Video Review on Glycolysis
These are videos on glycolysis and the author or rather creator happens to be my lecturer for biochemistry at my university and I am not being biased when I say he did a great job. I can certainly attest to the fact that I struggled my royal off trying to understand and cram glycolysis in A-levels or form 6 kind of like pre university if you are not familiar.
It was tough so tough that when I had to do this topic it seemed completely new to me
However because of my lectures methods I found myself understanding rather than cramming ….And the best advice I can give you if you are having problems is to clear your mind nothing is too difficult and just do it …. Not for passing the course sake but try to fully understand what you are learning and doing … this method had worked wonders for me I can type this entire blog video review just based on my memory of the video and what I learnt and understood so YaY ME !!!
Well firstly we have to appreciate that for each step of glycolysis there is an associated enzyme that helps catalyses the steps and since have done enzymes just by looking at the names and the reaction we can get an idea of what the enzymes in glycolysis are doing. Glycolysis can be viewed as well studying you have to give to get , meaning you have to give your time, effort and other things to get a good grade , a good job and well to pass a course. Now the purpose of glycolysis is to gain energy in the form of ATP and NADH and we will see how these are made and I don’t even need to go into detail you can look at this picture and get the jest of the entire pathway.
The video explains each step very closely so I have no idea what to say because the video speaks for itself. It explains each step in detail, it explains why ATP can be produced at only 2 steps in the pathway and it also explains how much ATP is made how much is the net gain and also how NAD+ is regenerated. So please have a look.
The second video deal with the faith of pyruvate after it’s made it.
Under aerobic the pyruvate is converted to acetyl coA which enters the TCA cycle via the enzyme PDH in the link reaction.
Under anaerobic it is converted to lactate as in fermentation in muscles, in red blood cells and ethanol be produced as in the process with yeast. And fermentation is a process which gains energy without the use of oxygen. And yes red blood cells do carry oxygen but the thing is they can’t use it since they have no mitochondria which is the site of aerobic oxidative phosphorelation or where ATP is produced (this is products of TCA are used).It shows how red blood cell regenerates NAD+ via converting pyruvate into lactate.
The video also explains how lactic acid is formed in muscles after vigorous exercises this reaction is catalysed by LDH.
Finally the video gives an insight into how yeast makes ethanol from pyruvate by the following pathway:
