Final answer:
The proteins encoded by the genes of complex groups I to IV act in a pathway in a specific order, such as in glycolysis where they act as hexokinase, phosphoglucose isomerase, phosphofructokinase, and enzyme 4.
Step-by-step explanation:
The order in which the proteins encoded by the genes of complex groups I to IV act in a pathway can vary depending on the specific pathway and cellular context. However, I can provide an example of a pathway and the order in which the proteins might act. In glycolysis, which is a metabolic pathway involved in the breakdown of glucose, the proteins encoded by the genes of complex groups I to IV would act in the following order:
- Glycolysis starts with the enzyme hexokinase, encoded by a gene.
- The next protein in the pathway is phosphoglucose isomerase, encoded by another gene.
- After that, enzyme 3, phosphofructokinase, encoded by a gene, comes into play.
- Finally, the pathway continues with the action of enzyme 4, resulting in the production of pyruvate and ATP.
