Includes most RasMol commands and has a command line, but has buttons and menus for many useful commands. Includes a comparator funciton that allows comparisons between two structures, molecules in the structure can be selected in a sequence window and there is a non-covalent bond finder function. http://www.merlot.org/merlot/viewMaterial.htm?id=83555 This tutorial/simulation consists of three topics. In topic 1, students look at the components of chemiosmosis in the bacteriumParacoccus denitrificans in which they step through animations of electron transport, proton gradient, and ATP synthase, learning the components involved in each.In topic 2, students construct chemiosmosis pathways in mitochondria and chloroplasts. Students will: 1) select the correct components (electron donor and acceptor, ETC, ATP synthase) and place them in the appropriate subcellular location ; 2) apply concepts about redox reactions, concentration gradients, and energetics to explain how chemiosmosis fits in a cell’s overall metabolism; and 3)summarize properties of chemiosmosis in organelles and Parcoccus denitificans. In topic 3, students follow the evolution of chemiosmosis and the role it played in the evolution of cellular life. Students will: 1) learn about chemical and cellular changes on early earth; 2) analyze efficiency of early forms of chemiosmosis; 3) compare mechanisms of non- and oxygenic photosynthesis; and 4) evaluate metabolic advantages of several endosymbiotic relationships. http://www.merlot.org/merlot/viewMaterial.htm?id=83557 Students construct chemiosmosis pathways in mitochondria and chloroplasts. Students will: 1) select the correct components (electron donor and acceptor, ETC, ATP synthase) and place them in the appropriate subcellular location; 2) apply concepts about redox reactions, concentration gradients, and energetics to explain how chemiosmosis fits in a cells overall metabolism; and 3) summarize properties of chemiosmosis in organelles and Parcoccus denitificans. http://www.merlot.org/merlot/viewMaterial.htm?id=83559 This simulation/tutorial consists of five topics. In topic 1, students make decisions for a paramecium living in a Petri dish that will determine if it will have enough energy to survive and reproduce. Students will 1) decide whether the paramecium will eat, swim, or reproduce based on its available energy and the amount of energy required for each activity; and 2) Learn about cellular processes that require energy. In topic 2, 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. In topic 3, students solve a mystery: where does ATP’s energy go in the glutamine synthetase reaction? Students will: 1) “interview” molecules to learn how ATP’s energy was released and absorbed in the ATP-coupled reaction; 2) reconstruct events leading to and from a high energy reaction intermediate; 3) identify which molecules (reactants, products, enzyme) got some of ATP’s energy. In topic 4, students learn what enzymes can and cannot do in a reaction by “hiring” an enzyme for the “job” of catalyst from a set of candidates that may be exaggerating their “qualifications.” Students will: 1) evaluate the claims of each enzyme to determine if they violate the chemical and thermodynamic properties of enzymes; and 2) select the “candidate” who is honest about what a catalyst can do in a reaction. In topic 5, students compare the energetics of photosynthesis, cellular respiration, and cellular work. Students will: 1) complete a review table that summarizes the energy inputs, outputs, free energy change, etc. of these processes; 2) review free energy change, ∆G, enzyme involvement, energy input and output. http://www.merlot.org/merlot/viewMaterial.htm?id=91309 VRML utility for the calculation and visualization of IR and Raman Spectra and 3D visualization of corresponding normal modes. http://www.merlot.org/merlot/viewMaterial.htm?id=83563 Students learn what enzymes can and cannot do in a reaction by hiring an enzyme for the job of catalyst from a set of candidates that may be exaggerating their qualifications.

Students will: 1) interview molecules to learn how ATPs energy was released and absorbed in the ATP-coupled reaction; 2) reconstruct events leading to and from a high energy reaction intermediate; and 3) identify which molecules (reactants, products, enzyme) got some of ATPs energy. http://www.merlot.org/merlot/viewMaterial.htm?id=259088 This web page was designed to teach students the  light-dependent reactions and light independent reactions of photosynthesis , it also includes a HTML Map with the different parts of a plant with an explanation of them. A couple of Java Applets  work as a laboratory to show the different gases that a plant expels during the reactions.  http://www.merlot.org/merlot/viewMaterial.htm?id=358537 Ever wonder why drugs get you "high?" This interactive website has an entertaining way of illustrating the effects that many illicit drugs have on the human brain..err mouse brain.
