What are the characteristics of living things?
Evolves, grows, reproduces, responds to their environment, is made of cells, based on a universal genetic code, maintains homeostasis, & has a metabolism

What is the energy needed to start a chemical reaction called?
activation energy
300
Why is a rock not alive?
no DNA, does not respond to its environment, no cells, no metabolism, no homeostasis

After it reacts with a substrate, can an enzyme be used again?
YES
500
Why can't you scientifically study ghosts?
Science deals with the normal, natural world. It does not deal with the paranormal.

Why do we talk about locks and keys (or wrenches and nuts) when we talk about enzymes?
Each enzyme only works with one specific kind of substrate.
