Which of the following answer choices best describes J. J. Thomson's plum-pudding model? An atom is surrounded by a firm outer shell and contains positively charged particles in its core.

A series of enzymes catalyze the reactions in the metabolic pathway X → Y → Z → A. Product A binds to the enzyme that converts X to Y at a position remote from its active site. This binding decreases the activity of the enzyme. What is substance X?
