    Wow - that's so interesting that to learn that microtubules form the cilia of the epithelial tissue in respiratory system. I knew one of its function was to be a track for motor proteins like kinesin but never put the two and two together. The microtubule is usually found in the cytoplasm. Aside for being a track for motor proteins, it is also involved in the mitotic spindle (like you explained) and mechanical support. Some relevant components of the mitotic spindle are the centrosome, astral microtubule, kinetochore microtubule, and overlap microtubule, kinetochore, sister chromatids, motor protein, and spindle pole. It is a stiff, hollow, and the largest fiber that resists compression. I also learned that protofilament from your video is a row of a tubulin subunit and two of them is a heterodimer graph. The circumference of tubulin subunit is called the lamen. A common motor protein that a microtubule carries is called the kinesin, which is head, taiil, and stalk. The kinesin carries the transport vesicle across the kinesin using the energy from atp which becomes adp and p.

    On a certain level, we have a drug store in our microtubules, the neurochemicals that show up in flow: so dopamine, norepinephrine, anandamide, endorphins, and serotonin. If you were to try to cocktail the street drug version of that, right, you're trying to blend like heroin and speed and coke and acid and weed- and point is, you can't do it. It turns out the microtubules can cocktail all of 'em at once, which is why people will prefer flow to almost any experience on Earth. It's our favorite experience. It's the most addictive experience on Earth. Why? 'Cause it cocktails five or six of the largest pleasure drugs the microtubules can produce. We're all capable of so much more than we know. That is a commonality across the board. And one of the big reasons is we're all hardwired for flow, and flow is a massive amplification of what's possible for ourselves.

    Good description of what they're doing, but HOW do they know WHEN to start forming, and WHERE to start & end???
    And how on earth did they form before the first living cell existed? (And the same question for the thousands of other molecular machines necessary for cell-life)!
    And if they DID form before the first living cell (as they ARE necessary for cell-life, correct?), then WHY aren't they found forming on their own in nature today?

    when does GTP bound tubular hydrolyze? is that just a matter of time and when the mitotic spindle reaches kineticore it releases kinesin13 to destabilize it to prevent continued lengthening? and it would happen (the degradation) if xmap215 and other MAP catalysts that sped up lengthening were slower??

  • @winstonsmiths2449

    I am an Intelligent Design believer. How would mutations account for this type of development? Where is the information created that tells the organism that a new, never before existing cell is being formed and it needs to know what it is, how much to grow, shape and proteins needed. Sincere question.

      To form the first ring of the microtubules is the hardest and slowest step so it skips that, that's why it's faster with a preformed gamma ring

      @@BeingCurious101 Energy (electricity) in nature seems to mysteriously propagate from the quantum realm. Therefore our brain’s electrical properties and functions are fundamentally interfacing with the quantum realm by default. Consciousness seems to be something entirely separate from ourselves and drawn from the quantum realm through microtubules which acts out physically through our genetic predisposition. Whatever reality exists in the quantum realm for us manifests into physical matter through our thoughts, in a balance of free will and super-determinism. A lot of spiritual teachings explain this parts of this concept much better. Why is this seemingly true? I have no idea yet. How do microtubules objectively function in that esoteric manner? I have no idea yet. These are my speculations however..

      @@gregoryallen0001 tiny black holes would be an impossibility but microtubules are definitely interfacing with a very fundamental aspect of the natural medium which is contingent upon the properties of spacetime like you mentioned. I think the answer of where consciousness comes from lies in the properties of empty space since an abundance of energy propagates through the void of ‘absolutely nothing’ at all times (through time). The question is where and why do quantum fluctuations (waves) occur which manifest into energy at that very fundamental level and come into existence in this realm of spacetime in the first place. Wherever that is; (if it can even be described as a location perhaps even beyond time) is where all living consciousness derives from. I believe our microtubules are interfacing with the energy derived from the medium empty space itself. I hope I articulated that in a way that makes sense. I think all of humanity should be tackling these types of topics regardless of expertise to see if intuition plays a role.
