Question regarding mark scheme: currently doing the 2018 paper 2. For one of the questions I have written down autosomal linkage but the mark scheme says genes are linked and the phrase is not underlined. Would I get a mark for saying autosomal linkage?

ahh they're out :colone:

and yes i'm assuming you would get the mark as long as it's relevant to the question so not sex linkage etc.

PAPER 2 PREDICTIONS:

BOLD/UNDERLINE = 95% SURE
BOLD = VERY LIKELY
* COULD BE USED SOMEHOW IN THE PASSAGE (AT THE END OF PAPER)

• Aerobic Respiration / The Electron Transport Chain *
• Tropisms / IAA
• Animal Movement – Taxis and Kinesis
• Pacinian Corpuscle
• Phosphorous Cycle
• Action Potentials and The Nerve Impulse*
• Muscle Structure
• Muscle Contraction
• Glucose Control / Diabetes
• Second Messenger Model
• Kidney Structure / Production of Urine *
• Inheritance – codominance, sex-linkage.
• Cell Specialisation / Totipotency
• In Vivo Amplification of DNA / ligation / marker genes / replica plating
• In Vitro / PCR
• Acetylation and Methylation of DNA
• DNA Fingerprinting and VNTRs *
• DNA Probes
• Genetic Screening

How accurate are these predictions?

lmao at people who ask for predictions then ask how accurate they are

is photosynthesis likely to come up?? i don't understand it and aqa textbooks don't know how to explain things

does neutral in a mark scheme award you the mark?

no i dont think so its just scientifically right but not the answer they are looking for

I predicted Paper 1 pretty well but, as ever, you never know with AQA. Anything can come up.

For glycolysis, do you know if AQA accept glucose -> glucose phosphate -> hexose bisphosphate -> 2x triose phosphate, etcetera. This is instead of glucose -> phosphorylated glucose -> 2x triose phosphate, etc. It's just easier for me to remember what happens with ATP during glycolysis from this and if a respiration essay title comes up its two easy extra terms. But obviously I wouldn't want to lose a mark if we have to describe the stages of glycolysis and they only look for phosphorylated glucose - do you know if this is the case?

Maybe try to go over all the previous one and see how the mark scheme is looking for

It's all about how well you apply the context. The questions are very tricky there and the mark schemes are undeniable harsh.

Just engage with the terminology used in the passage. Make sure you get the passage first then try to answer as specifically as you can. The more you do the faster you get. Read through every part carefully.

Glycolysis is very complicated in reality and the term "phosphorylated glucose" is an umbrella for the many many compounds that are before pyruvate.

As the science is correct, you will not be under marked.

But, if they ask you to complete a flowchart or some sort of diagram with the words, they'll be looking for triose phosphate and phosphorylated glucose, rather than fructose bis-phosphate and all the other complex words. It'll depend on how they word the Q.

I doubt you will be asked to describe glycolysis as it's too simple - they're more likely going to use some deformed practical. As long as you understand the concepts behind it, i.e. that pyruvate needs to be formed as only it can cross mitochondrial membranes and not glucose, and that there is a net positive change of 2 ATP, you should be fine.
