Lipids dont store energy. They are used as energy, yes- but they dont store them. Hence, they supply energy. Your reasoning is correct- your answer is wrong.



Lipids DO store energy!!!
Adipose tissue => 3 carbon molecules => respiration

they store DOUBLE the energy per gramme of carbohydrates

They certainly do not travel through the RER, as they are synthesised on the SER

For the cholesterol question i had two points


-Cholesterol prevents cell membrane liquidification at high temperatures
-Cholesterol prevents cell membrane solidification at low temperatures

Gah, the more I think about it, the harder this exam seems. I would have lost so many marks And I had a chemistry class in the afternoon and I couldn't concentrate, then I got 62% on it and I was so angry. I don't think chem is going to be too good tomorrow.

cholestrol questionnnn

[lukeperry91]

For the golfball question, was 1. receptor and 2. connecting neurone
? im sure 2. was connecting neurone as a neurone is a brain neuron and it was in the brain, but now im doubting whether or not 1. was the effector or the receptor and was the receptor actually the retina/optical nerve junction

[veno]

I had 2 as connecting neurone too but 1 was the effector, it was pointing at the muscle that controls the eye lid and therefore the response (blinking at the ball).. not the eye itself

[hard]

For the golfball question, was 1. receptor and 2. connecting neurone
? im sure 2. was connecting neurone as a neurone is a brain neuron and it was in the brain, but now im doubting whether or not 1. was the effector or the receptor and was the receptor actually the retina/optical nerve junction

same

[lukeperry91]

so 1. was receptor? now that im looking at it again it seems more logical that 1. is actually the effector as it looks muscle-y
