Homework Statement

Formulate your own definition of what is meant by living organisms.

*I also posted the lab which this question is asked on in a thread called "Enzyme Lab."

The Attempt at a Solution

I don't think that this answer is right but don't know what else to write:
9. Living organisms include macromolecules which include proteins. Proteins in a tertiary or quaternary structure may form an enzyme (example: catalase) which are essential for the well being of the organism. A lack of an enzyme such as catalase prevents the organism from performing a certain function such as breaking down certain foods or poisonous materials such as hydrogen peroxide. An organism will not be able to live if it does not contain the required enzymes to carry out its functions.

Just a few thoughts...

Macromolecules include carbs, lipids, nucleic acids, and proteins. If you choose to focus on proteins, and specifically enzymes, you should also include why enzymes are so useful. Enzymes are catalysts...the reaction can take place without an enzyme but it may take a lot of time (in some cases, millions of years) to do so. You can also include a discussion of activation energy and how that's related to enzymes.

A living organism can be defined as a self-sustaining entity that is capable of performing essential biological processes such as metabolism, growth, reproduction, and response to stimuli. These processes are facilitated by the presence of enzymes, which are specialized proteins that catalyze biochemical reactions necessary for sustaining life. Therefore, living organisms can be characterized by their ability to maintain a stable internal environment, adapt to changes in their surroundings, and perpetuate their species through reproduction.
