BIOL4004 WEEK 5 EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED LATEST UPDATE
TOM complex
This mitochondrial outer membrane translocator imports nearly all nucleus-encoded
proteins from the cytosol into the mitochondrial intermembrane space
Nucleoporins
Have eight-fold rotational symmetry and enable bidirectional transport between nucleus
and cytosol
Rough endoplasmic reticulum
Membranous tubules and sacs specialized for protein production and folding, have
ribosomes attached
Peroxisomes
Organelles that contain oxidative enzymes
Sec61
SRP receptor passes ribosomes to this translocator that provides a channel for the
emerging polypeptide to cross the membrane from the cytosol into the lumen of the ER
Topologically equivalent
Effectively continuous spaces; compartments through which material can transfer
without crossing a membrane
Scramblase
