultimately decreasing the concentration of pyruvate 5) Caffiene/epinephrine promotes the conversion of glycogen to glucose thus producing more pyruvate...
