Tips for Biology 101 Signature Assignment: Home

Where should I start?

Finding information on enzymes and enzyme processes can be a bit intimidating. Don't worry! Hopefully the following tips will help you out:

A few terms you will want to use when searching for research related to your lab report:

1. Catalase/Catalysis
2. Peroxidase
3. Oxidative stress

The above are processes that occur in enzyme reactions. These are the terms you will want to use to find articles. You can search these terms as subjects in the library's databases, often by going to the Advanced Search. Searching by subject will get you more specific results. You can then add a term, such as something relating to cell protection. For example, try searching for articles on ways catalase protects cells as per the example below:

Additional tips:

• Remember to limit your searches by Full-text and Peer-reviewed (see example above)
• You can search for different spellings of a word by using * (see above: protect* will search for "protecting," "protects," and other forms)
• The research you find doesn’t have to be same experiment—you're looking for similar experiments done by others, what did they learn, did your results agree/disagree?
• For better results, see if you can limit your search with specific keywords (plants, animals, fungi, types of each)

What's a peer-reviewed article?

Peer-reviewed articles are very specific sorts of publications, usually found in databases that provide access to journals that publish these articles.

Common features of a peer-reviewed article include:

1. Multiple authors
2. Author affilitations and contact information
3. Discrete sections like an abstract, methods, discussion
4. Lots of data
5. Citations in the text and at the end of an article

Understanding peer-reviewed articles

Peer-reviewed articles can be tricky to read. The good news is that you can get a lot of information from the  article without having to read it beginning to end. When reading a peer-reviewed article, try the following:

1. Read the Abstract
   • This is an executive summary of the article. It briefly tells you what the experiment was about and what the researchers learned.
2. Read the Introduction
   • This goes a little more in-depth and explains why the scientists were conducting this experiment, their hypotheses, and what they expected to find out.
3. Skip to the end of the article and read the discussion/conclusion
   • It may seem strange to skip all the stuff in the middle of the paper, but much of it is a methods section in which the researchers discuss in detail how they did the experiment. This is less important than what they found out, which is usually in the last section or two of the article.
