Detailed explanation-1: -It also refers to the space between the inner and outer nuclear membranes of the nuclear envelope, but is often called the perinuclear space. The IMS of mitochondria plays a crucial role in coordinating a variety of cellular activities, such as regulation of respiration and metabolic functions.
Detailed explanation-2: -As the proton (H+ ion) moves down the concentration gradient this moves the enzyme in a spinning motion, which brings ADP and inorganic phosphate together to form a bond, thus creating ATP molecule. The resulting ATP molecule is released so that a new ADP molecule can enter for another phosphorylation.
Detailed explanation-3: -If there are more hydrogen ions in the intermembrane space, this means there are more hydrogen ions available to move through the channel of ATP synthase. This in turn means that there will be an increase in the number of ADP molecules being phosphorylated. Therefore, more ATP will be produced.
Detailed explanation-4: -Gradient-driven synthesis of ATP. As H +start superscript, plus, end superscript ions flow down their gradient and back into the matrix, they pass through an enzyme called ATP synthase, which harnesses the flow of protons to synthesize ATP.
