Question

question 8
which of the following completes a false statement? the electron transport chain:
accepts electrons from nadh
is located in the inner mitochondrial membrane
actively pumps h* into the matrix
oxidizes fadh₂ to fad
reduces oxygen to water

Explanation:

The electron transport chain (ETC) is located in the inner mitochondrial membrane. It accepts electrons from NADH and oxidizes \(FADH_2\) to \(FAD\). At the end of the ETC, oxygen is reduced to water. However, the ETC actively pumps \(H^+\) out of the matrix (into the inter - membrane space), not into the matrix.

Answer:

"actively pumps \(H^+\) into the matrix" is the false statement.
