Final answer:
To approximate the number of photons absorbed per second by a GFP molecule, you can use the formula: Number of photons absorbed per second = Power of source (in watts) / Energy per photon (in joules).
Step-by-step explanation:
The number of photons a GFP molecule absorbs per second can vary depending on various factors such as the intensity of light and the concentration of GFP molecules.
However, to approximate the number of photons absorbed per second, we can use the formula:
Number of photons absorbed per second = Power of source (in watts) / Energy per photon (in joules)
Assuming a GFP molecule absorbs a photon with an energy of 2.48 eV, we can convert it to joules and calculate the number of photons absorbed per second using the given power of the light source.
