    Tysm for included the point on oxygen debt because I have been so conflicted wherever anaerobic respiration would be necessary to include as it wasn't on the indicative content

    Hi miss H I think that you should do a playlist explaining each sections in the topics for example enzymes that would get a lot of view takes time but definitely worth it

      I wish there were more hours in the day! 😊 I'll do what I can in between my assessment marking! 🤞

    Would I get the mark if I said CARBOHYDRASE was the enzyme that digests starch in the human digestive system?

    Hi. I know that this is very late, but isn't oxygen a product of respiration in plants (photosynthesis), not a reactant? Does that mean that oxygen isn't required for respiration in plants?

    • @BiologyBreakdownwithMrsH
      @BiologyBreakdownwithMrsH  3 місяці тому

      Respiration and photosynthesis are different reactions. Plants carry out photosynthesis in the light but they carry out respiration all of the time. Photosynthesis in chloroplasts, respiration in mitochondria. Good luck 😊

    Will I get the mark if I just said iodine and Benedict

      Maybe? Are you referring to leaving the word solution out? best to put iodine solution or Benedict’s solution if you can remember 😊

      Would you recommend anybody for Physics & Chemistry because i would certainly need the same layout as learning as it is on here.

      I thought PMT did but I can’t see any videos. Cognitio are very good, not sure if they do exam question practice though?
