I just wanted to let you know how much your podcasts have helped me. I am a 33 year old stay at home wife and mother of 3, who has been out of school for a while ;). It was intimidating to go back to school, but you have made it a very positive experience, because I can relate to the way you teach! You make sense of every topic we are covering in Biology 12...so I thank you :).
My prof is completely incoherent. He talks for 3 hours straight then shows us these videos which explain everything better than he has in about 10 minutes. It's a waste of time.
God bless you! My terrible horrible AP biology teacher makes me want to cry every day and biology is my favorite subject! All of your videos have helped me so much, I can't thank you enough. I'm so glad there are generous and dedicated people like you out there who take their time to share these things.
I would like to say that I love watching your pod casts. You have helped me understand the my learning material in my college courses: Biology, Genetic, and Microbiology. I greatly appreciate having someone that can re-explain what my teachers are trying to teach us.
excellent video. however the "lock and key" model at 4:11 has since been changed to the "induced fit model" because the enzyme is not exactly the right shape to fit in and so needs to be "induced"
Nah it hasn't change, those are just theories as some Biologist said that the enzyme and substrate both have complementary shape so forming a perfect fit(Lock and Key hypothesis) BUT other biologist said that the enzyme change its active site shape and then the substrate fit on it(Induced fit hypothesis)!!! these are just assumption about how they work and they haven't been really prove about exactly how they work so learn both of them!!! Enzyme is very easy!!!!
The cofactor is a non-protein that bonds with the protein to complete the active site or 'activate' the enzyme. Now cofactors can be divided into two groups, which are prosthetic groups and coenzymes. A prosthetic group is a chemical that strongly bonds with the protein in which it becomes permanently bonded with the protein (such as heam). While on the other hand co-enzymes (usually oranic, non-protein) are weakly bonded to the protein which means they tend to break off once the reaction occurs
Man your videos are the greatest biology lessons on the web ! I've got a biology teacher which isn't as good ... if you see what I mean .. Your videos are a great and pleasant way to understand biology easily and with amusement !
Great video on enzymes. I wish I had found your series at the beginning of the semester! You make it so easy to understand without completely "dumbing it down". Thanks!
@@fancy4458 and spelling too (*your). Damn I was in school when I first commented. I'm now in my last year of engineering. Never would have thought this would happen. F*cking study enzymes kids! Specially if u have this sort of teaching for free!
All of your videos are so helpful. Thank you for taking the time to put them together. They have helped me in almost of my clinical chemistry chapters.
My Biological Sciences one teacher in college has put a link to pretty much all of your biology videos so these videos are also very good for teaching college students :).
Your videos are helping me so much to study for the TEAS exam. I wish I would have found your videos when I was taking the actual classes!!!!! Thank you so much!
Your videos have helped me so much. You have taught me more in an hour than most teachers have taught me in my lifetime. After seeing your videos I understand and I now like Biology. :) So thanks, from me and my study group!
Phenomenal video. Where were you 20 years ago in my first chemistry class?? I this should be part of every chem classroom in the states. More kids would be inspire to learn chemistry "The Central Science". Thank you
Thank u so much for your vids. They really are more simplified and easier to understand than my bio teacher and homework combined. You're a lifesaver :)
Such an interesting video. Thank you so much for it. :) It helps me a lot, especially in overcoming the boredom of studying using the books. Appreciate.
I have a Biology final next week, and I've been watching these videos to study. Somehow my college professor makes things far more confusing than Mr. Anderson. Thanks you so much!
I think the whole education system needs to change. now a days technology enables people to self-educate themselves much more efficiently. Testing and giving a specific curriculum is now obsolete and holds most people back from their full capabilities. P.S. I say this because i have learned so much more outside of school then i did during school. I use to hate science but now ive found a deep passion for it just by teaching myself online.
Hi Mr Anderson, I am an osteopathy student and for me it's very difficult to get this stuff in English language but I really found your videos very easy to understand and helpful to get all the pathology and chemists process, thank you very much for it and I hope that you continue making more videos about it congratulations.
Thank you for your videos! They are so helpful as they are helping me through my forensic chemistry degree! 4 exams that I was worried about until I saw your videos! Thanks again
Enzymes are proteins, proteins are made of amino acids. The function of an enzyme is to speed up chemical reactions within the body. Enzymes have important functions such as breaking down food, removing wastes from cells, fighting infections, as well as other functions. You can think about enzymes as a driver in a car. The car has fuel and could move, but it needs something to step on the gas pedal, once the driver(enzyme) steps on the pedal, the car (chemical reaction) moves forward.
10th grade in biology and chemistry dedicated class, studying the cell composition right now. This dude just removes the purpose of the book, perfect explanation.
