-ايش Feedback inhibition
-وش الفرق بين Exocytosis , endergonic , exergonic , signal transport ,
وفي أسالة في الموقع الاحياء ماعرفت لها ..
- exergonic reaction:
1/exothermic ,
2/make complex molecules from simpler ones
3/ occur only in autotrophs
4/occur only in heterotrophs
^ heterotrophs و ايش يعني exothermic
-towards the end of active transport the .... group detaches and the transport protein returns to its original shape :
1\ADP
2\ATP
3\amino
4\phosphate
5\hydroxyl
ـــــــــــــــــــــــــــــــــــــــــــــــــ
-endocytosis is a process that is opposite to ـــــــــــــــ
1\ectosytosis
2\parasitosis
3\exocytosis
4\mesocytosis
5\all of rhe above choieces are correct .
ـــــــــــــــــــــ
-potential energy is ــــــــenergy
1\moving
2\stored
3\static
4\electrical
5\mechanical
ـــــــــــــــ
catabolic processes :
1\make complex molecules from simpler ones
2\break complex molecules into simpler ones
3/ occur only in autotrophs
4/occur only in heterotrophs
5\none of the above
ـــــــــــــــــــــ
wich of the following is not true of the plasma membrane ?
1\contains receptors for the communication
2\forms intercellular connection
3\is a rigid sheet of molecules with little flexibility .
4\regulates material movement into and out of the cell
5\ is made of phospholipids bilayer
^اختار هنا 3 ليش ؟!
ــــــــــــــــــــــــــــــــــ
ـــــــــــis a form of kinetic energy associated with random movemet of molecules
1\ evapaoration
2\thermal energy
3\heat
4\ transformation
5\B and C are correct choices .
ــــــــــــــــــ
lactose binds to the ــــــــــ of lactase
1\ lactic side
2\saccheride site
3\active site
4\reactive site
5\enzymatic site
ـــــــــــــــــــــــ
fluid = liquid ?
