Match the following proteins (Column I) with their function (Column II). Which of the following is correct?
|
Column I |
Column II |
|
a. Profilin |
i. binds to the (+) end of an actin filament,
thereby inhibiting subunit addition or loss. |
|
b. Cofilin |
ii. blocks (−) ends, inhibits filament disassembly, to
stabilize filaments |
|
c. Thymosin-β4 |
iii. involved in actin treadmilling, but it binds
specifically to F-actin in which the subunits contain ADP |
|
d. Cap Z |
iv. binds ADP–G-actin and catalyzes the exchange of
ADP for ATP |
|
e. Tropomodulin |
v. binds to ATP–G-actin in such a way that it
inhibits addition of the actin subunit to either end of the filament. |

Organization of the protein complexes the photosystems I and II Are spatially separated in the thylakoid membrane, choose the correct arrangement of PSI and PSII on the membrane ;
a.) The PSI reaction centre and its associated antenna pigments and electron transfer proteins, as well as the coupling-factor enzyme that catalyzes the formation of ATP, are found almost exclusively in the stroma lamellae and at the edges of the grana lamellae
b.) The PSI reaction centre, along with its antenna chlorophylls and associated electron transport proteins, is located predominantly in the stromal lamellae
c.) The PSII reaction centre and its associated antenna pigments and electron transfer proteins, as well as the coupling-factor enzyme that catalyzes the formation of ATP, are found almost exclusively in the stroma lamellae and at the edges of the grana lamellae
d.) The PSII reaction centre, along with its antenna chlorophylls and associated electron transport proteins, is located predominantly in the grana lamellae
