Protein translocation and secretion overview

Question 1

can bacteria transport large molecules like proteins

Answer 1

no cannot transport them into cell eg proteins

Question 2

Why can’t large molecule enter the cell

Answer 2

PM and OM of gram -ive cells are barriers

Question 3

where are all proteins synthesized

Answer 3

cytoplasm

Question 4

are there systems to insert proteins into membrane, transport them into periplasm, or release them into cell

Answer 4

yes

Question 5

What is translocation

Answer 5

transport of protein into a membrane or into periplasm of gram -ive bacteria

Question 6

what is secretion

Answer 6

release of protein outside the cell

Question 7

what is exoenzymes

Answer 7

secreted proteins that fn outside the cell, hydrolyze large nutrients into smaller pieces that can be take up by cell

Question 8

what are some exoenzymes

Answer 8

proteases (proteins to aa) lipase (triglyceride to glycerol and 3 fa) cellulase (cellulose to glucose) amylase ( starch to glucose)
