Which stage of the nitrogen cycle does the above equation represent?

Which process can occur due to the actions of Nitrobacter bacteria?

Many decomposers secrete enzymes to digest organic matter, then absorb the products they require. The digested products which are not required remain in the soil. The digestion of which organic substance will result in the presence of ammonia in the soil?

In a woodland, 8,150 kJ m^-2yr^-1 is lost as heat from respiration. The gross primary productivity of the wood is15,000 kJ m^-2yr^-1. What is the net primary productivity of the woodland?

Which would be the most accurate method of sampling dry biomass?

The diagram above shows one form of anaerobic respiration, name molecule 'Y'.

Is this the correct equation for anaerobic respiration in yeast cells? : Glucose → Carbon Dioxide + Water + Ethanol

Is the column for Krebs in the above diagram correct?

How many molecules of ATP are generated by oxidative phosphorylation in the ETC from one molecule of glucose?

As the ETC flows, what will happen to the pH of A?

Isocitrate dehydrogenase is an enzyme used in the Krebs cycle to convert Citrate into the 5C intermediate. IDH1 is an inhibitor of Isocitrate dehydrogenase. What would happen to the concentration of Acetyl Co A produced by cells exposed to IDH1?

Isocitrate dehydrogenase is an enzyme used in the Krebs cycle to convert Citrate into the 5C intermediate. IDH1 is an inhibitor of Isocitrate dehydrogenase. What would happen to the volume of Carbon dioxide produced by cells exposed to IDH1?

Which two processes turn Citrate into the 5C intermediate?

Molecule B enters the Krebs cycle from the link reaction, what is it ?

What is represented by molecule C?

In the above experiment, chloroplasts were isolated from plants grown at different light intensities. In each trial scientists collected oxygen for 15 minutes. Calculate the difference in oxygen produced from mutant plants at low and high light intensities at a light intensity of 500 μmol photons m^–2s^–1. Measured in μmol O2 mg^–1 hour^–.

Other than temperature and pH, give two factors that the student should keep constant in the above experiment.

If six molecules of molecule C are produced, how many will be regenerated into substance A?

In non-cyclic photophosphorylation, the electrons that leave the chlorophyll are replaced by the splitting of water. What is the name of this process?

Name structure E
