    This is awesome, I never quite understood this unit until I watched this video for cramming for the exam tomorrow, thanks for this!!

    Thank you for all your videos! I have 2 hours until my AP Bio exam right now and I'm watching your videos to cram lol.

      i got a 4! i could’ve done better if i studied more/ahead of time, it was just hard with all the ap exams all at once. def recommend making a study plan for how you’ll manage your time studying for each if you’re taking multiple and don’t wait nearly as long as i did to start.

      And is biomass coming

      Animal systems are not in the curriculum BUT it can be used as an illustrative example. It will focus on the biology and any of the anatomy information will be given. Biomass is fair game.

    what happens to the pyruvates after glycolysis?

    • @apbiopenguinsinsta-review4538
      @apbiopenguinsinsta-review4538  6 หลายเดือนก่อน +1

      They lose a CO2, decrease in energy as NADH takes an electron to the ETC, and an acetyl CoA is added before it enters the Krebs cycle and is completely broken down into CO2 (while continuing to release its stored energy)

    in glycolysis for nad, does it gain an electron to become NADH?

    • @apbiopenguinsinsta-review4538
      @apbiopenguinsinsta-review4538  6 หลายเดือนก่อน

      Yes, I am not sure of the full chemical interaction but it gains the electron and a proton.

    3:38 should we learn about the formula for ap bio because i never heared of it before 😢

    • @apbiopenguinsinsta-review4538
      @apbiopenguinsinsta-review4538  7 หลายเดือนก่อน +1

      Nah. It was removed from the formulas sheet but it helps explain exergonic and endergonic.

    Can you explain the answer to the mice question

      Did I not answer it during the video? I scrolled quickly to figure out where in the video you are referring to, but I’m not sure what question you are talking about.

      @@alamofour1514 gotcha. I just a quick search on Google and it looks like it is just the Endothermy, they need to maintain body temperature which results in more respiration to generate the heat.
