Question

can anyone help please......
identify the role of changing concentration of ATP, ADP, hydrogen ions and other intermediates such as citrate in regulation of glycolysis.

Answer 1

well i can help u in querries better have a look to some videos i have a site
khanacademy.org

Answer 2

ATP inhibits phosphofructokinase & Pyruvatkinase
High concentration of hydrogen ions interferes with electroncarriers such as NAD+ which needs to accept electrons when Glyceraldehyde-3-phosphate is catalysed by Glyceraldehyde-3-phosphate dehydrogenase... etc

I gave you a few, you should be able to finish the rest with a similar way of thinking.
Best of luck.
