Was the reason why enzymes speed up reactions that it allows activation energy? Or did you have to say more?
Its because it lowers the activation energy so there are more enzyme substrate complexes are formed so increases rate of reaction I think. I think just writing lowers activation energy may get you the mark.
Damn it, I wrote that enzymes can form more enzyme substrate complexes after releasing the product so they have a high turnover number and can form lots of products per minute. Is that right also or?

Technically it's right but I think to get the mark you might have to say something about lowering activation energy. Cant be too sure though. Just hope you get a lenient marker!
I put that the enzymes themselves are insoluble because they're globular proteins, and then that they'd be too spread out if not clumped so there is less chance of a successful collision>enzyme substrate complex>product made so there would be a lower rate of reaction. Probably wrong though, it was a complete guess.
Enzymes/ globular proteins are soluble though? Fibrous aren't.
I said that when a substrate bonds to an enzyme, the enzyme alters shape slightly and this distorts a bond in the substrate, lowering the activation energy required to break it.
for functions of protiens did you write intinsic used for movement of ions and large molecules across membrane via facitlaltated diffusion and active transport and glycoproteins on outside act as recognition sites
I put root tip for the mitosis tissue one. Could everyone find TWO differences between the two ER photos. I wrote one is rough-with ribosomes and the other is smooth-without....

Same, it was only 1 mark like the rest of the photograph questions
Do you think for the DOX question it would be sufficient to say that the proteins change shape therefore cannot function in channeling key molecules like magnesium?
