In summary, the conjugated system of chlorophyll molecules helps with photon absorption because the equal distribution of electrons between double and single bonds makes it easier for photons to excite the electrons. The length of the conjugated system also plays a role, as shorter distances between bonds create more energy states, increasing the likelihood of photon absorption. This concept can be further understood by studying the particle in a box and how the spacing of energy states changes with the length of the box.

Homework Statement


Why does the conjugated system (alternance of single and double bonds) of chlorophylles help with photon absorption?

The Attempt at a Solution


Since two carbon atoms are equal in electric negativity, no one atom hogs the electrons. In this way, it is easier for photons to excite the electrons. However, I don't understand why single or double bonds would make a difference.

Thanks! [/B]

Think in terms of the "length" of the conjugated system.
 
  • #3
Double bonds make the molecule shorter than single bonds? How does that help with photon absorption?
 
  • #4
Of the SYSTEM of bonds (plural).
 
  • #5
Thanks! But how does that relate to photon absorption?
 
  • #6
Have you studied the particle in a box? How does the spacing of the energy states change when the length of the box changes?
 

1. What is a conjugated system of chlorophylls?

A conjugated system of chlorophylls refers to the arrangement of alternating single and double bonds in the chemical structure of chlorophyll molecules. This arrangement allows for the absorption of light energy, which is essential for photosynthesis in plants.

2. How does the conjugated system of chlorophylls contribute to photosynthesis?

The conjugated system of chlorophylls allows for the absorption of light energy in the visible spectrum, which is then converted into chemical energy that is used in the process of photosynthesis. Without this conjugated system, plants would not be able to absorb and utilize light energy for their survival.

3. Are all chlorophyll molecules part of a conjugated system?

No, not all chlorophyll molecules have a conjugated system. Chlorophyll a and b, which are the most common types found in plants, have a conjugated system, while chlorophyll c and d found in certain algae have a different chemical structure.

4. Can the conjugated system of chlorophylls be affected by environmental factors?

Yes, the conjugated system of chlorophylls can be influenced by various environmental factors such as light intensity, temperature, and nutrient availability. These factors can affect the absorption of light energy and therefore impact the overall efficiency of photosynthesis in plants.

5. Is the conjugated system of chlorophylls unique to plants?

No, the conjugated system of chlorophylls is not unique to plants. It is also found in other organisms such as algae and some photosynthetic bacteria. However, the specific types of chlorophyll and their arrangements may vary among different species.
