Biology A2

1. Glucose->2xTP
2. Using 2xATP

1. TP->Pyruvate
2. ADP + Pi -> ATP
3. NAD->redNAD

1. Low temp.
2. Dry to constant
3. Carbon is ~50% of dry mass

1. Total amount of chemical energy convert by plants from light energy

1. ~50% of GPP lost as plants respire
2. NPP=GPP-R

1. Nitrogen compounds converted to ammonia
   1. By saprobionts
   2. In dead organisms
   3. In urine and faeces

   1. But can become cancerous
2. Fiborous
3. Cause blocakges
4. Slow growing
5. Pressure on organs
