AQA Biology Module 8 18th June... Watch
Digestive ones: Secretin, Gastrin, CCK-PZ
Ovulation: FSH, LH, Oestrogen, Progesterone
Respiration: CoA,NAD any others?
Photosynthesis: RuBP*something*, NADP (i don't know the name of this hormone anyone?)
Hormone recogntion: glycoproteins on the cell membrane
Water Regulation: ADH
Anything else? We don't actually cover what hormones are made from do we?
Can we not talk about hormones in a similar way to enzymes, tertiary structure etc. Also i've got a revision guide that mentions thyroxine which increases metabolic rate BUT i think they jsut forgot to edit it out between writing module 6 and human bio module 7
Oh my gosh! Sophiesomething you did exactly the same a levels as me! Biology, Chemistry, maths and even critical thinking (which my school forced me to do!!). Anyway....just saying good choice! Cell mutation doesn't allow for much range though.
lol. Mutation is my forte I guess. *shrugs* - anything else and I'm a bit screwed.
Yeah. I sort of had critical thinking thrust upon me too - anyone who did well at GCSEs/AS and was dropping a subject at A2 had to do it. Never mind, I actually quite enjoy it.
Hmmmm....i don't do unit 8. I think you're on spec B perhaps? Am i right in thinking adenosine triphosphate (ATP) is exactly the same molecule of a nucleic acid? ie. Phosphate - pentose sugar - connected to a adenine base? You know, the backbone of DNA with an adenine base? A
its the essay thats worrying me the most, ive never been able to do them. it takes me about 4 hours to write an ok one with my textbook open in front of me let alone in 45 minutes all on my own! anyone know how you go about revising properly for this part?
• Lipids (the only unit 1 nutrient not yet done)
• Gaseous exchange
• Nucleic acids
• Protein synthesis
• Genetic engineering
• Active movement across the membrane
Write essays on a couple of those, i don't bother actually writing the essay, just the plan to see if i could draw upon all areas of the specification. If i can't remember a certain part, i read my revision guide in awe!
This may be a bit stupid but can someone help me out with what sort of things are included in each of these topics?
Biochemistry - Respiration, Photosynthesis etc. etc.
Genetics - Meiosis + mitosis (they overlap), polgenic inheritance, variation, mutation, DNA synthesis etc.
Physiology - Liver (glucose control), Kidneys (water), Lungs (oxygen), Heart (blood!!duh), ectotherms, endotherms
Ecology - Succession, line transits, mark + release, deforestation, nitrogen cycle, carbon cycle
That's just a bref overview.
There was no genetic question, no nervous control of heart, no natural selection and evolution and no ecology.
