Photosynthesis is a process that converts carbon dioxide into organic compounds, namely sugars, using energy from sunlight. Many plants and bacteria carry out photosynthetic reactions in organelles called chloroplasts, which contain the pigment chlorophyll. Chlorophyll absorbs sunlight and gives plants their characteristic green color.

a) Based on this knowledge, draw the absorption spectrum of chlorophyll in the visible light region.

b) In Photosystem II of the thylakoid membrane of chloroplasts, approximately 16.3 moles of photons must be absorbed by chlorophyll pigments in order to obtain enough energy to produce one molecule of glucose (C6H12O6). If the total energy necessary is 686 kcal, what wavelength (in nanometers) are the chlorophyll in Photosystem II absorbing at? (1 kcal = 4184 joules)

c) What will happen if photons of a wavelength of 692nm are shined on the chlorophyll?
