Today we finished talking about energy in living systems. We went over some reaction types that are relevant in biology. It's important that you read the textbook for this section of the unit. There are also some textbook questions to answer in preparation for next week's test. We then began a "jig-saw" activity on Enzymes. This will continue tomorrow when the "experts" present what they've learned to their home groups. For homework, please also read the lab on pages 82-83 and page 762 in your texts. Here is a link to a page showing links to on-line animations/tutorials on enzmes...they can be very helpful when learning something new and abstract like this. Enzyme animations and tutorials
