Enzymes are biologic polymers that catalyze the chemical reactions that make life as we know it possible. The presence and maintenance of a complete and balanced set of enzymes is essential for the breakdown of nutrients to supply energy and chemical building blocks; the assembly of those building blocks into proteins‚ DNA‚ membranes‚ cells‚ and tissues; and the harnessing of energy to power cell motility‚ neural function‚ and muscle contraction. With the exception of catalytic RNA molecules‚ or

The Rube Goldberg Machine that my group and I made is called the “Yummi Nummies”. This invention of ours is significant because it helps solves the problem of having to feed pets. It can be used for many different animals in need of being fed. For example‚ Yummi Nummies can be very productive in zoos. This machine can shrink the chance of a zookeeper from getting hurt if he were to bring in the food to a wild animal’s cage. This machine is not simply only used for zoos‚ this machine can also help
