Heat Stress
What do CAM plants do during heat stress |
desert plants tolerste high temps
-CAM plants: convert light hitting the leaves (normally leads to heatining) to olnger wavelength of light & radiate them. ex// cati survive during very high temp |

High temps
1. what does it do 2.What do plants require more of during high temps |
Affect enzyme function-->denaturing
fluditiy of bioligical membreanes *membranes require more need F.acids in order for mem. permeability to not be affected by ^ temp |
|
|
Heat shock Protiens
define them. folding unfolding??? chaperones??? |
protiens expressed in high extreme temperatures
play important role in folding and unfolding protiens to remediate plants. Theses pr-- chaperone other pr--. Act as a repair of misfolding protiens to plant damage during high temps |
|
|
ubiquiTIN
|
known to mark other pr--for:
PROTEOLYSIS - aID in restoring normal cellular function after exposure of high temp |
|
|
ubiquiTIN
|
- turning over damaged pr--
-aiding in movement of new pr-- into correct cell compartments |
