Describe the photoactivation of chlorophyll
Did you know?
WebTwo electrons in the primary pigment molecule (ie. the chlorophyll molecule) are excited to a higher energy level and are emitted from the chlorophyll molecule in a process known as photoionisation Each excited electron is passed down a chain of electron carriers known as an electron transport chain, before being passed on to photosystem 1 WebPhotoactivation, the activation of the latent oxygen-evolving activity by light, is a phenomenon widely observed for various photosynthetic organisms from blue-green algae to higher plants (1–4). One of the conspicuous characteristics of this process is that it is a multi-quantum process (5–7).
