The chemiosmotic gradient is due to
Understand the Problem
The question is asking about the cause of the chemiosmotic gradient in biological systems, specifically in the context of cellular respiration. It presents multiple options related to hydrogen ions and their movement, suggesting the user needs to identify which option correctly explains this gradient.
Answer
The pumping of hydrogen ions across the inner mitochondrial membrane.
The pumping of hydrogen ions across the inner mitochondrial membrane.
Answer for screen readers
The pumping of hydrogen ions across the inner mitochondrial membrane.
More Information
The chemiosmotic gradient is essential for ATP production. Protons are pumped by the electron transport chain, creating a concentration gradient that drives ATP synthesis.
Tips
A common mistake is to confuse the movement of protons through ATP synthase with the establishment of the gradient itself.
