Cell Respiration - ETC + Chemiosmosis

Question 1

What is the function of ETC?

Answer 1

transfer electrons through a series of protein complexes embedded in the membrane

Question 2

What is the location of the ETC?

Answer 2

located in the inner mitochondrial membrane

Question 3

What is the electron movement in ETC?

Answer 3

move through protein complexes in a series of redox reactions, releasing energy at each step

Question 4

What is pumped during the ETC?

Answer 4

as electrons move through the ETC, protons are pumped across the inner mitochondrial (against concentration into the intermembrane space)

Question 5

What is chemiosmosis?

Answer 5

the gradient that was created by the pumping of the protons is used to drive ATP synthesis, protons flow back into the mitochondrial matrix through ATP synthase; this is coupled with the synthesis of ATP from ADP and an inorganic phosphate

Question 6

What electron acceptor transfer their electrons to complex 1 and 2?

Answer 6

NADH, FADH2

Question 7

Where do the electrons transfer to?

Answer 7

oxygen, combines with electrons and protons to make water
