[@Biologywithrasheed]

Dear you said that six carbon are used in the reaction but it also brings 12 oxygen mean one Carbon dioxide have two oxygen six of them are used in making of glucose but what happened with other six oxygen ??

[@hussainbiology]

Cycle Runs Six Times actually.... On Every Cycle 1 Carbon is fixed and one Oxygen molecule is generated .. So when 6 Carbon Dioxide molecules are fixed we get 6 Oxygen molecules as well... ( How come 12 Oxygens are generated )

[@Biologywithrasheed]

@@hussainbiology this is dark reaction there is no oxygen formation

[@Biologywithrasheed]

@@hussainbiology that oxygen form in the light reaction

[@Biologywithrasheed]

@@hussainbiology No reply dear why????

[@hussainbiology]

@@Biologywithrasheed The Glucose Molecule is made up of 6 Carbon atoms , 12 Hydrogen atoms and 6 OXYGEN atoms ( So if you balance the equation u can easily generate what has been said in the video , I hope this helps)

[@YankeeMYwankeee]

How does a 3 carbon go back to being the 5 carbon R1,5 bP????

[@tfyouneutrallittlebody4751]

A 3 Carbon atom chain is called a PGA. With a hydrogen atom affixed to it it's called a G3P. If you think of the Calvin cycle as 6 units working simultaneously, we have 6 Carbon atoms from each unit and 30 more too from the RuBPs (cause 1 RuBP = 5 carbons) there are 36 carbon atoms. Out of those we only need 6 for glucose, then we have 30 to spare. Think about the 6 units. Each unit's RuBP needs to be recreated in order for the cycle to continue. So we need 5 carbons in all the 6 units to recreate the RuBC which is 30 carbons in total, which is exactly how many we've got left after making the glucose

[@adenzewdu3564]

Why does 3 Calvin cycle has to take place inorder to produce 1TP??

[@creativealishka155]

excuse me sir Carbon fixation pathway and Calvin cycle both are same ya different...

[@hussainbiology]

yes.. this Calvin Cycle is a Carbon Fixation pathways ( but we have other fixation Pathways in Archae too but this Calvin cycle is the major Pathway for carbon fixation)

[@gurimusic5587]

in regeneration phase there is only *3 atp* consumed not 5 to convert the 5 molecules of Glycereldehyde 3 p into Rubp.... why?

[@doctornorthern]

On conversions of 1,3 Bis phosphoglycerate to Glyceraldehyde 3 phosphate. Happened due to reduction,where went the remaining phosphate molecules?.. All the more during regeneration.. How 5 Molecules with 5 Phosphates got 3 ATPs(phosphates) and became RuBP

[@loramaeduale5764]

First of all thank you so much that photosynthesis becomes clearer to me ONLY until sa part of 5 mol of G3P regenerate to RuBP but as written in your representation 1 mole of glyceraldehyde will produce sugar? But I was wondering how will it become sugar with C6H12O6 if glyceraldenyde has only 3 carbons? I want to know how it produce a sugar with C6H12O6.

[@hussainbiology]

The cycle runs two times , to get sugar molecule...... ( triose + triose )

[@SouRavMuRs]

For the formation of glucose,6 carbons are required. Single cycle gives triose phosphate which have 3carbons. So it needs 2cycles to produce glucose. But why here it says that for the formation of glucose 6cylces of calvin cylce are required ? I didn’t get sir ! Can you please help me out ?

I have a question ? One of my friends was saying that the plants produce ATP and NADPH in light reactions and plants can make these two compounds without the dark reactions. It is pretty obvious that the products of light reactions are utilized in dark reactions for glucose formation and dark reactions depend on light reactions. So, Does light reaction also depend on dark reactions ? Can plants make ATP and NADPH without the dark reactions ??

How many inorganic phosphate are produced in calvin cycle???

[@hussainbiology]

this Calvin cycle in nature actually runs 6 times to make 6 carbon compound ( Glucose ) Now like in my video i have taken 3 Carbon dioxide atoms first , that means this has to run 2 times to make glucose molecule . ( 3 Carbon dioxide makes triose phosphate , then again 3 Carbon dioxide makes triose phosphate = finally yielding us Glucose 6 Carbon compound.
