Looking at the model, which is the best explanation for how chemical energy is transferred within cells?

• The bond that joins the adenine molecule and ribose sugar releases energy when broken

• The bond that joins the adenine molecule and a phosphate group releases energy when broken

• The bond that joins the second phosphate and third phosphate group releases energy when broken.

• The bond which joins the phosphate groups to the ribose sugar release energy when broken

A student is developing a model on photosynthesis. In order to complete the model, she needs to investigate how the different parts of the plant react during photosynthesis.

She compared the cells in the leaf of a corn plant and the cells in the stem of a corn plant. She discovered that the leaf cell contains more chloroplasts than a cell in the stem of a corn plant.

Based on this observation, what is the best comparison of the cell in the stem, to the cell in the leaf?

• The cell in the stem will synthesize more sugar than the cell in the leaf

• The cell in the stem will have a higher chromosome count than the cell in the leaf

• The cell in the stem will produces fewer proteins than the cell in the leaf

• The cell in the stem will use less carbon dioxide than the cell in the leaf
