There are four sketches below. the first sketch shows a sample of substance x. the three sketches underneath it show three different changes to the sample. you must decide whether each of these changes is possible. if a change is possible, you must also decide whether it is a physical change or a chemical change. each sketch is drawn as if the sample were under a microscope so powerful that individual atoms could be seen. also, you should assume that you can see the entire sample, and that the sample is in a sealed box, so that no matter can enter or leave.

Description: biological systems 5 differ from chemical systems when it comes to equilibrium. in a chemical system once equilibrium is met, no other reactions occur. in a biological system, a dynamic equilibrium is used when a substrate is turned into a product, another reaction creates the same substrate thus keeping the concentrations stagnant. this allows for cells to continually make new compounds without messing the delta g for the systems instructions: write a response to the following prompt and then respond to your peers. your individual response is due thursday at midnight (cst) your response to your peers is due saturday at midnight (cst) prompt: propose what would happen if a living cell all the sudden reached chemical equilibrium. also discuss the effects of build up of a particular substrate on a biological system. how would this affect overall delta g's?
