LABORATORY 1 - Enzyme Catalysis
Thursday, October 5, 2017
TMEC 332 All students & Tutors - Tutors will join students in the lab.
Labs: 343 & 344

Hey Group 3!

I'm so excited to get to work with you all this year. From just one day, I can already tell you all are a talented and curious bunch. I can't wait to see what we get up to in the lab. Hopefully, we can all learn as much biology as we do about which TV shows we should watch next!

Check out the link on the right for info about Lab 1, which is on enzymes and how they catalyze (aka speed up) molecular reactions.


Enzymes are proteins that increase a specific type of reaction, turning substrate(s) into product(s). In this comic, the enzyme turns the dark green molecule into a light green molecule. As scientists, we can change the DNA sequence of an enzyme (which will change the protein sequence) to prevent the enzyme from doing its job (make it catalytically inactive). This is why the second enzyme in the comic is missing arms - it's "truncated," aka has a shorter protein sequence, and can't turn the molecule from dark green to light green! When scientists change the DNA sequence, it is called "mutating" and it can be a very helpful genetic technique if we know the identity of the enzyme but not what it does (its function - what reaction does it catalyze?). Ask me more at our next lab! (Credit to Cellular Scribbles by Vicky Chou and check out their other comics on Facebook!)

LABORATORY 2 - Photosynthesis
Thursday, October 26, 2017
TMEC Tutoring room: 116
Labs: 343 & 344

What's up, Group 3?!

This week we'll be learning about photosynthesis and how rates of respiration in plants can be altered by factors like leaf color, distance to light, and temperature. We're also going to talk about how the two images below are related. Seriously, is that a mouse with a blue light on its head?? What does that have to do with plants and photosynthesis?? You'll find out this Thursday!

Be sure to review the procedure before we meet!

Scientists can add a molecule that senses light into the brain of a mouse. Like a plant pigment, the molecule in the neurons of these mice can capture light energy, specifically from blue light. The light energy causes the molecule to change shape and leads to the activation of neurons. Using this tool, scientists can understand the function of specific sets of neurons or areas of the brain when they activate them with blue light. For example, some neurons cause the mouse to move, while others can cause the mouse to overeat. Ask me more about it in session Thursday!

LABORATORY 3 - Cellular Respiration
Thursday, November 30, 2017
TMEC Tutoring room: 116
TMEC Learning Studio 106 for Lab

LABORATORY 4 - Transpiration

Thursday, January 4, 2018
TMEC Tutoring room: TBA


Ever wondered how the tallest tree in the world gets water from its roots all the way to the tallest leaf? No, they're not pulling an Elphaba from the musical Wicked and "defying gravity." They actually take advantage of the characteristics of water molecules and a process called transpiration. We'll learn all about it during Lab #4!

Please bring an electronic device that connects to the internet so we can have a more interactive session :)
