inner membrane in mitochondria

Mitochondria are tiny structures that occur in varying shapes cylindrical, spherical, oval, rod shaped etc. They are found distributed all over the cytoplasm. fig. 16.6 - Mitochondria Each mitochondrion is bound by a double membrane. The outer membrane is smo..

These may be cylindrical, rod-shaped or spherical and distributed in the cytoplasm. Each mitochondrion is bound by a double membrane. The inner membrane is folded into ridges called cristae, which increase the surface area of the membrane...

It is present in both plant and animal cells. It is living, elastic and made of proteins and lipids (fats). Its function is to provide a mechanical barrier for the protection of the inner cell contents and to regulate the movement of molecules in and out of the cel..

Unit Membrane Concept - The molecular structure of cell membrane is still not clearly known. Several models have been proposed from time to time to explain its structure based on its physico-chemical properties. In the year 1935 Danielli and Dawson proposed that the cell me..

Ribosomes are granule-like structures found in both prokaryotic and eukaryotic cells. They are found distributed all over the cytoplasm. In a eukaryotic cell ribosomes occur freely in the cytoplasm, attached to the surface of branches of endoplasmic reticulum (RER), in the matrix of organelle..

Electron Transport System - The metabolic pathway through which the electron passes from one carrier to another, is called the electron transport system. Electron Transport System (ETS) in Mitochondrion The electron transport system occurs in the inner membrane of the mitoc..

) or secretory products (gums, alkaloids, hormones, etc) or excretory products (calcium carbonate and other salts). These substances are generally stored in the vacuoles. Cell organelles are mainly of two types membrane-bound and non-membranous. Membrane bound organell..

>. The reduced coenzymes are regenerated in the electron transport chain. The electron transport enzymes of the inner mito chondrial membrane transport the electrons in an ordered sequence to molecular oxygen ultimately producing H 2 O. Simultaneously these enzymes transfer prot..

It is the air-filled cavity inner to the ear drum, tympanum. It is separated from the inner ear by a partition with two membrane-bound apertures. The upper aperture is oval and is called fenestra ovalis (oval window). The lower one is round and called the fenestra rot..

Each cell can be regarded as a compartment by itself since it is bound on all the sides by a cell membrane. It separates the protoplasm within the cell from the surrounding environment. As a result, the cell is able to retain specific molecules and carry out certain reactions in an orderl..
