6- endoplasmic reticulum and Golgi apperatus Flashcards
endoplasmic reticulum
interconnected network of tubes, vesicles an cisternae
function of endoplasmic reticulum
•protein translation •folding and transport proteins
the proteins formed can be used or…
•used in the cell membrane •secreted from the cell- digestive enzymes •sequestion of calcium
3 types of ER
- Rough endoplasmic reticulum
- Smooth ER
- sarcoplasmic reticulum
RER
•surface is studded with ribosomes •ribosomes can detach to make SER •membrane continues with the outer layer of the nuclear envelop •membrane bound vesicles shuttle proteins from RER to Golgi apparatus •riboosomes bind once proteins destined or sorting sythesis
SER
•diff functions in animals & plants •synthesis of lipids and steroids •metabolised of carbohydrates •regulations pf calcium conc •drug detoxification •connected to nuclear envelope •increases SA
SER in the liver
•glucose-6-phospate converts to glucose in gluconeogemesis •glucose to be formed from glycogen and released into blood
SER and detoxification
phase 1- oxidation, reduction and hydrolysis
phase 2- methylation, suffocation and amino acid conjunction - waste via gall bladder and kidneys
