POGIL Oxidative Phosphorylation Key Solution

Answers




Where is the electron transport chain located? - answerwithin the inner mitochondrial
membrane

In the electron transport chain, where is the highest concentration of hydrogen ions
located? - answerintermembrane space (between inner and outer membranes)

How do hydrogen ions reach the intermembrane space? - answerthey diffuse through
embedded protein channels via facilitated diffusion

Why is energy required to move the hydrogen ions across the membrane into the
intermembrane space? - answerthe ions are moving against their concentration
gradient, from low to high concentration

What molecules carry the high potential energy electrons used to pump hydrogen ions
across the inner mitochondrial membrane? - answerNADH and FADH2

Where did the electron acceptor molecules (NADH and FADH2) come from? -
answerthey're produced in glycolysis, the link reaction, and the Krebs cycle (link
reaction may be considered part of the Krebs cycle)

When electrons are released from the electron acceptor molecules, what else is
produced? - answerH+ ions

Is the release of an electron from an electron acceptor molecule oxidation or reduction?
- answeroxidation

What molecule is the final electron acceptor after the electron has moved through the
electron transport chain? - answeroxygen

What compound is formed as a final product of the electron transport chain? -
answerH2O

Is any ATP produced in the electron transport chain? - answerNo

Is any ATP used in the electron transport chain? - answerNo
