I hope your students know how blessed they are to have you as a lecturer. I am learning much more than my current class.

[@Campbellteaching]

Thanks Sheri, I hope your course and studies go well.

You are absolutely brilliant! You make it all sound so easy to understand. We all want you as our lecturer. Keep feeding us this academic food Dr. John Campbell. You are a legend! I am most grateful for your teachings. Thank you. Xxxxx

[@TheCreamy88]

Dr. Campbell provides a clear understanding of glucose metabolism, helping us all who desire to grasp this topic. His sense of humor makes learning fun! Thank You

[@Phillips1758]

I wish you were my teacher/lecturer. Suffering from Asperger’s, ADHD, and LD, to name a few, has made studying one of the most difficult challenges of my life. Such a great teacher, Sir, your ability to transfer knowledge is amazing.

Don't let these difficulties stand in your way

Amazing ! You are absolutely amazing. I am a student of biomathematics and I am working on diabetes mathematical modeling. I need to clear the whole system behind diabetes. And here I found your lectures. Thanks

[@hw9876]

Thank you, Dr. Campbell! You are a gifted teacher. You have a straight-forward and sensible way of explaining these concepts to make them understandable. I am grateful I found you today.

[@yairmiron329]

Hi Dr. John Campbell, thanks for another good lecture. One thing i dont really get, wherever i check i see that normal value for glucose in the blood is between 70-110 but you sad at the begining of this lecture it should be between 4-8. What have i missed? Thanks

[@Campbellteaching]

You are in mg per 100 mls of blood units, in Europe we measure it in millimoles. I agree, its a pity we are not on the same page for units.

[@yairmiron329]

Thanks for the quick replay. There are lots of videos on youtube with all the different subjects for med school but yours are by far the easiest to understand. I dont know if you realize how helpfull are your videos and how easy is to learn when you have a good lecturer. Ps: please shot a video also on blood PH, anion gap and the disorders/mixed disorders of the blood PH. Thank you again for these wonderfull lectures.

[@afghanhaqparast7148]

If we want to thinking logically we should study the lectures of Dr John Campbell😍

[@scottseptember1992]

Amazingly clear. What university are you lecturing at?

[@Campbellteaching]

Hello Scott, Im at the University of Cumbria in the UK. Where are you based? John

[@scottseptember1992]

Dr. John Campbell Thanks for your reply Dr. John Campbell. I'm currently attending pharmacy school at the University of Oklahoma Health Sciences Center (OUHSC) in the US. Despite having learned some of this material, you never cease to amaze me in the respect that I always learn something new or see things from a different angle whenever I watch your videos. Even before I was accepted into the program, you helped me study for the biology section of the pharmacy college admissions test/PCAT for which I got a 99% on, so I appreciate everything!

[@satan_with_needs7946]

I’m studying advanced clinical practice at university of Cumbria and could have done with finding this videos a long time ago . Very easy to understand . Thank you

[@mwasie]

One student said 'can't you tie glucose molecules into strings and pull them by the strings. lol creative idea.

[@ifeomammachukwu9727]

What is the function of the alpha cells of pancreatic islet

[@Campbellteaching]

production of glucagon, which raises blood sugar levels

[@CaptainSteve777]

The brain can get along quite well using ketones for energy. Some say it's the brain's preferred source because when both are available, the brain uses ketones FIRST..

[@rodaf2]

Sorry to report some mistakes in this nicely presented lecture. At 5:00, you mention all energy is provided by the mitochondria. Glycolysis produces ATP from glucose and takes place in the cytosol, not in the mitochondria. At 5:30, you mention that you need oxygen to create energy. Glycolysis does not require oxygen. Simplification is good, but to state all energy comes from the mitochondria is really just incorrect.

[@aljid2000]

He probably meant the mechanism of oxidative phosphorylation

[@ifeomammachukwu9727]

What causes diabetes mellitus

[@Campbellteaching]

Do you mean type 1 or type 2? The causes are different.

[@Hamidplzz]

now i see the butterfly effect caused the coronavirus. you're student sneeze and coughing. 😅

[@phoenix73662]

lame lecture I would hate being in this class. he is extremely vague
