Photosynthesis: The Original Solar Power: Crash Course Biology #28
HTML-код
- Опубликовано: 3 июн 2024
- Photosynthesis is a powerful process that is responsible for some of life’s most vital functions. In fact, consumers like us rely on photosynthetic producers to harness energy from the sun so that we can survive and thrive. In this episode of Crash Course Biology, we’ll explore photosynthesis in two acts, and learn how the process works inside and out.

Producers & Photosynthesis 1:26
Chloroplasts 4:04
The Light-Dependent Reactions 5:01
The Calvin Cycle 7:30
Carbon Fixation 10:27
Review & Credits 11:33

I think it's pretty important to mention that we do make enough food to feed the planet, but that a lot goes to waste. Might be outside the scope of this series.
I was gonna comment this; it's not biology, but many potential solutions to feeding a growing population have nothing to do with growing more food.
And into animal products, which is highly inefficient. But yes, it's not a series on sustainability, I think they just tried to find a relevant field of application.
a lot of it goes to waste intentionally to prevent people from getting free food, since giving away food would hurt profit margins
I agree
I’m one of those horticulturists looking to dive deeper into the science to help our future!! Thanks for posting!!
Just a reminder that since plants perform both photosynthesis AND cellular respiration, we need them way more than they need us.
Ribulose Biphosphate! I remember how this molecule was taking up space in my mind for at least a month both in Biochemistry and in genetics! I loved my biochemistry, genetics, and molecular biology and cell biology classes. Getting down to the literal molecule of how life works.
Always a wonderful start to my day when crash course uploads.
Perfect timing lol. I just had my bio lecture on photosynthesis today.
So in other words, we all run on fusion energy. Cool!
Well done :) I think the toughest part of biology is going to be keeping the diversity of plant life in / near its region / area . . .
This video and photosynthesis are awesome.
Thanks
Today I mainly learned that my cactus does not enjoy getting fist bumped
Interesting to see Bangalore K R market in the intro of the video
I'm here for class !
hello future students
Thanks!
i tried fist-bumping poison ivy, all did not go according to plan
A science show spreading the "Sugar makes kids hyper" MYTH. Cool...
Thanks Dr Sammy! Always rad! 😁😁
new edpuzzle just dropped‼️‼️‼️🔥🔥🔥
How do you cut open something as small as a chloroplast?
I have a carbon fixation
You said at 08:15 you said “these three carbon molecules”. Was this supposed to be “carbon atoms”? This may seem obvious to those who know, but to someone that doesn’t know, you said it creates a group of molecules with 3 carbon atoms each. Does this mean 3 Carbon atoms per MOLECULE in said group? But then why refer to it as “three carbon molecules”?

2.5 million ants to one human? Cant we just eat ants?/s
