Photosynthesis and Respiration

013 - Free Energy Capture and Storage
Paul Andersen details the processes of photosynthesis and respiration in this video on free energy capture and storage. Autotrophs use the light reactions and the Calvin cycle to convert energy from the Sun into sugars. Autotrophs and heterotrophs use cellular respiration to convert this sugar into ATP. Both chemosynthesis and fermentation are discussed. The evolution of photosynthesis is also discussed.

i hope he realizes that his video from a DECADE ago is still being used by students to pass their classes THANK YOU SO MUCH

[@shard9589]

My teacher doesn't teach at all and actually tells us to watch these videos

[@marieeem]

He is my teacher for every science.

[@user-wm8lv8kq1m]

wait is this the guy who went over science and pseudoscience? I just watched it, Now i can put a face to the voice.

[@spamdrea]

I'm taking my AP bio exam tomorrow. I understand more from your videos than my teacher ever did in class. Thank you Mr. Andersen!

I guess this is what all Biology teachers do...

[@juno7266]

I understood more within the 15 minutes that I watched this video than 2 weeks worth of 1 hour botany lectures! Thank you so much!

[@michellecarlamaier1923]

HUGE FAN FROM AUSTRALIA! I've watched your videos all through my bachelor and honors degree and now at a doctorate level i am still referring back to them for revision. Thank you, Mr Anderson! :)

[@goldenboys6367]

haha burn

[@captotake14]

i love how you always wish us well by saying i hope that's helpful.. you're the only reason i'm passing biology thank you so much!!

[@sounndproof]

You are such a great teacher! My school is self directed so I rarely get to hear someone so intelligent speak and explain the material. I really appreciate it.

[@estefaniacristobal8489]

AGGGHHHH I FINALLY UNDERSTAND! This was extremely helpful.(: All those hours of reading and studying my AP Bio book didn't teach me as much as this 15 minute video did. Thank you!

[@sheema30]

Yes.. that was extremely helpful.. I think it's the way you throw your voice and emphasize key words, that is what helps me. I enjoy all your videos. I am a nursing major and hope to get into nursing school next September. I hope you will have more videos that will help me along the way as I progress. Thanks again

[@grace99playz]

nah thats what i was thinking too

[@Bzooga]

THANK YOU! My biology teacher is horrible at explaining everything, and barley allows time for us to copy down notes. We almost never get to copy diagrams. I listen to these videos before tests when I go to bed, and they help a lot. Thank you.

[@iamtheman584]

i swear i learn more in a 15 min video on youtube than what my professor lectures in a week.

[@katherinescarborough6539]

this video just saved my entire biology grade, thank you paul.

[@jessicamurawski]

This video is literally saving my life in my college cells and molecules class. I had no idea what was going on or how any of these processes worked together.

[@ethanhubbard2019]

I love how at 12:51 hes talking about the matrix in cellar respiration and hes called mr. Anderson.... its just funny to me. amazing video btw! you really make it easy to understand

[@youngnattymusic]

please be my biology teacher >_

[@TacoSt8]

detail spot on 8:40 idk how someone thinks its a good idea to name everything that have no importance at all in the process, glad you realized it!

[@dav9612]

"which I don't ever want you to memorize" DEAD

[@brennanlewis6508]

rip😪

[@orbsandtea]

Videos such as these should be assigned for homework. I think it's got something to do with pride that they're not assigned as such by many teachers yet.

[@MetallicGray97]

I wish I had this guy as a teacher. He is what every teacher should strive to be like.

[@SailaMaham]

That was incredibly helpful! We study the processes in so much detail in class that I can't understand the basic thing. We're expected to memorize the names of all the different kinds of molecules (including the proteins) involved in the steps of photosynthesis and respiration, so that sucks out all our interest. This gave me a clearer picture! Thank you! :)

[@capri325]

You taught better in 15 minutes than my teacher did in a week and a half. Thank you so much for this video!

[@sarahparochniak3349]

Thank you so much for all of your videos. You are an extremely talented teacher and have helped me grasp just about every concept in biology

My understanding of subject of photosynthesis and respiration at the atomic level is superficial. At age 75, to expect more would in vain. But it is great to have the knowledge of the elements that give planet earth life. I worship the sun, the earth and the ever expanding universe.

9:40 Convention suggests the energy from the light is stored in ATP and NADPH but the bulk of the light energy is used to break the strong H-O-H and O=C=O bonds and replace them with the weak O=O bonds. It is the rejected oxygen that actually 'stores' most of the energy from the light.

[@keithross7058]

11:42 remember that it is the oxygen, not the glucose that 'stores' the energy. Glucose is a strongly bonded stable molecule - it is oxygen that is the unstable reactive one. But you won't find this in text books, YET. But there is a group of us who are trying to make the role of oxygen clearer. After all it is the oxygen, rejoining the carbon in fossil fuels that has filled our atmosphere with carbon dioxide and causing climate change.
