1 Vesicular Transport III

2 N-linked glycosylation because sugar is added to N of asparagine. original precursor oligosaccharide added to most proteins in the ER

3 Oligosaccharide chains are processed in the Golgi common core complex high-mannose

4 Vesicular transport model

5 Cisternal Maturation Model

6

7 Lysosome interior is different from cytosol

8 Detection of acid phosphatase in lysosomes Small spheres may be vesicles delivering the enzyme from the Golgi Apparatus

9 Structure of oligosaccharide that directs lysosome enzyme to the lysosome

10

11

12 3 pathways to degradation in the lysosome

13 Autophagosome with mitochondrion and peroxisome

14

15 3 possible fates of receptor proteins in an epithelial cell

16

17 Phagocyte ingesting chemically altered red blood cells

18 A neutrophil phagocytosing a bacterium

19 Formation of clathrin coated membrane from the plasma membrane

20

21 Caveolae in the plasma membrane of a fibroblast

22

23 Low Density Lipoprotein particle transports cholesterol in the blood 1500 cholesterol molecules esterified to long chain fatty acids in one particle

24 Normal LDL receptors facilitate transport of cholesteryl esters in clathrin coated vesicles

25 Defective LDL receptor protein causes high levels of blood cholesterol and heart disease

26 cholesterol is released in lysosome

27 opiod receptor green transferin red
