So in general what types of questions would an exam with a length of 35 pages ask? More interpreting graphs, or definitions, or explaining processes?

probs more explaining process questions, definitions is more of a 1 mark type of question. Graphs is also highly possible.

But tbh, if you know your shit, doesn't really matter what comes up on the exam!

Hey Guys!
If a question asks to describe the electron transport chain, would this be a good answer?
- Loaded acceptor molecules(NADH and FADH2) are brought to the cytochromes where they are oxidised.
- The energy released is used to form a concentration gradient in which H+ protons in the outer compartment are in higher concentration than the mitochondrial matrix.
- The H+ protons go down the concentration and re-enter the mitochondrial matrix through ATP synthase producing 32-34 ATP.
- The H+ protons are then accepted by O2 to produce H2O.

i just feel like its too long to be an answer, especially under time restrictions. However, i didn't like the VCAA answer in the 2008 exam. So could someone please tell me if i need to cut anything out or if the examiners would hesitate to give me marks anywhere?

Thanks a million!!

What are redundant and universal DNA codes? Questions come up on every exam from the past couple of years but I still don't know what it is?
Thanks :)

Thanks :)

Universal: all known organisms share the same four nucleotide bases (A.T.G.C)
Redundant: there are 20 amino acids and 64 possible codons, so more than one codon can code for one amino acid.

Hey! :)
Okay so an acceptable answer for ETC can definitely be condensed further. So within the electron transport chain:
* Electrons are passed through cytochromes, releasing energy to form 32-34 ATP.
* Oxygen (final-acceptor molecule) accepts the electron, and combines with H+ ions to form water.

That is more than enough, and besides, the new study design really only needs you to know inputs/outputs/locations.

Do we have to mention cytochromes? I've never heard this before.

According to my teacher, they cannot ask us the process of any of the photosynthesis or aerobic/anerobic cellular respiration. We only need to know, for each stage, the inputs, outputs and location. This is what it says on the study design, too. :)

You really don't have to :) I just wanted to condense her answer based on what she had! All you need are inputs/outputs/locations.

best of luck to everyone tomorrow!
Make sure to sleep early and don't worry its just an exam, it will probably be an easier one this year anyway. It is only 35 pages! THANK THE LORD!
Seeya!
