Easy glycolysis mnemonic for beginning students. You may need to pause/watch it more than once - and there's a self-paced FLASHCARD TUTORIAL at: http://www.helphippo.com/flash/flashcards.html All cellular respiration tutorials can be found in our playlist: http://www.youtube.com/playlist?list=PLIPkjUW-piR0Bsauys9qL-UNZ2dPVPeGE This tutorial introduces simplified intermediates structures/ ATP/NADH steps - the next part of our tutorial has the full structures/enzyme names. Please SUBSCRIBE for new videos: more cool stuff coming as we get more Hippo Helpers! This explanation also explains the difference between the investment and pay-off stages of glycolysis, as well as the important regulatory step, the "committed" step of phosphofructokinase-1. http://www.helphippo.com - for more video tutorials organized by topic/year.

Hi all, I was wondering if you know of any other source of hydrogen ions and lactate production in a cell APART from glycolysis? Is it produced by normal cellular processes? According to my understanding, H+ and lactate are produced under hypoxic conditions. Glucose is broken down into lactic acid with then dissociates into lactate and H+. Thanks!  

The secretion of glucagon by pancreatic α-cells plays a critical role in the regulation of glycaemia. This hormone counteracts hypoglycaemia and opposes insulin actions by stimulating hepatic glucose synthesis and mobilization, thereby increasing blood glucose concentrations. During the last decade, knowledge of α-cell physiology has greatly improved, especially concerning molecular and cellular mechanisms. In this review, we have addressed recent findings on α-cell physiology and the regulation of ion channels, electrical activity, calcium signals and glucagon release. Our focus in this review has been the multiple control levels that modulate glucagon secretion from glucose and nutrients to paracrine and neural inputs. Additionally, we have described the glucagon actions on glycaemia and energy metabolism, and discussed their involvement in the pathophysiology of diabetes. Finally, some of the present approaches for diabetes therapy related to α-cell function are also discussed in this review. A better understanding of the α-cell physiology is necessary for an integral comprehension of the regulation of glucose homeostasis and the development of diabetes.
