The lysosome
Where do peroxisomal protein fold before exiting the cell organelle?
Cytosol
Where are proteins transported from ER during protein maturation?
In Cis-Golgi
During in-vivo motility assays
Myosin molecules under glass
The researchers identified the complex process of protein secretion on
The pancreatic exocrine cells
During the 1st phase of actin polymerisation -
ATP bind to G-actin monomers
These monomers aggregate until a stable nucleus is formed
Which molecule is located primarily in the A band of the myofibril?
Myosin
Which part of the neurone synthesises the vast majority of proteins and membrane?

Hanson and Huxley
Which is a WBC surface protein?
PAF receptor
Integrins
(Oligosaccharides)
Which cell organelle is the site of FA and AA oxidation?
The peroxisome
Where do newly translated membrane proteins fold?
In the lumen of the rough ER
From where are the vesicles transported to lysosomes?
Trans-Golgi
Which cell organelle produces a large amount of hydrogen peroxide?
The peroxisome
A weak adhesion is formed between leukocytes and endothelial cells
P-selectin molecules + Oligosaccharides
Where is neurotransmission carried out?
Axon terminals
What is the difference between the synthesis of secreted and membrane bound-proteins?
Signal peptide (is not cut at the end)
What is the basic method of fractionation?
Cells are broken open, and the cellular components are separated on the basis of size, mass, and density using a variety of centrifugation techniques
Fast axonal transport was characterised by observing the movement of:
Observing vesicles of the smooth ER
Who received the Nobel price for medicine and physiology in recognition of his pioneering work?
Christian de Duve
Extravesation requires special structures on the WBC surface. Which is such a WBC structure?
PAF receptors
Integrins
Where is the translocon located?
Between the ER and the Golgi
How do the small lamellipod move in extension stage during cell motility?
By actin and myosin adhesion
Where do perioxsomal proteins fold before entering the organelle?
Cytosol
