Secretion & Endocytosis

Question 1

The ??? system describes chemical and metabolic processes within a eukaryotic cell being compartmentalised E.g. glucose formation will occur distinctly to glucose breakdown elsewhere

Answer 1

endomembrane

Question 2

Endocystosis or exocytosis (?) is in charge of delivery of newly synthesised material to the plasma membrane or the extracellular space

Answer 2

exocytosis

Question 3

Endocystosis or exocytosis (?) is in charge of capturing extracellular molecules by removing / recycling plasma membrane components and delivering them to endosomes or lysosomes

Answer 3

endocytosis

Question 4

Vesicles are carried by ??? proteins which move along ‘tracks’ of microtubules of the cytoskeleton

Answer 4

motor

Question 5

What is the primary site of glycans synthesis and attachment to proteins and lipids (Glycan labels direct specific proteins towards certain fates)?

Answer 5

Golgi apparatus

Question 6

Glycosylation is an important post-translational modification of proteins and N-linked glycosylation is common in eukaryotes or prokaryotes (?)

Answer 6

eukaryotes

Question 7

N-linked glycosylation: Oligosaccharides are attached to asparagine starting with high-mannose glycans in ER. Complexity continues in ???

Answer 7

Golgi

Question 8

glycosylation at the Golig plays important roles in protein maturation by improving solubility, mediating binding to chaperone proteins, and providing resistance against ??? enzymes

Answer 8

proteolytic

Question 9

these are the characteristics for what organelle in a cell?
- Acidic pH (~4.5 – 5) is optimal pH for hydrolytic enzymes
— Enzymes: nucleases, lipidases, proteases, glycosidases
— Production can be upregulated as needed
— Targeted to lysosome via M6P tag by Golgi

Answer 9

lysosomes
