Carbon & Biological Molecules: What is Life Made Of?: Crash Course Biology #20

Despite the diverse appearance and characteristics of organisms on Earth, the chemicals that make up living things are remarkably similar, often identical. In this episode of Crash Course Biology, we’ll look at the building blocks of the four major classes of biomolecules, how those join up to form macromolecules, and how a team of six atoms forms the vast majority of living matter.

Grown adult in his 30s, and I enjoy watching these because they remind me of PBS science shows from back in the day.

I was today years old when I learned about CHNOPS, and how they integrate into everything.

[jcinaz]

I am so pleased that you are doing this course. You have an engaging presentation. Thanks.

I smashed my chemistry class thanks to crashcourse.

[hakimitus]

Dude gives off serious LeVar Burton vibes and I am HERE FOR IT.

[shadetreemetalworks]

As an old person, apparently, I appreciate the Trogdor reference. Glory to the burninator.

[DeathValleyDazed]

Love the narrator’s presentation skills and the graphics make learning engaging and fun.

[justal]

ABSOLUTE BEST series in a while. Well done, Doc !

[KingsguardRP]

I wish i had resources like this when i was at school. 😢

[pkwrydx]

I appreciate all the works u’ve put to the video! Btw could u please let me know what kind of editing program u use making the video? Like premier pro or after effect?

📝 Summary of Key Points:

📌 All living organisms share the same chemical building blocks, despite differences in size and complexity.
🧐 The six key elemental players in the game of life are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, which form DNA and proteins.
🚀 Carbon is the most common element and forms the basis of organic compounds, creating covalent bonds with other atoms to form organic molecules.
🚀 Oxygen and nitrogen also play important roles in forming different compounds.
🚀 The four major classes of biological molecules are lipids, carbohydrates, proteins, and nucleic acids, which are essential for life.
🚀 These molecules are broken down and synthesized through hydrolysis and dehydration reactions.

💡 Additional Insights and Observations:

💬 "Despite the differences in size and complexity, all organisms share the same chemical building blocks."
📊 No specific data or statistics were mentioned in the video.
🌐 No specific references or sources were mentioned in the video.

📣 Concluding Remarks:

The video highlights the biochemical similarities between all living things, emphasizing the importance of the six key elemental players in the game of life. These elements form the basis of DNA and proteins, and together with other elements, they create the diverse array of organic compounds necessary for life. Understanding these fundamental building blocks helps us appreciate the unity and diversity of all living organisms.

I saw that lighter trogdor reference lol

[yytrhgs]

Great video. I love it! Thank you so much.

[dkaloger]

I prefer the CHONPS acronym, it sounds nicer

[unclebobo]

Hi how's it going watching from Broomfield Colorado

[supertron]

Kinda disappointed that you didn't call the team "Sponch". Rolls off the tongue better.

[JennisChandna]

and the best and perhaps only umpire goes umm a platypus

[sahilsharma]

Yeah but my question is still unanswered. Why is life made up of some specific elements only. Why is Carbon and oxygen alive but iron and zinc not?

[williambilyeu]

Are you wearing that orange hoodie to look like phosphorus?

[larkohiya]

Sigh... Nice information mixed in with unnecessary abstraction. implying intentionally and "goal seeking" from atoms in the rhetoric is just lazy wrong.
