Occurs in the mitochondria - releases energy which allows them to convert the rest of the glucose into other useful substances which can be used to build new cells
Seeds
Glucose is converted into lipids for storing seeds which also store starch
Protein synthesis
Glucose combined with nitrates to make amino acids which are made into proteins
Enzymes are proteins and many other strucural parts of plants
Nuts and seeds also contain large amounts of protein as they need to sustain the plant
Storage
Soluble glucose is converted into starch to not affect osmosis
