What is the role of the pH of the mitochondrial intermembrane space in cellular respiration?
The pH of the mitochondrial intermembrane space plays a crucial role in cellular respiration by helping to create a proton gradient that drives the production of ATP, the cell's main energy source. This gradient is essential for the functioning of the electron transport chain and ATP synthase, key components of the respiration process.

What stage of aerobic cellular respiration pumps hydrogen into the intermembrane compartment?
The stage of aerobic cellular respiration that pumps hydrogen ions into the intermembrane compartment is the electron transport chain (ETC). During this stage, electrons are transferred through a series of protein complexes, leading to the active transport of hydrogen ions from the mitochondrial matrix into the intermembrane space. This creates a proton gradient, which is essential for ATP synthesis during chemiosmosis.

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.
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.

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.
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 excited electrons pump what ion to create a gradient?
Excited electrons in the electron transport chain of cellular respiration pump protons (H⁺ ions) across the inner mitochondrial membrane. This process creates a proton gradient, with a higher concentration of protons in the intermembrane space compared to the mitochondrial matrix. This electrochemical gradient is then used by ATP synthase to produce ATP during oxidative phosphorylation.
