Did you know?
WebIt is a process of photophosphorylation in which an electron expelled by the excited photo-centre is returned to it after passing through a series of electron carriers. It occurs under conditions of low light intensity, wavelength longer than 680 nm and when CO 2 fixation is inhibited. ADVERTISEMENTS: WebApr 9, 2024 · Photophosphorylation is the process in which light energy is used from photosynthesis to convert adenosine diphosphate (ADP) to adenosine triphosphate (ATP). It is the process in which the energy-rich ATP molecules are synthesized by the transfer of the phosphate group to the ADP molecule during the presence of sunlight.

WebYour Answer:Describe the energy transfer process relative to both ATP and ADP. ADP can take energy in the form of phosphate group. atp can contribute energy to the phosphate group. apd can be phosphorylated into atp whereas atp can be dephosphorylated. ATP has the energy (phosphate group) to donate while ADP can accept energy in the form of a ...
