Life Under Hydrostatic Pressure Flashcards
1
Q
How do you calculate pressure?
A
Pressure = 0.1 x Depth (m) x Atmospheric Pressure.
2
Q
How can large pressure variations lead to alterations at various levels of cell growth?
A
Molecules: protein complexes & lipid bilayers.
Cells: membrane fluidity, intra-cellular pH, cytoskeleton, protein synthesis.
Organism: abnormal cleavage in larval development, paralysis, hyperactivity, spasms, loss of coordination/equilibrium.
