Question

match the words in the left column to the appropriate blanks in the sentences on the right. show instructions 1. both phosphofructokinase and isocitrate dehydrogenase are regulated by feedback, where the product of the reaction or series of reactions the enzyme activity. they differ in that phosphofructokinase is regulated by while isocitrate dehydrogenase is controlled by competitive activation inhibits activation allosteric inhibition inhibition allosteric activation competitive inhibition activates

Explanation:

Feedback regulation can be inhibitory or activating. In feedback inhibition, the product of a reaction inhibits the enzyme's activity. Phosphofructokinase is often regulated by allosteric inhibition and isocitrate dehydrogenase can be regulated by allosteric activation.

Answer:

1. inhibition; inhibits; allosteric inhibition; allosteric activation
