A graph that plots the rate at which CO₂ is converted to sugar versus the wavelength of light illuminating a leaf is called A) a Planck equation plot. B) an absorption spectrum. C) an enzyme kinetics plot. D) an electromagnetic spectrum. E) an action spectrum.

Question

Quizplus · Accepted Answer

An action spectrum plots the rate of a physiological process, such as photosynthesis, versus the wavelength of light illuminating a sample. In this case, the graph is specifically tracking the rate of conversion of CO₂ (presumably a molecule involved in photosynthesis) to sugar, making it an action spectrum. The other options (A, B, C, and D) are not correct, as they either do not refer specifically to the kind of graph described, or they refer to graphs that do not have a direct connection to photosynthesis.
