The Calvin cycle is a process that plants and algae use to turn carbon dioxide from the air into sugar, the food autotrophs need to grow. The electrons lost by cholorphyll molecules are gained by DCPIP and vice versa. The cyclic electron pathway begins when the PS I antenna complex absorbs solar energy. 2. • The electrons run down an electron transport chain consisting of plastoquinone, cytochrome complex and plastocyanin to P700. By converting the energy of sunlight to a usable form of potential chemical energy, photosynthesis is the ultimate source of metabolic energy for all biological systems. 3 phosphoglycerate, Regeneration,Carboxylation, Triose phosphate, Reduction, Ribulose, 1,5 biphosphate, C0 2, Sucrose. Electrons then move suddenly from donor to acceptor through an electron transport chain. 1. Plants depend on the Calvin cycle for energy and food.Other organisms, including herbivores, also depend on it indirectly because they depend on plants for food. The other pathway, non-cyclic photophosphorylation, is a two-stage process involving two different chlorophyll photosystems. This system is responsible for the photolysis of water and involves the evolution of molecular oxygen. More carbohydrate is produced during cyclic photophosphorylation than during noncyclic photophosphorylation. 6.8): It is a process of photophosphorylation in which an electron expelled by the excited photo Centre (PSI) is returned to it after passing through a series of electron carriers.

The correct sequence of events during noncyclic photophosphorylation is a) photosystem I -> photosystem II -> ATP production -> NADPH production b) photosystem II -> NADPH production -> photosystem I -> ATP production B. Non-cyclic photophosphorylation involves both Photosystem I and Photosystem II. Photophosphorylation is the process of transferring the energy from light into chemicals, particularly ATP. These two photosystems work in series, first PS II and the PS I. Photophosphorylation is of two types. The key to this energy transformation is a flow of electrons through the photosystems and other molecular com po~ nents built into the thylakoid membrane.
