Explanation:
- Cytochrome c is a peripheral membrane protein
- Cytochrome oxidase is an integral membrane protein
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers -they function as transport proteins, membrane enzymes and receptors, and cell adhesion molecules .
Further Explanation:
Integral membrane proteins are embedded and fixed within the membrane and flow from the extracellular fluid to the cytoplasm, and sometimes contain hydrophobic side chains which interact with phospholipids within the membrane which helps to anchor them; they contain one or more domains which span the protein. Multipass integral proteins cross the membrane several times whereas single pass integral proteins cross only once
Perpheral or extrinsic don't have interactions with the membrane's hydrophobic core. These are bound via interactions with polar phospholipid heads or other integral proteins and may be modified by the addition of fatty acids and lipids. They primarily function in transmitting messenger signals, to form temporary associations with the cell membrane and freely move unto the extracellular or intracellular space.
These carry out facilitated diffusion is used for the transport of large molecules unable to cross the plasma membrane at will. However, passive diffusion, describes the movement of substances (small molecules and ions) across the membrane, along their concentration gradient.
