mitochondria and Plasma membrane

Question 1

Tom translocase

Answer 1

translocase of outer membrane

Question 2

Tim complex

Answer 2

translocase of inner membrane

Question 3

MPP

Answer 3

Matrix Processing Peptidase that cleaves targeting sequence following transport

Question 4

Tiny TIms

Answer 4

inter membrane space chaperones that carry proteins to Tim 22 channel complex.

Question 5

SAM

Answer 5

sorting and assembly machinery for moving some proteins from intermembrane space to outer membrane

Question 6

Plasma Membrane

Answer 6

defines the boundary of all cells (prokaryotic and eukaryotic) and separates the internal contents from the external environment surrounding the cell.

Question 7

How can peripheral membrane proteins disassociated for the plasma membrane?

Answer 7

with treatments of polar reagents such as solutions of extreme Ph or high salt concentration

Question 8

How can integral membrane protein

Answer 8

ampipathic detergents that disrupt the phospholipid biayer.

Question 9

Why is intestinal epithelial cells called Polarized?

Answer 9

a cell that has very different structural and functional faces at opposite ends of the cell.

Question 10

What molecules can freely diffuse across the plasma membrane?

Answer 10

Gases, hydrophobic molecules, charged molecules.

Question 11

Endocytosis

Answer 11

is a process in which material to be internalized is surrounded by an area of the plasma membrane, which then buds off inside the cell to form a vesicle containing the invested material.

Question 12

Pinocytosis

Answer 12

is the uptake of fluids or macromolecules in small vesicles.

Question 13

Phagocytosis

Answer 13

is the ingestion of large particles such as bacteria.
