Know the key molecules in glycolysis and the TCA cycle that can lead to products that are important for producing molecules needed by the cell. Briefly describe the cellular location of the oxidative pentose phosphate pathway its relation to glycolysis. Describe the structural similarities and differences between glycerolipids and glycerophospholipids. Describe generally where and how these types of molecules are produced in the plant cell. Explain what this means.
Nitrogen fixation can occur in organisms that are free-living or symbiotic.
Briefly describe the difference between these types of organisms and give two examples of each. Briefly describe how Rhizobium infects a leguminous root. Give the reaction that nitrogenase catalyzes. Briefly describe the two molecular components of the nitrogenase molecule.
