Document Summary
Endoplasmic reticulum: network of membrane enclosed sacs, site of protein production and folding. Cytoskeleton: gel like matrix provides structure to cells. Plasma membrane: organelle that protects the cell from the environment and control what comes in and out. Concepts: be able to describe, define and/or differentiate. Kinesis: proteins that move in anterograde (towards synape) dynein motor proteins: proteins that move in retrograde (towards cell body) How proteins are made start to finish: dna-rna-protein then folding. How many levels of structure can a protein have: 4. Defining characteristics of proteins/amino acids: r groups (cid:374)eu(cid:396)ofi(cid:271)(cid:396)illia(cid:396)y ta(cid:374)gles/pla(cid:395)ues: fou(cid:374)d i(cid:374) patie(cid:374)ts suffe(cid:396)i(cid:374)g f(cid:396)o(cid:373) alzhei(cid:373)e(cid:396)"s a(cid:374)d similarly found in patients who suffer from repetitive brain injury. Diffusion: process where ions move from high concentration to low facilitated diffusion: process were ions move from high to love concentration with the help of protein carrier molecules in the membrane. Passive transport: no atp, move with concentration gradient.
