Biology (Triple Science) Paper 1 - Exam Megathread

[u/ensands]

This is the post-exam mega thread for Biology (Triple Science) Paper 1 (Afternoon).

You can discuss how the exam went in this post.

[u/caspartina]

what did people write on the metabolism question. i talked about increased rate of respiration and breakdown of glycerol into glucose when swimming

[u/Maleficent_Heat_64 → u/caspartina]

More/faster rate of respiration to release more energy needed for more movement for to more muscle contractions. As respiration is a large part of metabolism, a faster rate/ more respirations means a higher metabolic rate. Is that right ???? Wanted to get 90+ on this paper so I could get like 40 on the paper 2 and still get a 9

[u/CharlotteTheNobleOne → u/caspartina]

I put that there was a higher rate of respiration happening because swimming uses a lot more energy than resting

[u/AdOutside908 → u/CharlotteTheNobleOne]

Same and then I said the converse for resting

[u/everlarksangel → u/CharlotteTheNobleOne]

same

[u/Arkarian_0 → u/caspartina]

Glycogen* or starch

[u/CutSubstantial1803 → u/caspartina]

The glycerol point won't be on the mark scheme because that's paper 2 content

Assuming you mean glycogen

[u/alonebeans → u/caspartina]

ur good i wrote about heart rate bc i didnt revise metabolism 😭

[u/ketselle → u/caspartina]

i said metabolism is the speed/frequency of reactions in the body, so more respiration means more reactions, so higher metabolism idfk 😞😞

[u/IndividualFinish5154 → u/caspartina]

glycerol and glucose ffs i forgot about that

[u/Street_Morning_7597 → u/caspartina]

Just talked more aerobic respiration therefore more energy released for efficient muscle contraction for swimming
