Rough and Smooth ER and Golgi Apparatus

NOT FINISHED - CATCH UP AT HOME WITH PICTURES FOR GOLGI

What is the function of the Rough ER

It synthesizes proteins using ribosomes, folds and modifies them and packages them for transport

What is the function of the Smooth ER

It creates lipids and cholestrol, detoxifies chemicals, stores calcium ions and helps to break down carbohydrates

What is the difference between the rough and smooth ER (3 bullet points)

• RER has ribosomes on its surface whilst SER has no ribosomes

• RER modifies and synthesizes proteins whilst SER modifies and synthesizes lipids, carbohydrates and steroids

• RER is continuous with the nuclear envelope whereas SER is throughout the cytoplasm

What type of ribosomes are present on the RER

80S

What is the function of the Golgi Apparatus

It modifies proteins and lipids, sorts and packages molecules into vesicles for transport and can also form lysosomes

What is this and the function of it

Cisternae - processes proteins and lipids, sorts and packages molecules and provides storage

What is this and the function of it

Vesicles - they transport molecules, store substances, release contents outside the cell and digest and recycle materials

What is this and the function of it

Lysosome - digests waste and debris, recycles cellular components, defends against pathogens and releases digestive enzymes
