This document contains a complex exercise on metabolism. It can also be used as an exam or in preparation for an exam.

It requires knowledge about enzymes and how they work, the general categories of metabolic reactions as well as general knowledge about photosynthesis and cellular respiration.

The exercise is tailored to require about 60 min of work when done in "one sitting" and in writing.

It includes the solutions and references to the following competencies:

-        I can describe diagrams formally.

-        I can describe the data depicted in a diagram.

-        I can analyze and interpret the data depicted in a diagram.

-        The students know the basic categories of metabolic processes and can distinguish them from one another. The students know the biological significance of these processes, and they can name examples for where these processes occur.

-        I can name and compare examples for anabolic and catabolic processes, and I can define scientific terms related to these processes.

-        I can describe the course of enzyme-catalyzed reactions, and I can explain the influence enzymes have on substrates involved in these reactions.

-        I can explain the significance of the active site of enzymes for their substrate specificity and their reaction specificity.

-        I can list factors that influence an enzyme’s activity, and I can explain how these factors influence an enzyme and its activity.

-        I can describe how water, carbon dioxide, and oxygen are part of a simplified cycle of photosynthesis and cellular respiration.

-        Using specific examples, I can describe and explain the functions of products of anabolic and catabolic metabolic processes of an organisms in the organism itself and their significance for other organisms.
