Biology- Homeostasis and Signalling molecules SAC HELPPPP!!

[sabii]

Just on the topic of things that are no longer in the scope of VCE. Everything to do with negative feedback and positive feedback and plant hormones are no longer apart of VCE anymore with the introduction of the new Study Design. I suppose it is just a result of dumbening down the course after they took out the Mid-Year Exam 

Really? Wow, is signalling molecule and signal transduction still on it?

Really? Wow, is signalling molecule and signal transduction still on it?

Signalling molecules and signal transduction is still required knowledge but we don't need to know every step in the cAMP pathway, I think. Just generally.

I also think negative feedback and positive feedback might be in it because it relates to the stimulus response model.

Here's what it says on the study design for this part:

• coordination and regulation at the cellular level:
– the nature of the stimulus-response model and the roles of the nerve pathway and chemical signals in the transmission of information from receptor to effector

– types of signalling molecules: neurotransmitters; animal hormones; pheromones; plant growth regulators

– a generalised view of how information received by a cell’s receptor is transducted to an effector to initiate various cellular responses including the position of receptors for protein-based and lipid-based signalling molecules

– apoptosis (regulated cell death) as an example of a cellular response to specific signals
