What codon & amino acid is a start |
Methionine AUG |
|
|
What binds amino acids to tRNA |
TRNA transferases |

|
Sickle cell anaemia cause |
- single substitution, glutamate (hydrophilic) replaced by valine (hydrophobic) -valine side chains interact and cause long fibres of stuck together Hb molecules to form |
|

|
Productivity |
The rate at which plants convert light energy into chemical potential energy |
|
|
Describe the succession of glacier bay |
1. Moraine exposed 2. Pioneer plants mountain avens inhabit (N fixing) 3. Pioneer plants produce humus -> soil, holding in water, mineral ions and rock particles, stabilising soil. NH4+ seeps into soil 4. shrubs like the alder shrub inhabit due to soil (also n fixing) 5. Alder shrubs lower pH due to acidic humus (was pH 8 due to rock carbonates, now 5) 6. Pioneer plants die and conifer trees like Sitka spruce inhabit 7. If drainage poor, sphagnum mosses take over as they lower pH further by making soil more waterlogged. If not, spruces remain |
|
X, Y, nitrogen fixing bacteria and substance it releases |
X Nitrosomonas Y Nitrobacter Rhizobium Lectins |
|
|
What is ammonification |
Organic nitrogen in soil (from dead organisms and waste eg urea) being converted into NH4+ compounds by decomposers |
|
|
-How are the anaerobic conditions rhizobium needs created -what does it do |
-plant produces protein leghaemoglobin -nitrogenase enzyme N2->NH4+ |
|
|
3 activities of the ANS |
1. Controlling smooth muscle 2. Controlling the rate of cardiac muscle contraction 3. Controlling the activity of exocrine glands |
