WebThe protein is initially modified by the addition of branching carbohydrate chains in the rough ER; these chains are then trimmed back and replaced with other branching chains in the Golgi apparatus. The protein, with its final set of carbohydrate chains, is then transported to the plasma membrane in a transport vesicle. WebMembrane proteins have a wide variety of functions. Some allow a cell to respond to specific chemical signals from other cells, others are enzymes and some proteins are …
