Multiple Choice

Which of the following statements best describes the main function of glucose in animal cells?

• It is a structural component of cell walls.

• It is the major energy source for most cells.

• It is used to store genetic information.

• It acts as a catalyst in metabolic reactions.

Draw

Draw on the image whether it is alpha or beta glucose and circle what makes you think this. If you can, write underneath either 'structural' or 'energy'

Open Ended

Explain the structural difference between alpha glucose and beta glucose and discuss how this difference affects their biological roles.
