A scientist claims that the acceleration factor of Enzyme B is dependent on both enzyme and substrate concentration. Do the data in Fig 3 and 4 support her claim?

• No: the acceleration factor is dependent on enzyme concentration, but not on substrate concentration

• No: the acceleration factor is not dependent on either enzyme or substrate concentration

• Yes: the acceleration factor is dependent on enzyme concentration, but not on substrate concentration

• Yes: the acceleration factor is dependent on both the enzyme and the substrate concentration
