27. Hydrolysis of ________in an actin filament reduces the strength of binding between the monomersand _________the stability of the polymers
A.ATP, decreases
B.GTP,decreases
C.ATP, increases
D.GTP, increases
G-actin is a globular protein. But G- actin monomers polymerize to form polymer F-actin. An F-actin polymer is fibrous because of the number of monomers joined to form a polymer. Each G-actin protein has active sites for attachment to the cross bridges originating from primary myosin filaments.
Hydrolysis of ATP in to ADP reduces the strength between monomers and decreases the stability of the polymer.
OPtion 'A' is the right one.

The balance between the association of actin monomers to form a filament and dissociation of monomers from the actin filament is a Myosin independent b. Myosin dependent c. ATP independent d.ATP dependent e. charge dependent QUESTION 2 Which statement about actin is correct? a Actin is expressed only in muscle b. Actin is expressed at low levels in most cells. GNo known function has been described for actin in nonmuscle cells. d. Nonmuscle cells only contain G...
Show the relationship between sacomere, thin filament, thick filament, actin, myosin, A bands, I bands, M lines and Z discs.
According to the sliding filament model, binding sites on actin open when _, allowing the myosin head to bind. calcium ion levels fall creatine phosphate levels rise myosin levels rise calcium ion levels rise ATP levels rise Question 5 2 pts If cardiac muscle cells were prevented from undergoing aerobic metabolism, they ultimately would stop contracting undergo glycolysis synthesize ATP start contracting not be affected
Activity 27-3. Nuclear binding energy [Accompanies
Section 27-3]
The energy that would be required to separate a nucleus
into its individual nucleons is called the binding energy EB. The
graph shows the binding energy per nucleon EB/A versus mass number
A.
For each of the following processes in which nuclei are
combined to make a larger one, state whether the process releases
energy or requires an input of energy, and explain your
reasoning.

1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
