    The first thing that got me interested in biology was ATP Synthase...followed immediately by the whole process of muscle contraction. Realizing how much of biology is little machines has just blown my mind. I do wish I would have had your video when I first started learning, it was very "clean" I guess I would say. It was a good overview without too much of the nitty gritty.

    I have a question. At 5:46, you mention the phenomenon of rigor mortis. But: if a sarcomere at rest is RELAXED and NOT contracted, and ATP makes the muscle contract and stiffen/firm up, then by that logic, shouldn't the total lack of ATP lead to total limpness instead of stiffness?
    Also, if during contraction, the I band shorten and the Z discs get closer together by moving towards the opposite Z disc in and center of every sarcomere, what happens in adjacent sarcomeres? Is there a 'center' that all Z discs in the entire muscle, slide towards? Cause there's no way you can move all of them closer while keeping the lengths of the A band and I band the same length.

    Hello and thank you for your amazing videos. I wondered what happens in the sarcomere during an eccentric contraction. So..are the myosin and actin still pulling the Z lines closer together but the titin is stretching to allow the muscle to lengthen? Or is there a gradual sort of slippage between the action and the myosin as myosin is ripped off the action? And what actually causes the muscle 'damage' associated with eccentric contractions? Thank you again.

    • @Corporis
      @Corporis  4 ปีที่แล้ว +4

      δτ Glad you asked. Active force generation is exactly what it sounds like - your muscles use energy to generate force. Passive force comes from an elastic effect _kind of_ like a spring or recoil, but not exactly. This topic might be a candidate for a future video topic as it involves learning the length-tension curve and we could talk about the Frank Starling mechanism, all of which are important, but didn’t fit in this introductory video.
