Question

1. what is the name of the process occurring along the inner membrane of mitochondria that pumps protons (h+) into the intermembrane space to drive the synthesis of atp?

• electron transport chain
• anaerobic respiration
• glycolysis
• krebs cycle

Explanation:

The electron - transport chain occurs along the inner membrane of mitochondria. It pumps protons ($H^+$) into the intermembrane space to create a proton gradient that drives ATP synthesis. Anaerobic respiration occurs without oxygen and not related to this specific mitochondrial - inner - membrane process. Glycolysis occurs in the cytoplasm, not the mitochondrial inner membrane. The Krebs cycle occurs in the mitochondrial matrix, not the inner membrane for proton - pumping to drive ATP synthesis.

Answer:

A. electron transport chain
