Question

After glycolysis, pyruvate oxidation, and the citric acid cycle, glucose has been completely oxidized into CO2 Very little of the energy released by glucose oxidation has been used to make ATP so far. The remaining energy has been transferred to electron carriers. To harvest this energy, electrons must be released from these carriers and flow through a seri This process requires a very electronegative molecule that can accept matrix enzymes ATP synthases membrane-associated proteins ow-energy elect The electron transport chain The following image depicts the events that occur within the electron transport chain. Match each label with its corresponding letter (A through L) in the diagram. (Note: You will not use all letters.) DOLL so FGH KL

Explanation / Answer

Hi,

The answer: membrane associated proteins.

The mitochondria are called the power house of the cell. Many energy rich reactions take place inside the mitochondria and high energy electrons are generated. An example of such reaction is Kreb’s cycle. These electrons now enter the mitochondrial membrane. Here many intra-membrane proteins are situated. These electrons enter these proteins sequentially and generate proton motive force. This force is used to produce ATP in ATP synthase enzyme. Example of these proteins are ubiquitinase complex.
