Could it be something to do with affecting enzyme activity?


Original post by dnac5
I put that, and asked my mum whose a biologist and said that temperature is always related to that. We might be lucky

Totally no idea.. I really wanna know that!


Yeah it turned out to be because of the effect of temperature on enzyme activity and metabolic reactions in the body of the shrimp so higher enzyme activity, faster metabolic reactions and faster response to the stimulus

how hydrolysis of ATP provides an immediate supply of energy for biological processes
-energy sourced from glucose is stored in the phosphate bond
- ADP +P catalysed by ATPase produces ATP
-ATP diffuses to cells needing energy (respiring tissue)
- Hydrolysis breaks the phosphate bond
- Energy is released from the bonds and supplied to cells ie. biological processes immediately


Thanks, Edexcel makes the spec point more complicated than it should be.
Is Unit 4 synoptic? I initially thought it wasn't but after doing a few past papers it seems that there are several questions relating to cellulose and even one question on captive breeding programmes? I though the only part which was synoptic was the questions on the article in unit 5. Does anyone have any further info on this?

All of A2 is synoptic, but the majority of the synoptic content is in the scientific article

Typically I'll read the article the day before I do the past paper a few times (probably not the best strategy but hey-ho).

I don't do the questions on the scientific article

Solve the questions without reading the synoptic article, however if the question refers to the paragraph number, I read it then solve the question

What days are unit 4 and 5 this year?


Thursday 16th and 23rd
Guys this may be a stupid question but for real.. How do I answer the questions? for real because I will learn everything and then I answer a question about transcription and it will want to know about enzymes, even after describing every step of transcription. I don't know if you lot get me, but I'm just wondering if there's a plan or anything they look for cos for real I'm bricking it

Read through the mark scheme maybe, and understand what the question is asking before you start writing

I totally get what you mean and I think the edexcel mark schemes are always kinda unpredictable. I think it helps to really look at the wording in the question and how many marks each question is worth and also properly read the mark schemes. Doing exam questions is the best practice I think!

what experiments do you guys think will come up?
The question then says to 'Describe the effect of the ectopic beat on heart activity and suggests an explanation for this effect'
Can someone help with it, I really don't get why there is no change on the pressure in the pulmonary artery and I don't get points 8,9, and 10 on the MS :coma: ?

Thanks..

In the photosynthesis chapter, do I need to cover cyclic phosphorylation and non-cyclic phosphorylation?
I didn't see it in the spec tho :/ and it's confusing tbh
