Question
Chapter 2, Problem 29P
Interpretation Introduction
Interpretation:
A biochemical phenomenon needs to be proposed to jusitify the variety of symptoms displayed by osteogenesis imperfecta using the structure knowledge of the amino acid and collagen.
Concept introduction:
Amino acids are organic compounds containing amino as well as acidic groups. The general molecular formula of an amino acid is as follows:
Here, R refers to different groups of different amino acids. If there are more than one amino group present in an amino acid, they are considered as basic amino acids and if there are more than one carboxylic group, then they are considered as acidic amino acids.

Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below.
The above figures show the rate of actin polymerization in the presence of various concentration of profilin (Pfn). In the top figure, flourescence intensity is a measure of total actin that has been polymerized, and this is plotted versus time in seconds. The shade of blue of the lines in the top figure correspond to the shaded blue bars representing various concentrations of profilin in the lower figure. The lower graph shows the initial rates of polymerization of actin plotted again concentration. Which of the following is true:
Question 21 options:
profilin in a molecular motor
profilin is a promoter of actin polymerization
profilin replaced G-actin in an F-actin strand and breaks the filament
profilin is an inhibitor of actin polymerization
profilin binds to G-actin, preventing it from polymerizing
