Actin-binding proteins bind to actin and can modify its properties. You investigated the effect of a protein (CapBD) on actin polymerization by measuring the kinetics of actin filament formation in the presence and the absence of CapBD protein. You obtained the following results shown in the diagram. Which of the following statements is most likely to be true? KINETICS OF ACTIN ASSEMBLY actin alone 7500 6 5000 Policies amount of polymerized actin (arbitrary mass units) actin + CapBD 2500 - ty 500 1000 ASUO time (seconds) Both reactions are in the growth phase of polymerization. The rate of polymerization in the "actin+CapBD" reaction is higher than in the "actin alone" reaction. urs Tutoring O CapBD caps both ends of the actin filament. toring None of the above Q Search
