Question

in the chemiosmotic model, ions diffuse from the intermembrane space to the inner membrane space (matrix). as a result adp is converted to atp.
hydrogen
phosphate
chloride
calcium
multiple choice 10 points
in the electron transport chain reactions, when do the electrons have the highest potential energy?
as they combine with oxygen to form water.
as they enter the third embedded protein complex
as they leave nadh (or fadh).

Explanation:

In the chemiosmotic model, hydrogen ions ($H^+$) diffuse from the intermembrane space to the inner membrane space (matrix), driving ATP synthesis. In the electron transport chain, electrons have the highest potential energy when they leave NADH (or FADH) as they start their journey through the chain, losing energy step - by - step as they move through the protein complexes.

Answer:

For the first question: hydrogen.
For the second question: As they leave NADH (or FADH).
