Glycolysis Steps 1-5 Cellular Respiration Investment Phase
Leah4sci.com/glycolysis presents: Glycolysis Steps 1-5, the Investment Phase of Cellular Respiration

This video focuses on the first half of the glycolysis pathway, in which energy is invested to trap a molecule of glucose in the cell and eventually break it into two molecules of glyceraldehyde-3-phosphate. You’ll learn how the glucose is phosphorylated, isomerized, and ultimately lysed into two 3-carbon sugars on the way to becoming pyruvate in the second half of the pathway.

Leah, you don't know how happy am I to find your MCAT channel! I owe my As in organic chemistry to you! I'm taking biochem now and all of your amino acid videos and glycolysis videos are so helpful! I wish I could find one of your videos for every topic I'm learning. You make everything so easy to understand

Thank you this video helped out so much. Quick question - it looks like you drew glucose with the OH's in axial positions. Shouldn't they be pointed at an angle instead of straight up/down?

You're very welcome! In this video, glucose is depicted as a Haworth projection. This depiction is not meant to convey the ring conformation of the molecule. If we were to draw glucose as a chair conformation, it would show substituents in axial/equatorial positions, but in a Haworth projection, substituents are viewed as being above or below the ring structure.
please complete the metabolism you are the best

Aww, thanks for your kind words. The second half of the glycolysis pathway (payout phase) can be found here, along with with my glycolysis cheat sheet: leah4sci.com/glycolysis
You must of got a perfect score on your science section of the MCAT. Your explanation is fantastic! I appreciate all the details.

Is there a second video for the pay off phase?

Yes. Working on final edits and hope to publish it next week
You save me!! Thank you (I am more than appreciative for this, but can we look forward to a CAC video too?) The specific regulation (activators and inhibitors discussed in Khan Academy's vid) of CAC are a bit confusing
