An actin-binding protein called cofilin binds preferentially to ADP-containing actin filaments rather than ATP-containing actin

filaments. Based on this preference, which is true? Question 7 options: Cofilin binds to the plus ends of treadmilling actin filaments. Cofilin competes with profilin for binding to actin. Cofilin binds to older actin filaments. Cofilin binds to the plus ends of actin filaments.

Answer:

Cofilin binds to older actin filaments

Explanation:

Microfilaments (also called actin filaments) are a class of protein filament common to all eukaryotic cells, which consist of two strands of subunits of the protein actin. Microfilaments form part of the cell's cytoskeleton and interact with the protein myosin in order to allow the movement of the cell. Within the cell, actin may show two different forms: monomeric G-actin and polymeric F-actin filaments. Microfilaments provide shape to the cell because these filaments can depolymerize (disassemble) and polymerize (assembly) quickly, thereby allowing the cell to change its shape. During the polymerization process, the ATP that is bound to G-actin is hydrolyzed to ADP, which is bound to F-actin. ATP-actin subunits are present at the barbed ends of the filaments, and cleavage of the ATP molecules produces highly stable filaments bound to ADP. In consequence, it is expected that cofilin binds preferentially to highly stable (older) filaments ADP-actin filaments instead of ATP-actin filaments.

Nookie1986 [14]

It will have no effect because the order in which ingredients are mixed will not change the fact that matter cannot be created nor destroyed.

<h3>Effect occurs on mass</h3>

The order in which we add the ingredients do not affect the mass of the batter because the order in which ingredients are mixed will not change the fact that matter cannot be created nor destroyed.

The mass of the batter remains the same due to the incorporation of same quantity of ingredients so we can conclude that option A is the right answer for this question.

What dies survivor ship curve mean? What an easy way to remember what it means?
vredina [299]
Survivorship curve = so, first of all, it's a curve, as in a graph.

It describes "survivorship" - the rate of survival, in other words: out of 100 organisms that are born, how many survive. This rate is different among species, for example, most humans live out to most of their life span, and almost all can survive well beyond a reproductive age.

However, in frogs for example, many many individuals are born, but only few can survive to adulthood: most die very young, before reproductive age.

So if you hear about a new species: let's say dogs, and you want to know how long they would live, you would look at their sirvivorship curve (and in some breeds of dogs, those that are likely not to be in shelters, but in homes, the survivorship curve would be similar as in humans: almost all individuals born can live long.
