Final answer:
The removal of peroxisomes would lead to a decrease in lipid metabolism and detoxification processes, and an increase in harmful reactive oxygen species.
Step-by-step explanation:
If all of the peroxisomes in a cell were suddenly removed, it would significantly affect the cell's immediate activity and function. Peroxisomes perform critical roles in lipid metabolism, detoxification of harmful substances, and the breakdown of fatty acids and amino acids. A particular consequence of this would be an increase in reactive oxygen species (ROS) since peroxisomes are involved in neutralizing these harmful compounds. Therefore, the sudden removal of peroxisomes from a cell would result in a decrease in lipid metabolism and detoxification processes, and an increase in the levels of reactive oxygen species, which could harm the cell and the organism.
