Answer #1

1. Option a is correct

ATP hydrolysis is necessary for the depolymerization of ADP- actin from the filament (negative end ).

If ATP doesnot gets hydrolysed then no depolymerization so filament will grow longer.

2. Option b is correct .

When myosin is tethered to a glass slide and then actin is added then the force of movement is provided by myosin.

Myosin head move towards plus end of filament. So the filament is gliding towards its minus end.

    1. If you add short actin filaments marked by bound myosin heads (myosin-decorated filaments) to a solution with an excess of actin monomers, wait for a few minutes, and then examine the filaments by electron microscopy, you see the picture shown in Figure 16-5. A. Which is the plus end of the myosin-decorated filaments and which is the minus end? Which is the "barbed" end and which is the "pointed" end? How can you tell? B. If you diluted the...

    You have added a pure solution of formin to a solution of actin in ionic conditions appropriate for actin polymerization (i.e. 100 mM K+, 2 mM Mg2+, and 1 mM ATP). What do you predict occurs to the rate of actin filament assembly? o The rate of actin filament assembly increases only on the plus ends of the actin filaments, on the minus end it is unchanged. The rate of actin filament assembly is unchanged at the minus end and...

    please answer all that you can 1. You have genetically engineered green fluorescent protein (GFP) containing a KDEL sequence (GFP-KDEL). When GFP-KDEL is expressed in normal human fibroblasts and examined using fluorescence microscopy, the fluorescence appears diffuse across the cytoplasm. How would you explain this observations given that KDEL is supposed to be an ER-specific sorting sequence? A. This engineered GFP would not have a hydrophobic signal sequence to get it into the RER in the first place. B. The...
