5 Questions

Where does the respiratory chain occur in eukaryotic cells?

Inner mitochondrial membrane

What drives the pumping of protons across the inner mitochondrial membrane in the respiratory chain?

Transfer of electrons to molecular oxygen

What is the primary function of the respiratory chain?

To generate adenosine triphosphate (ATP)

Which process produces ATP from adenosine diphosphate (ADP) and inorganic phosphate (Pi) in the respiratory chain?

Oxidative phosphorylation

What is the role of ATP synthase in the respiratory chain?

To produce ATP from ADP and Pi

Study Notes

Respiratory Chain in Eukaryotic Cells

  • Occurs in the mitochondrial inner membrane

Mechanism of Proton Pumping

  • Driven by the energy released from the transfer of electrons through a series of electron transport chain complexes

Primary Function of the Respiratory Chain

  • Generates ATP (adenosine triphosphate) from the energy released from the electron transport chain

ATP Synthesis

  • ATP is produced from ADP (adenosine diphosphate) and inorganic phosphate (Pi) through the process of chemiosmosis
  • ATP synthase plays a crucial role in this process

Role of ATP Synthase

  • Catalyzes the phosphorylation of ADP to ATP using the energy generated from the proton gradient
