ASCI 112 Lecture Notes - Lecture 7: Endoplasmic Reticulum, Cytosol, Phospholipid
Document Summary
Organelles of this system are related either through direct physical continuity or by the transfer of member segments as vesicles; ribosomes create proteins, and they get packaged and shipped out to do their job in the rest of the body . Consists of the: golgi apparatus (packages) (all have membranes that consist of the phospholipid bilayer) A continuous membrane that separates the internal space (cisternae) of the. As proteins are being made by the ribosome they thread into the cisternal space and fold into their proper conformation. Proteins made in the rough er will go to the golgi to be packaged for secretion. Synthesis of lipids, metabolism of carbohydrates, detoxification of drugs and toxins. Cells of organs that make lots of hormones (e. g. adrenals) have lots of smooth er. Important also in moving calcium in muscle tissue for muscular contraction. After synthesis in er, newly made molecules passed to golgi bodies.
