You must answer all questions in complete sentences

Photosynthesis

(p.43)

What are the products of a photosynthesis reaction?

What does it mean that photosynthesis an endothermic reaction? Where does the required energy come from?

(p. 734)

Write the net balanced equation that describes photosynthesis. Circle the glucose molecule in the reaction.

 

Polymers

(pp.654 - 656)

Because polymers are very large molecules, they are difficult to represent. Describe how a polymer is represented and give and example other than glucose.

(c) Draw a complete glucose molecule.

Using an addition reaction, illustrate the formation of a polymer from monomer units.
