Question 1

what is the importance of oxygen in cellular respiration

Answer 1

facilitates the movement of electrons down the electron transport chain in order to create an electrochemical gradient for the creation of ATP

Question 2

why is oxygen referred to as the “final electron receptor”

Answer 2

oxygen accepts the electrons after they have passed through the electron transport chain; oxygen has high electronegativity which pulls electrons towards it

Question 3

what would happen to the process of CR if an inhibitor were introduced? how would this affect human health and survival

Answer 3

this would result in uncoupling and can be detremental to ones health. a case being “luft syndrome” where a woman was not producing ATP due to uncoupling and her body temperature spiked due to the thermal heat energy being produced

Question 4

what happens when electron transport and ATP synthesis are uncoupled.

Answer 4

H+ goes into the matrix and produces thermal heat energy

Question 5

two examples of uncoupling

1 beneficial 1 harmful

Answer 5

• hibernation
• DNP drug

- drug used to lose weigh that resulted in uncoupling and it was banned
