I apologize for the lack of blog-posts this month… it’s been pretty busy around here.
Today’s post is about metabolic pathways, which the first-year students are deep into studying this month. Here is a link to a pretty illustration which was found on Wikipedia:
Each year in PBL, I struggle to re-remember facts about biochemistry, cellular signaling and metabolism including steps in the Krebs cycle*. (Why? Because I never took biochemistry.) Two years ago, I found the illustration below so useful that I decided to post it on the blog for the second time!
Next, a small joke: WWSD (or, what would Setlow do)? He could sing along to this Krebs Cycle song, found on ScienceGroove.com.
Publisher McGraw-Hill has placed some content from their textbook Anatomy & Physiology (7th edition) online for free, including this tutorial and quiz titled “How the Krebs Cycle Works“. After you take the quiz, relax by working a few of their Crossword Puzzles:
Salman Khan founded a non-profit group, The Khan Academy, with the goal of providing high quality free online educational materials to anyone in the world. This year, their collection of videos about Science, Math, Humanities, History, Finance and other academic subjects has grown to 1,800. A 10-minute video describing the educational content is here: Khan Academy.
Found on their Science – Biology category: a 13-minute lecture describing the ATP (adenosine-triphosphate) process.
On YouTube, author Faxe14011991 has posted this series of short animations/tutorials on cellular mechanisms, each of which is less than two minutes in length:
Finally, a video found on YouTube called Cellular Respiration (hey there Delilah)

* Dr. Krebs was a Nobel Prize laureate. Read the following text, found on the nobelprize.org page: ” The Nobel Prize in Physiology or Medicine 1953 was divided equally between Hans Adolf Krebs for his discovery of the citric acid cycle, and Fritz Albert Lipmann for his discovery of co-enzyme A and its importance for intermediary metabolism. “
