At 5:40 why is it because all the substrate has been used up, can it also be because not all the substrates have been used up because the enzymes have denatured?

[@willowinnit1169]

Do you mean for 25° or 37°?

Fantastic. The question paper on Tes is missing a diagram for Q1

[@BioTeachLondon]

Hi there, I just checked the document on TES and all seems ok for this document for Q1. Were you not able to access the image when you downloaded the question pack?

[@allisoncurrystaff2986]

@@BioTeachLondonHi, thats a quick reply. On TES it seems to be in a RTF format that doesnt have an image for Q1. Some of the others are word that work ok. Perhaps its a problem my end

[@BioTeachLondon]

Allison Curry (Staff) ah yes! I’ll change that today and let you know when it’s done. Hopefully a .doc will not cause any issues!

@@allisoncurrystaff2986 Hi there! I've changed this to a word document now. Let me know if you encounter any more problems :)

Thanks a lot

[@maserekashepherd7484]

The rate of reaction gets constant coz of complete saturation or exhaustion of substrate. What's most correct biologists?

[@hoyama1520]

Thanks, this is very helpful

thank u maam

[@BioTeachLondon]

You’re welcome!

How is the awnser 2.5 for the rate of reaction?

[@lubnaismaili8848]

They changed the time from seconds to minutes 10/(240/60) = 2.5

but why?
