The Z scheme consists of 2 light reactions taking place in Photosystem I and Photosystem II, with electron transport components connecting these light reactions and additional electron transport components on the oxidizing side of one photosystem and the reducing side of the other photosystem. This cyclic electron flow generates a proton gradient for ATP formation from ADP and Pi and is called photophosphorylation. The transferase was found to catalyze formation of a -1,3 glycosidic bond. Briefly describe the differences between oligosaccharides and polysaccharides in terms of their biological or physiological function in higher organisms such as humans and mammals. Their fluidity is influenced by the amount of polyunsaturated vs saturated fatty acids in the phospholipids, and the amount of cholesterol.
Temperature can also affect fluidity.
You may indicate fatty acid intermediates by chain length, number of double bonds and sites of unsaturation as indicated for linoleic and arachidonic acids. Indicate what acyl-carrier is needed in these reactions and the cosubstrate used for the elongation reaction. It is not necessary to show other cofactors for these reactions. Palmitic acid 12. Briefly indicate 3 mechanisms for the regulation of this enzyme, indicating what metabolite or second messenger triggers this regulatory mechanism and whether each will increase or decrease its activity.
