• A. The energy released from glucose is used to produce ATP during respiration
• B. Glucose is stored as glycogen in plants and as starch in humans
• C. It is an aldose sugar
• D. It is present in both D and L forms

Answer 1

The correct option is B

Glucose is stored as glycogen in plants and as starch in humans

Glucose is an aldose sugar, that is it has an aldehyde functional group and is found both in D- and L- form, based on the arrangement of the functional groups around the asymmetric carbon atoms. Glucose is stored in plants as a polymer called starch and in animals as glycogen.
