PGAL f. oxygenWhat would be the consequences of actin filament assembly/disassembly if a mutation prevented actins ability to bing ATPWhat would be the consequence for actin filament assembly/disassembly if a mutation prevented actin’s ability to bind ATP? What would be the consequence if a mutation prevented actin’s ability to hydrolyze ATP?
- ATP within actin subunits is hydrolyzed after assembly into a filament but before disassembly from a filament. in theprocess of assembly into a filament. in the process of disassociation from a filament after disassociation from a filamentWhich of the following are differences between the assembly processes of intermediate filaments versus that of actin microfilaments? A. New subunits are added internally to the intermediate filament rather than at the ends B. Assembly requires GTP rather than ATP C. Intermediate filaments are assembled from multiple tetramers rather than from monomers. D. A and B E. A and C_________________________ is responsible for bringing ATP-actin to the _________ of microfilaments. In contrast, ____________________ is responsible for destabilizing the ________________ end of microfilaments. thymosin; pointed; cofilin; pointed profilin; barbed; cofilin; pointed cofilin; barbed; profilin; pointed formin; barbed; G actin; pointed
- Under certain stable concentration conditions, actin monomers in their ATP form will polymerize to form filaments that disperse again into free actin monomers over time. Explain.The sarcoplasmic reticulum Ca2+-ATPase, pumps 2 mol Ca2+ out of sarcomeres per mol ATP hydrolyzed. Given the following steady-state concentrations and a membrane potential of 67 mV (inside negative), calculate ΔG for the following active transport process at 37 ∘C and pH=7.4:2Ca2+(in)+ATP+H2O→2Ca2+(out)+ADP+Pi+H+Which of the following describes an F-actin microfilament? A flexible, helical filament composed of two strands assembled from G-actin 13 protofilaments composed of heterodimers with a hollow core a flexible filament composed of 13 interwoven protofilaments Eight tetramers twisted into a rope-like filament
- Rigor mortis (the stiffening of muscles fibers several hours after death) is directly due to the depletion of what energy source? This energy molecule is used to power a calcium pump that transports Ca2+ ions back into the endoplasmic reticulum where calcium ions are already at a high concentration.Thin and thick filament are organized into functional unit calledThe sarcoplasmic reticulum Ca2+-ATPase, pumps 2 mol Ca2+ out of sarcomeres per mol ATP hydrolyzed.(a) Given the following steady-state concentrations and a membrane potential of 65 mV (inside negative), calculate ΔG for the following activetransport process at 37 °C and pH = 7.4:2Ca2+(in) + ATP + H2O → 2Ca2+(out) + ADP + Pi + H+ATP = 2.6 mM, ADP = 210 μM, Pi = 5.1 mM, Ca2+(in) = 32 mM,Ca2+(out) = 2.2 mM(b) In active muscle the pH can drop below 7.4. Is the reaction above moreor less favorable under these conditions?(c) The activity of the Ca2+-ATPase is regulated reversibly under normalconditions to maintain homeostatic concentrations of Ca2+ inside thesarcomere. However, in a rare genetic disorder, irreversible activation ofthe Ca2+ -ATPase can occur. Assuming 37 °C, pH = 7.4, and the steadystate concentrations for ATP, ADP Pi, and Ca2 +(out) given in part (a),calculate the minimum [Ca2 +] inside a sarcomere that has irreversibly activated Ca2 +-ATPase (i.e., the Ca2 +-ATPase…
