What is the role of the pH in the mitochondrial matrix and intermembrane space in cellular respiration?
The pH in the mitochondrial matrix and intermembrane space plays a crucial role in cellular respiration by regulating the activity of enzymes involved in the process. Maintaining the appropriate pH levels ensures optimal functioning of the electron transport chain and ATP production.
What else can I help you with?
What 2 cell parts does cellular respiration take place?
mithochondrial matrix and thylakoid or... (apex answer---->)mitochondrial matrix and cristae :) <3 kymmie.. apex all the way :)
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 are the directions of hydrogen flow during synthesis of ATP?
During the synthesis of ATP, the flow of hydrogen ions (protons) is from the intermembrane space through the ATP synthase complex into the mitochondrial matrix. This movement of hydrogen ions creates a proton gradient that drives the synthesis of ATP from ADP and inorganic phosphate.
Where does the Krebs cycle occur in humans?
The Krebs cycle, also known as the citric acid cycle, occurs in the mitochondrial matrix of human cells. This cycle is an important part of cellular respiration where acetyl CoA is oxidized to generate energy in the form of ATP.
Where in the cell does the Krebs cycle part of cellular respiration occur?
The Krebs cycle, also known as the citric acid cycle, occurs in the mitochondrial matrix of eukaryotic cells. This cycle is an important step in cellular respiration, where acetyl-CoA is oxidized to produce ATP, NADH, and FADH2.
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
During cellular respiration acetyl coA accumulates in what location?
mitochondrial matrix
What causes an area of the inner membrane to become positively charged?
An area of the inner mitochondrial membrane becomes positively charged as a result of the electron transport chain process during cellular respiration. During this process, protons are pumped across the inner membrane, creating an electrochemical gradient with a higher concentration of protons in the intermembrane space compared to the mitochondrial matrix. This results in a positively charged intermembrane space and a negatively charged matrix.
How do protons into the intermembrane space of the mitochondria?
Protons are pumped into the intermembrane space of the mitochondria during cellular respiration, specifically through the activity of the electron transport chain (ETC). As electrons are transferred through a series of protein complexes (I, II, III, and IV) in the inner mitochondrial membrane, their energy is used to actively transport protons from the mitochondrial matrix into the intermembrane space. This creates a proton gradient, which is essential for ATP synthesis, as protons flow back into the matrix through ATP synthase, driving the conversion of ADP to ATP.

Which of the following correctly matches the phase of cellular respiration with its location in the cell?
Pyruvate dehydrogenase complex . . . mitochondrial matrix
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.
Where is the electron transport chain in cellular respiration located?
The electron transport chain in cellular respiration is located in the inner mitochondrial membrane of eukaryotic cells and the plasma membrane of prokaryotic cells.
Where does the first electron carrier pump hydrogen ions?
The first electron carrier that pumps hydrogen ions during cellular respiration is NADH dehydrogenase (complex I) in the electron transport chain. It pumps hydrogen ions across the inner mitochondrial membrane from the matrix to the intermembrane space.
What energy-producing process takes place in the mitochondria?
The electron transport chain uses energetic electrons to pump protons into the mitochondrial intermembrane space. The chemiosmotic process involving ATP synthase makes ATPs by taking advantage of the tendency of the protons to return to the mitochondrial matrix.
What is the space in the middle of mitochodrion called?
The space in the middle of a mitochondrion is called the mitochondrial matrix. It contains enzymes involved in the Krebs cycle, as well as mitochondrial DNA and ribosomes. The matrix plays a crucial role in energy production through cellular respiration.
Where does the Krebs cycle occur in humans?
The Krebs cycle, also known as the citric acid cycle, occurs in the mitochondrial matrix of human cells. This cycle is an important part of cellular respiration where acetyl CoA is oxidized to generate energy in the form of ATP.
