[@naeemakbar2780]

The effect at 04:47 and 05:00 >>>>>

[@vapaus831]

XD

[@nath5415]

does the graph always plateau because of the temperature, and the enzymes denaturing?

[@javadshirinov3750]

If the temperature is to high an goes over the optimum temperature for the plant it will denature the enzymes, which means the active site of the enzyme is changed so it no longer can react with substrates so the enzymes are denatured. Because of the denatured enzymes there is no reaction that is why the line will plateau or even drop to 0.

In quarantine but still studiying ..........🙌🏻

[@Cognitoedu]

That’s dedication

[@mutinycreator]

Thanks a lot, these videos help out a ton. By the way, does the 'higher tier' mean that it is outside of GCSE? As in, if I am only studying for a grade 9 in GCSE and do not plan on taking it after GCSE, do I or do I not need to know the 'higher tier' stuff?

[@Cognitoedu]

You’ll need the higher tier stuff if you’re aiming for a 9 👍

[@not_anii7003]

Higher tier is the tier that gets u from a 1 to a 9, if u wanna maximise your grades learn the higher stuff,if not then do foundation but you're capped at a 5 or 6 I think

[@temsunarolongchar4567]

What is the most important factor?

[@neeldasgupta2441]

all of them mate. one won't work on its own without the other 2

[@nabiha5942]

@@neeldasgupta2441 NOT EXACTLY NO OFFENSE BUT........ACCORDING TO GCSE.....LIGHT INTENSITY IS THE MOST IMPORTANT LIMITING FACTOR ........ SINCE THE REST MAY VARY ACCORDING TO PROPOTIONS........VARIATION IN LIGHT INTENSITY EFFECTS THE RATE OF PHOTOSYNTHESIS :}

[@yancgc5098]

I’d say the most common limiting factor is the most important one which are nutrients. It’s the reason why microscopic algae and kelp forests don’t excessively bloom everywhere in the oceans, cuz of nutrient deficiency

[@inthezone2304]
