AA channel protein spanning the plasma membrane
BA series of linked reactions converting substrate to product
CA single reaction that releases all of a molecule's energy
DA gradient of hydrogen ions across a membrane
Answer & Solution
Correct answer: B. A series of linked reactions converting substrate to product
1. A metabolic pathway is a series of interconnected biochemical reactions.
2. It converts a substrate molecule or molecules step by step through a series of metabolic intermediates.
3. The pathway eventually yields a final product or products.
4. Because it proceeds stepwise, no single reaction releases all of a molecule's stored energy at once.
