Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A series of proteins that pass electrons from one to another, releasing energy.
A
ATP
B
Electron Transport Chain
C
NADPH
D
Chlorophyll
Explanation: 

Detailed explanation-1: -The ETC is a collection of proteins bound to the inner mitochondrial membrane and organic molecules, which electrons pass through in a series of redox reactions, and release energy. The energy released forms a proton gradient, which is used in chemiosmosis to make a large amount of ATP by the protein ATP-synthase.

Detailed explanation-2: -The electron transport chain and ATP synthase are embedded in the inner mitochondrial membrane. NADH and FADH2 made in the citric acid cycle (in the mitochondrial matrix) deposit their electrons into the electron transport chain at complexes I and II, respectively.

Detailed explanation-3: -The FADH2 and NADH molecules produced in glycolysis and the Krebs Cycle, donate high-energy electrons to energy carrier molecules within the membrane.
