Photosynthesis
Standard BIO1.LS1.8
Create a model of photosynthesis demonstrating the net flow of matter and energy into a cell. Use the model to explain energy transfer from light energy into stored chemical energy in the product
Explanation
Students should address the processes used during photosynthesis to convert light energy (solar radiation) into stored chemical energy. Additionally, consider the role of photosynthesis in capturing carbon, hydrogen, and oxygen needed to produce other cellular macromolecules such as proteins and DNA necessary for growth and reproduction. The chemical reactions needed for constant reorganization of these elements to form new compounds provides a way to transfer energy between systems across all levels of organization.

Cellular Respiration
Standard BIO1.LS1.9
Create a model of aerobic respiration demonstrating flow of matter and energy out of a cell. Use the model to explain energy transfer mechanisms. Compare aerobic respiration to alternative processes of glucose metabolism
Explanation
In addition to models that explore the major reactions of cellular respiration, students should be led to consider the way that the chemical reactions of respiration provide a way for energy and matter captured using photosynthesis to be transferred and reorganized by consumers. Cellular respiration is a set of reactions that allow for sugars to be re-organized to form other macromolecules. Students should consider differences in the efficiencies of different processes of glucose metabolism. Some of the energy released by respiration is used to maintain a constant body temperature despite constant loss of thermal energy to the surroundings. Both matter and energy are conserved throughout transformations.
