Two protons are translocated across the inner mitochondrial membrane by complex iv for every pair of electrons passing through the electron transport chain.
<h3>What is
inner mitochondrial membrane?</h3>
- The mitochondrial membrane that divides the intermembrane gap from the mitochondrial matrix is known as the inner mitochondrial membrane (IMM).
- As a result, the inner mitochondrial membrane maintains the proton gradient that powers oxidative phosphorylation and serves as a functional barrier to the passage of tiny molecules between the cytosol and the matrix.
- Cristae are the name for the inner membrane folding of mitochondria.
- They broaden the surface.
- The inner or cytoplasmic membrane controls the flow of nutrients, metabolites, macromolecules, and information into and out of the cytoplasm and preserves the proton motive force necessary for energy storage.
- It is impermeable to polar molecules.
- The inner membrane of E is connected to more than 100 distinct proteins.
- Similar to the cell membrane, the mitochondrial inner membrane is mostly composed of a phospholipid bilayer.
- Several proteins that function to carry out the electron transport chain are embedded in this bilayer.
- The membrane's surface area is increased by folds called christae.

Explanation:
The endomembrane system (endo- = “within”) is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins. It includes a variety of organelles, such as the nuclear envelope and lysosomes, which you may already know, and the endoplasmic reticulum and Golgi apparatus, which we will cover shortly.
Although it's not technically inside the cell, the plasma membrane is also part of the endomembrane system. As we'll see, the plasma membrane interacts with the other endomembrane organelles, and it's the site where secreted proteins (like the pancreatic enzymes in the intro) are exported. Important note: the endomembrane system does not include mitochondria, chloroplasts, or peroxisomes.
Let's take a closer look at the different parts of the endomembrane system and how they function in the shipping of proteins and lipids.

Answer:
Both aneuploidies and trisomies are the result of nondisjunction of the homologous chromosomes during meiosis. The error in the mechanism of chromosome segregation produces two daughter cells, one of them with two homologous chromosomes and the other one without
