Connecting Concepts: Cell Biology/Thermodynamics 2: Energy conversions

Students follow energy conversions in Euglena, during photosynthesis, respiration, and cellular work. Students will: 1) review definitions and properties of endergonic and exergonic processes; 2) explain, in qualitative terms, free energy changes in the universe, photosynthesis, respiration and cell work; and 3) identify the type of work (chemical, mechanical, etc.) being done in a number of cellular processes....

Part two of five interactive exercises that investigate the role of thermodynamics in cell activity. Uses Euglena to illustrate the concepts. This is a vital and not easily understood concept.  Very well written and well organized. Requires students to draw conclusions from information presented.
