Energy Use in Plants Flashcards
What can glucose by converted into?
Starch, cellulose, lipids and proteins
Why does the plant convert glucose into starch?
Starch is an insoluble carbohydrate so can be stored in cells. Because it is insoluble it does not affect the concentration inside the cells where it is stored.
What happens when glucose converts into starch?
Individual sugar molecules (glucose) become huge, long chains of identical sugar molecules (starch)
What is cellulose needed for?
Cellulose is needed by the plant for cell walls,
What happens when glucose converts to cellulose?
Individual sugar molecules (glucose) become long chains of sugar molecules held together by weak bonds (cellulose). It is very similar to starch but the long chains are cross-linked to form a meshwork.
What is protein needed for?
The plant needs protein for growth and repair and also to make enzymes.m
How is protein made?
Glucose (individual sugar molecules) and nitrates become lots of amino acids which then become proteins (huge, long chains of different amino acids)
Why is glucose converted into lipids (fats and oils)?
To store in seeds
How is glucose converted into lipids?
Glucose (individual sugar molecules) convert to a lipid structure.
How is glucose stored?
As insoluble starch.
