Proteins (was on the original 2015 paper but they had to use the R paper instead)
•
Ions
1) Co transport of glucose - Na+
2) Na+/K+ in maintaining a resting potential and propagating an action potential across a neurone
3) Ca2+ - synapses
4) Ca2+ - muscle contraction
5) Cl- - maintaining WP in lumen of small intestine (link to cholera)
6) H+ - oxidative phosphorylation in aerobic respiration
7) H+ - buffer system in blood, linked to nervous control of heart rate
8) Mineral ions in plants - lower WP in root hair cell, promote water uptake
9) Nitrate ions, phosphate ions - proteins, DNA
10) Mg2+ - chlorophyll production
11) K+ - cell maintenance
12) Fe2+ - haemoglobin and transport of O2

Importance of the movement of molecules in biological systems Spoiler
•
Movement inside cells.
- Chromosome movement
- Neurones and synaptic vesicles
- Actin and myosin
- Movement through ER and Golgi
- Protein synthesis
- Electron transport chains
- Ion movement
•
The different ways in which living organisms obtain their nutrients.
- Carbon cycle
- Nutrient cycles
- Nitrogen cycles
- Photosynthesis makes glucose
- Balanced diets
- Foetus-placenta
- Xylem: water uptake by plants
-Digestion and absorption
•
CO2
-Affects breathing - could describe Biol1 how the body moves to remove Co2
- Carbon Cycle
- Differences in night time and day time
- Climate change- effect on crops, animal species - distribution of animal species
- Light independant reaction
- Co2 and chemoreceptors
-Haemoglobin and Bohr Shift
- Agricultural farming - greenhouse conditions e.g burn propane to form Co2
- limiting factor in CO2
- causes of increase, agriculture, deforestation (getting rid of carbon sinks, photosynthesising biomass)
