How Do We Get Energy? (Chemical Reactions): Crash Course Biology #26
HTML-код
- Опубликовано: 22 май 2024
- Cells need energy to power the chemical reactions that keep their microscopic cities running, and most of that energy comes from a chemical called ATP. In this episode of Crash Course Biology, we’ll learn how our cells use energy, what an enzyme’s role is in chemical reactions, and what makes a reaction exergonic or endergonic.
Chapters:
Cellular Cities 00:00
What Is Energy? 1:18
The Laws of Thermodynamics 2:22
ATP 4:07
Chemical Reactions 6:42
Enzymes 9:13
Metabolic Pathways 11:04
Review & Credits 12:09

The best way to spend my 15 min break 😊
As a med student, watching this brings me nostalgia from AP Bio. Unfortunately, memorizing the Krebs Cycle never seems to leave us
Just listen to the Krebs Cycle song, helped me tonnes and is so catchy :)
We just started covering enzymes in my class. This is fantastic!
This was very well presented and the concepts were clearly and accurately represented. Well done team!
I have hope to understand biology. I could almost cry tears of joy. THANK YOU
I love this channel
Hey Crashcourse,
i have a question about the old biology- and the new biology series. How do they differ, is this more up to date and more acessible to a younger audience? Should i watch the other?
You really helped me to understand and be introduced to core biology concepts! Thankyou very much.
This is very entertaining to watch :D.
Great listen
Mitochondria is the powerhouse of the cell
Thank you!
Hi this video was so amazing
I love you, Hank Green and team. You’re so neat.
Dr. Sammy 🎉❤😊
It's very interesting
Thanks!
Informative
That camp fire toy is cute
Do you guys do vids on physics??
Cells are cool
☀ *energy noises*
i like this viodio
Energy is Mass times the speed of light times the speed of light.
Quantum physics
If energy can't be created or destroyed, where did the first energy come from?
🥰
Kon kon india se hai 🎉
First like that nerdy guy
Wait I can comment 😊
Why do I always click
😊
first one here
JOHN GREEN BOT.
I need help with life.
First! ;)
First!
I am indian
it might be my existential dread speaking but this has been my biggest fear... the more we uncover about life, the more of a sick joke is seems to be... this life that is built upon such simple rules where motion is energy and energy is life... the complexer a living form is, the more intricate it's inner workings is as it tries to have the right level of mobile and unmoving parts to gain an advantage on survivability... a continual repetition of renewal, nurish, grow, age and perish (all set on the principles of trial and error)... there would be no place for conscience and cognitive thinking had it not served well in the survival of life that hold such traits... I think therefore I am, but I only think because I'm meant to -...- good grief
I hate school who agrees

Destruction causes a release of energy,in its most simplistic for that is heat.
