1. Water is a non polar solvent
2. Conjugated protein. Has both proteins and lipids conjugated as a bond.
3. Auxin induces stem elongation
4. Pyruvate or pyruvic acid is the substrate on which alcohol dehydrogenase to produce alcohol
5. Lactic acid. This is reverse fermentation reaction
6. Oxygen. In electron transport chain, oxygen is reduced to prove water.
7. Carbon dioxide
8. Oxaloacetate combines with acetyl coA to give citric acid which is metabolised to oxaloacetate in Krebs cycle regenerating oxaloacetate.
9. The glycerol is the non fatty acid part which is converted to dihydroxyaceton phosphate DHAP which enters glycolysis to produce pyruvate
10. Exergonic. Energy is released.
11. G-6-P is eventually broken down into one DHAP and G-3-P both of which produce pyruvate. Hence one glucose 6 phosphate produces 2 pyruvate molecules
12. One phosphate at 6th carbon
13. Pyruvate is 3 carbon molecule which is converted to 2 carbon molecule- acetyl coenzyme A.
14 . Carbon dioxide is produced.
15. Acetate
16. Auxin in leaves cause abscission i.e. cause them to fall
17. Yyss. The recessive trait has to be in homozygous condition to express itself.
18. Water. Photocatalysis of water produces oxygen and two protons which reduce NADP+
19. 3 carbon molecule, it is also called a c3 cycle
