Hello again :) I did a quick search of the forum but couldn't find an answer to my question so I figured I'd ask it in case anyone else wanted to know as well. To what extent are we required to know about apoptosis? Do we need to know about Bcl-2 or Apaf-1? Many thanks!

You just need to know the general process i.e. Extracellular signal or mitochondrial signal - Caspases cleave the cytoskeleton - cell collapses and forms apoptotic bodies (also called blebs) - the apoptotic bodies are engulfed by phagocytes and the contents recylced.

Even this might be too much, but hard to say with only one exam behind us!

Heyo,
Just wondering, are the following still in the study design/do we need to know about them?
- Indole Acetic Acid (IAA) & apical dominance
- Photo/geo/positive/negative -tropism

Nope. Just know the classes of plant hormones and their general function.

Hello guys,

I have a Biology SAC in which I need to design a prac, carry out the experiment, then present the results in the form of a poster.
Should the methodology be written in a paragraph form or should it be listed in numbered steps?

Thank you  :D

I'd suggest writing it out in listed numbered steps - since that makes it much more clearer than just a large paragraph

Numbered steps is fine. Just remember to make it past tense (i.e. say 'this happened' not 'do this')

Edit: Beaten again  :o

There's this button at the bottom of the page that says 'notify'. I get an email whenever a new reply is posted. I assume darkdzn clicked it too. But yes i'm pretty much on here 24/7 anyway haha

Hey guys,

What are the inputs and outputs of the three stages of aerobic respiration (glycolysis, kreb cycle, electron transport chain)?
I've read my textbook as well as online but the exact number of molecules are different.
Also, how much ATP is produced by the ETC and aerobic respiration as a whole? I have heard that there is disagreement over the number of ATP produced.

Thank you! ;D

Hey
So for the exact numbers of inputs/outputs of the various stages does have some discrepancies between different sources so if you want to memorise them, then memorise the ones that your teacher gives you - otherwise don't worry about it since you don't actually need the memorise the exact number of the inputs (e.g amount of NAD input)

Glycolysis
Input: Glucose, NAD, ADP +Pi
Output: Pyruvate, NADH, 2ATP

Krebs Cycle
Input: Acetyl CoA (or pyruvate however there is actually a transition stage which converts the pyruvate into Actyl coA prior to entering into the krebs cycle), ADP +Pi, FAD, NAD
Output: CO2, 2ATP, FADH2, NADH

Electron Transport
Input: NADH, FADH2, ADP+Pi, O2
Outputs: NAD, FAD, 34ATP, H2O

So 2+2+34 = 38 ATP produced in total
However, of course, in reality this ideal 38 ATP produced is not always the case as the cell can "lose" pyruvates or possibly expend more energy in adverse conditions etcetera. Despite this being said, in past VCE exams, I've seen that they've generally accepted a range of answers e.g. 36/38. Although it is best to just stick with whatever your teacher tells you
