What protein complex in the inner mitochondrial membrane allows protons to return to the matrix?
The protein complex responsible for allowing protons to return to the matrix in the inner mitochondrial membrane is called ATP synthase. It uses the energy from the flowing protons to produce ATP, which is the main energy currency of the cell.
What is mitchells chemiosmotic hypothesis?
Mitchell's chemiosmotic hypothesis proposes that the energy needed for ATP synthesis in mitochondria is generated by the electrochemical gradient of protons across the inner mitochondrial membrane. This gradient is established by the pumping of protons out of the mitochondrial matrix during electron transport chain reactions. The protons then flow back into the matrix through ATP synthase, driving the production of ATP.
Uses high energy electrons to convert ADP and ATP?
This process is known as oxidative phosphorylation and occurs in the inner mitochondrial membrane. The high energy electrons are transferred along the electron transport chain, leading to the pumping of protons from the mitochondrial matrix into the intermembrane space. The flow of protons back into the matrix through ATP synthase drives the synthesis of ATP from ADP and inorganic phosphate.
What is the middle of the mitochondrion called?
mitochondrial matrix
Where does he Krebs cycle occur?
MITOCHONDRIA More specifically, the mitochondrial matrix.

How many protons are pumped out of the matrix when 2 electrons flow through the ETC complex?
For every pair of electrons that flow through the electron transport chain (ETC) complex, it results in the pumping of 2 protons out of the matrix. This proton pumping contributes to the establishment of an electrochemical gradient across the inner mitochondrial membrane, which is utilized to generate ATP through ATP synthase.

What is the middle of the mitochondrion called?
mitochondrial matrix
Which of the following processes involved in cellular respiration has a positive Gibbs Free energy?
The pumping of hydrogens from the mitochondrial matrix to the intermembrane space
If an uncoupler allows for excess buildup of protons inside of the mitochondrial matrix, which of the following processes will be inhibited?
None of these will be inhibited
Where does he Krebs cycle occur?
MITOCHONDRIA More specifically, the mitochondrial matrix.
What cellular compartment becomes acidic during mitochondrial electron transport?
The mitochondrial intermembrane space becomes acidic during mitochondrial electron transport due to the pumping of protons from the matrix across the inner membrane to the intermembrane space by complexes I, III, and IV of the electron transport chain. This forms an electrochemical gradient used to generate ATP through ATP synthase.
Where are the enzymes of the Krebs cycle located?
The enzymes of the Krebs cycle are located in the matrix of the mitochondria, which is the innermost compartment of the mitochondria where many cellular respiration processes take place. This is where the series of enzymatic reactions comprising the Krebs cycle occur, resulting in the production of ATP and other important molecules.
What happens in the mitochondrial matrix oxygen combined with?
In the mitochondrial matrix, oxygen combines with electrons and protons to form water in a process known as oxidative phosphorylation. This process occurs during the electron transport chain, where the energy generated is used to produce ATP, the cell's main energy source.
What is the inner space in mitochondria?
The inner space in mitochondria is called the mitochondrial matrix. It contains enzymes that are essential for the krebs cycle, as well as mitochondrial DNA and ribosomes used for protein synthesis. Additionally, the matrix has a high concentration of protons that generate the electrochemical gradient necessary for ATP production.
