  • Who sings this song?

  • The song is called 'A-Punk' by Vampire Weekend.

  • Can you explain to me the bit about TP forming glucose on every 6th turn of the cycle. I cant work out the numbers in my head, does every turn of the cycle start with the 12 CO2 and 12 RUBP?

  • Yeah, sorry about that. This is actually 6 turns of the cycle, the reason i did it like this is so i could show that glucose is made once every 6 turns. Each cycle starts with 1 CO2 (1C) and 1 RuBP (5C) which form 2 GP (2x3C), then 2 TP (2x3C) which can then either make 1 glucose (6C) or 1 RuBP (5C).

    Hope thats helped. :)

  • Yeah it really does =]

    So the 6CO2 enters the stroma just from the atmosphere? and reacts with the 6RuBP that is already there? then they react to form 12GP which are 3 molecules of 12 carbons?

    is it only the ATP and reduced NADPH that comes from the light dependent reaction to help make 12 GP into 12 TP? is that right?

  • Noooooo! There are 12 molecules of GP, each with 3 carbons.

    And yeah, youre right about the rest of it, its only ATP and NADPH + H+ that are from the LDR. :)

  • My Biology exam is next week, what a lifesaver! And is it weird that I was listening to this song while I was revising? :3

  • Doesnt Co2 combines with 5 carbon compound

  • whats gp!!!

  • thanks for this! perfectly simplified - and the song is calming my nerves a bit for the test in 2 hours

  • Wow thanks you're a ledge (: (: (:

  • @chxdst agree :(

  • hahaha i was rofling as i watched this. thanks so much! it made bio fun...ish.
