Necessary conditions for starch synthesis include availability of glucose molecules, enzymes such as starch synthase and ADP-glucose pyrophosphorylase, presence of appropriate cofactors and ions like magnesium, and optimal pH and temperature for enzyme activity. Additionally, presence of amylopectin and amylose chains for starch structure and proper cellular organelles like plastids for starch storage are also required.
Yes light is neccesary for starch synthesis.This is do to the proccess of photosynthesis creating the sugar glucose the glucose is then converted into other forms of carbohydrates e.g sugars for respiration, starch for storgae, or cellulose for cell wall, Lipids e.g. lipoproteins and proteins e.g. enzymes. Therefore meaning that before starch can be produced the glucose must first be produced through the proccess of photosynthesis which requires both sunlight and chlorophyll.
The primary enzymes involved in the synthesis of starch are starch synthases, which catalyze the addition of glucose units from ADP-glucose to form amylose and amylopectin, the two main components of starch. Additionally, branching enzymes (such as branching enzyme 1) introduce α-1,6-glycosidic bonds, creating the branched structure of amylopectin. Other enzymes, like debranching enzymes, may also play a role in modifying and remodeling starch during its synthesis and metabolism.
Dehydration synthesis
Starch phosphorylase is primarily involved in starch catabolism, breaking down starch molecules into glucose units. It catalyzes the phosphorolytic cleavage of α-1,4 glycosidic bonds in starch. Starch anabolism, on the other hand, involves the synthesis of starch molecules from glucose monomers by enzymes like starch synthase and ADP-glucose pyrophosphorylase.
The monomers used in the synthesis of amylopectin are glucose units, while the monomers used in the synthesis of cellulose are also glucose units but arranged in a different way, forming beta-D-glucose units.

The storage product in plants resulting from dehydration synthesis of many glucose molecules is starch. Starch is a polysaccharide composed of multiple glucose units bonded together, and it serves as a long-term energy storage molecule in plants.

They are responsible for the synthesis and storage of starch granules, through the polymerization of glucose.
dehydration synthesis
Starch phosphorylase is primarily involved in starch degradation by catalyzing the conversion of starch to glucose. In vivo starch anabolism involves the synthesis of starch molecules from glucose, which is carried out by enzymes like starch synthase and starch branching enzyme. Therefore, starch phosphorylase is not directly involved in the biosynthesis of starch in living systems.

Starch is produced in the chloroplasts of plant cells, specifically in the stroma, which is the fluid inside the chloroplasts where various enzymes are located for starch synthesis. The process of starch production involves photosynthesis, where plants convert sunlight, water, and carbon dioxide into glucose, which is then polymerized into starch for storage.
The monomers used in the synthesis of amylopectin are glucose units, while the monomers used in the synthesis of cellulose are also glucose units but arranged in a different way, forming beta-D-glucose units.
