Question

Give an example of a feed-forward reaction.

Answer 1

Feed-forward reaction:

1. The term "feed-forward" describes a reaction that reacts to changes in its environment in order to maintain the desired state.
2. The feed-forward activation method ensures that enzymes are serving in accordance with the overall goal of energy production.

Example:

1. Fructose1,6 bisphosphate activates pyruvate kinase, which is a good example of feed-forward activation.
2. Their own enzyme system regulates a glycolytic intermediate.
3. When glycolysis is activated, the activity of pyruvate kinase should likewise increase, allowing total carbon flow across the pathway.
