Upon absorption of a photon, a chlorophyll molecule gets converted to its excited state when the energy of the photon is
more than the ground state of the pigment molecule.
equal to that of the pigment molecule's excited state.
more than that of the ground state but less than that of the excited state of the pigment molecule.
equal to the energy gap between ground state energy and the excited state energy.
Answers (1)
When a chlorophyll molecule absorbs a photon, it can be promoted to an excited state. The energy required to promote the chlorophyll molecule from its ground state to the excited state corresponds to the energy gap between these two states.
Chlorophyll molecules are responsible for capturing light energy during photosynthesis. They are found in the chloroplasts of plant cells and are key pigments involved in the absorption of light for the conversion of light energy into chemical energy.
When a photon with an energy level matching the energy gap between the ground state and excited state of the chlorophyll molecule is absorbed, the chlorophyll molecule gains energy and transitions to an excited state. This energy can be used to initiate various biochemical reactions involved in photosynthesis, such as the transfer of electrons and the synthesis of energy-rich molecules like ATP and NADPH. Hence, the correct answer is option 4.
