Miss A wrote on the board
CO₂ + RuBP → 2 X G3P
Kath asked “Miss A, what if O₂levels higher than CO₂?”
Naveen threw eraser at me, it whack my head, I woke up....
At Gma’s house, was left alone, no internet access, friend from outstation smsed, told her my dream
“Lava, RuBP takleh kowt react ngan O₂...mesti CO₂...kalau tak, mampos la pokok tuh takde glucose!”
“Ye la...tapi kalo O₂lagi banyak? Pokok tuh nak buat aper?”
“Aha kan? Kalo photosynthesis dah melampaw, takkan O₂ tinggi skit takleh handle?”
“Hah, kalo ngan CO₂ product dier keluar 6-carbon compound kan? Pecah kan dpt 2 X (3-carbon compound) G3P, cam dlm Calvin Cycle.... Kalo O₂ jerh, 5-carbon compound jerh la...”
“5-carbon atok kaw...nak buat 2 X G3P tak cukop!”
“Buat satu jerh la...yg lagik 2 carbon tuh...jadi something la..plant poop kerh? :P”
“Melampaw kau...tapi kan, logic jugak equation ko tuh...I raser-raser boleh ah, tapi kadang-kadang ko tuh kalau tak merepek tak cam!”
“Jap I tanyer kawan2...nanti I bagi taw...”
So, I smsed everyone...and their replies? (exact words)
“Maybe CO₂ s given out...I read it somewhere, possible, true...”
“Shut the fuck up Lava...tell me when you figure that out”
“Hmm,no,quite sure it’s no...if RuBP could react with O₂, then trees couldn’t live in O₂rich areas anymore as no glucose can be produced...makes sense?”
“I think it’s a self sacrifice mechanism...never heard of such reaction...besides...I’m doing arts Lava”
“The trees you’re talking about came from outer-space, from a distance planet where everything is a reverse...you watch too much TV”
“You mean Rubisco breaks up RuBP for no reason? Mad ah? O₂is evil if that’s the case”
“I’m asleep la...ask my dog...but tell me later when you got the answer from him...”
“No way, photosynthesis evolved in atmosphere with far more CO₂than we have today...it’s in their genes, Rubisco can only catalyse reaction for CO₂and RuBP...ok honey?”
So, I asked someone who ‘might’ live on a far (and remote) away land...
“Weyh Lava, I tak ambik Bio ah...maner dak I taw?...alrite, jap, I pegi find out utk you, janji ko belanja makan...”
20 minutes later...
“lava sah equation ko yg merepek tuh, ambik pensel catat...
Enzyme yang catalyses reaction between RuBP ngan CO₂, Rubisco kan? Can also catalyse utk RuBP ngan O₂...So, O₂ngan CO₂compete ah utk active site yang samer...biler O₂ level high and CO₂levels low, yang reaction ngan Oxygen yang difavourkan...
Tengok nih, I tak paham, You salin and tengok...
O₂ + RuBP → Glycolate (2-carbon compound) + G3P
Compare ngan Calvin Cycle
CO₂ + RuBP → 2 X G3P (2 X 3-carbon compound)”
“Glycolate tuh aper?”
“Entah...yang 2-carbon compound tuh kowt...tapi kat sini dier kata glycolate cannot be fixed into carbohydrate, and instead passes into the mitochondria where it is respired...process nih nama dier photorespiration...”
“Orite....so photorespiration nih rugi ah, nanti photosynthesis tak efficient...boleh overcome kerh benda nih?
“Boleh...nah, some plants have overcome this problem...C4 plants?! WAKAKAKAKAKAKA!!”
“Serious kerh ko nih, C4 tuh stand tok aper?”
“Entah...pfft...tak tulis...tapi C4 plants overcome photorespiration ader bundle sheath cells that have different chloroplasts...C4 *giggles* “
“Boleh meletup kerh *ahahahahaha* C4 plants tuh? Serious ko bacer dr maner nih?”
“Meletup nenek kau, example of C4 plants: sugar kane, maize and millet...ko makan tebu meletup tak? I bacerkan dari buku Bio roommate I....dier ader buku bio tebal giler mak dier belikan...tak pernah bacer pon, buat action jerh kowt...”
“HAHA, perisa meletup!! Orite ah...taknak kacau, gi tido ah, kang kena marah kang! Tangki punyer mak (thank you very much)”
“alrite, byeee..belanja tau”
Janji Tok Hajji I’ll never question nature again, you ask one question, she’ll give you some mojo and more questions...
And what started as a joke...turns out to be real...I couldn’t stop laughing eventhough it was scary...because we got high and made up an equation based on simple maths which sounded quite logic...
Oh, check out ‘photorespiration’, here, knock yourselves out...

Now...how the readings would be affected when we use kulit manggis instead dalam beetroot experiment...some questions are best left unanswered....
