That might have been a custard explosion, but it's also RESPIRATION.
I think the chemical process that keeps people alive is a bit more important and well-known than blowing up a yellow foodstuff, and I am appalled that Helen mentioned the exploding custard. How the hell can that be more in your mind than the very stuff of life?
Honestly it's on the GCSE Science syllabus, people have better knowledge of a useless foodstuff than basic science.
I want an apology.

So do I. Custard, useless? You take that back.

Agreed. To be fair, SF did correctly identify it as oxidation of glucose (strictly speaking, not quite respiration either, it's a simplified representation using only glucose whereas real respiration can use various substrates). But custard??!! Just because custard contains a bit of glucose?!?!? Sad, the ignorance of basic science being shown here.

Also on the A-level syllabus, it's really fun, glycolysis, the link reaction, Kreb's cycle then the electron transter chain.. marvellous fun really. No I mean it.

I have bad memories of A-level Human Biology....perhaps the sciences were a bad career move for me

This reaction, the oxidation of glucose, is widely demonstrated in school chemistry lessons by using custard powder in a tin - you put a candle in the tin, blow the custard powder around through a tube, and get a nice explosion. This is what Helen picked up, and her answer wasn't wrong.

I think exploding custard is much more interesting than respiration. Not as important, granted, but more interesting.

I'm doing GCSE Biology and I didn't have a clue.
I'm peerless on enzymes though. I'll blow you out of the water with my enzyme knowledge.

Go on then, lets have something QI about enzymes.

I know absolutely nothing INTERESTING about them, but I do know about the rate of respiration (it increases to a max, approx 37 degrees and then decreases rapidly as the enzyme dentaures).37 degrees, the rate of max respiration, is the average temperature of the human body.
