Question
The type II (“2”) form of this cellular process, which can only occur in Gram-negative bacteria, is facilitated by proteins known as GSPs. For 10 points each:
[10e] Name this process of exporting molecules from a cell. This process is more colloquially associated with releasing endocrine hormones into the bloodstream.
ANSWER: secretion [or descriptions include the word secrete or secreting; accept hormone secretion; accept general secretory proteins]
[10m] Exo·proteins destined to leave a Gram-negative bacterial cell via type II (“2”) secretion must first be transported into this location, the space between its inner and outer membranes.
ANSWER: periplasm [or periplasmic space]
[10h] P. carotovorum (“KAY-roe-toe-vore-uhm”), a pathogen once part of the Erwinia genus, uses the type II (“2”) secretion system to export factors that break down these molecules. These polymers are primarily composed of galacturonic (“GAH-lack-TIER-ah-nick”) acid chains.
ANSWER: pectins [accept pectinases; accept Pectobacterium carotovorum; accept Pectobacteriaceae]
