My name is Kyle Kobe. I have been a biology teacher since graduating college in 1999. Since 2004, I have been a biology teacher at Beverly Hills High School. These biology videos are a collection of PowerPoint presentations that I use in my biology classes at Beverly Hills High School. The content in these videos are taught mainly to the 9th/10th grade level. So whether you are a student of mine, a student elsewhere, or simply curious about the life sciences, I hope you find these resources helpful.
"Non-chemical means of fertilising soil" is simplistic. He means improving soil structure using plants and animal waste locally, and reducing physical loss of soil into watercourses are the way to reduce risk of eutrophication events.
Tells little slowly that you telling you are very nice until softball you're telling a lot of very very voice so I cannot understand your language and your Herbalife what is a heterotrophs explain that one in one more video need like this I don't want your voice
A follow-up video on how and why unsaturated fatty acids oxidize easily would be great, especially as it relates to health. Best explanation of this notions ice seen yet. Thank you
I agree and love your video however I wish to point out that , for certain subjects that teach very macro topics ( policies etc) that can be very vague and there is no info on practice tests, very hard to prepare…. had to crush , but for scientific subjects I love to practice because I know how to
Glycolysis, the process of splitting a six-carbon glucose molecule into two three-carbon pyruvate molecules, is linked to the Krebs cycle. I searched things up and it says that in glycolysis, 4 atp molecules and 2 NADH are produced. But in this video, glycolysis only produces atp and pyruvate. 2 atp molecules are produced in glycolysis and 2 pyruvate. the other 2 atp molecules are produced in the krebs cycle, and the 2 NADH molecules are also produced in the krebs cycle, both of them came from the 2 pyruvate molecules from glycolysis. I think since they are linked, that's why some sources say 4 atp molecules and 2 NADH are produced in glycolysis. Go to 8:35, you can see 2 atp molecules at the top, which was produced during glycolysis, and the 2 other atp that was produced in the krebs cycle, and you can also see the 2 NADH molecules inside. That matches 4 atp molecules and 2 NADH, which was from different sources on Google! So in easier terms, glycolysis and krebs cycle is linked to each other so maybe that's why sources say that. In glycolysis, 2 ATP and 2 pyruvate are produced. In krebs cycle, the 2 pyruvates from glycolysis produces 2 more ATP molecules and 2 NADH molecules. All in all, 4 atp molecules and 2 NADH are produced. And that matches what Google and many sources say! Hope this helps and feel free to correct me!
this is from BYJU'S: "The final output or end product of Glycolysis is two molecules of pyruvate, ATP, NADH, and water. The end product of glycolysis in the aerobic condition is pyruvate and lactate in anaerobic conditions." only 2 molecules of ATP is produced in glycolysis, just like i said in my first reply. the other 2 is produced in the krebs cycle, coming from the 2 pyruvates from glycolysis. some sources may say that 4 atp is produced because they treated glycolysis and krebs cycle as one cycle, even though they are a SEPARATE CYCLE. (they are only linked) idk, i might be wrong though, feel free to correct me!
Update #3: I watched Crash Course Biology and it said that GLYCOLYSIS produces 4 atp, BUT the video was 12 years ago. And this video by beverly biology was 1 year ago and UPDATED. So it might be that things changed through further study. If you watch Crash Course Biology #7 which is about cellular respiration, Hank said that we're not even that sure about the total ATPs produced, whether its about 38+ or 30 something when you combine all the processes. but again, that video was 12 years ago. this video by beverly biology was an UPDATED overview of respiration and it's new, considering it's just 1 year ago.
Watched about 10 videos on this and could not understand the difference. this cuts everything down and keeps it simple and easy to understand! thank you!!
I love his videos but lack of oxygen is not necessarily from exercise. That’s gonna bring in oxygen. Which is why it’s called aerobic exercise for instance. It’s going to drive up the rate of reactions and help to burn up the carbs, ie, those glucose molecules. Sitting on your butt, eating high processed foods that are shelf stable and are made so by removing all the water content, which is where you get most of your oxygen for the Krebs cycle and electron transport chain. GMOs, those that have been modified to withstand Roundup ready and non GMOs sprayed with glyphosate to induce early harvest are also extremely dehydrating. Both to the environment and to our bodies. And considering most foods in the grocery store are GMO or somehow tainted with glyphosate, ESP if non organic, you know you’re not getting the oxygen you need to convert your carbs to ATP and so the body has to convert em to fat and shove em in fat cells via insulin. And then which leads to all kinds of other health issues.
Thank you so very much for explaining this in a way that's easy to understand. The pace and sound of your voice is better than any other of video i've found. Keep the video's coming!!!
Very good video explanation. I have a question: How is that possible for the macromolecule viral-DNA gets inside the host cell nucleus since DNA do not fit the nuclear pore to gets in or out? This is a doubt that's me occur. Thank you very much!
