Students learn about Metabolic pathways consisting of chains and cycles of enzyme-catalyzed reactions and the following concepts in this module.

Concepts:

  • Enzymes lower the activation energy of the chemical reactions that they catalyse.
  • Enzyme inhibitors can be competitive or non-competitive.
  • Metabolic pathways can be controlled by end-product inhibition.
  • Cell respiration involves the oxidation and reduction of electron carriers.
  • Phosphorylation of molecules makes them less stable.
  • In glycolysis, glucose is converted to pyruvate in the cytoplasm.
  • Glycolysis gives a small net gain of ATP without the use of oxygen.
  • In aerobic cell respiration pyruvate is decarboxylated and oxidized, and converted into acetyl compound and attached to coenzyme A to form acetyl coenzyme A in the link reaction.
  • In the Krebs cycle, the oxidation of acetyl groups is coupled to the reduction of hydrogen carriers, liberating carbon dioxide.

Prior Learning: Students are expected to basic life processes and mechanisms of autotrophic nutrition, cell metabolism and catabolic and anabolic processes.

Students learn the following concepts in this module:

  • Transpiration is the inevitable consequence of gas exchange in the leaf.
  • Plants transport water from the roots to the leaves to replace losses from transpiration.
  • The cohesive property of water and the structure of the xylem vessels allow transport under tension.
  • Plants transport organic compounds from sources to sinks.
  • Incompressibility of water allows transport along hydrostatic pressure gradients.
  • Active transport is used to load organic compounds into phloem sieve tubes at the source.
  • High concentrations of solutes in the phloem at the source lead to water uptake by osmosis.
  • Undifferentiated cells in the meristems of plants allow indeterminate growth.
  • Mitosis and cell division in the shoot apex provide cells needed for extension of the stem and development of leaves.

Students learn the following concepts in this module:

  • Chromosomes replicate in interphase before meiosis.
  • Crossing over is the exchange of DNA material between non-sister homologous chromatids.
  • Crossing over produces new combinations of alleles on the chromosomes of the haploid cells.
  • Chiasmata formation between non-sister chromatids can result in an exchange of alleles.
  • Homologous chromosomes separate in meiosis I
  • Sister chromatids separate in meiosis II
  • Independent assortment of genes is due to the random orientation of pairs of homologous chromosomes in meiosis I
  • Gene loci are said to be linked if on the same chromosome.
  • Unlinked genes segregate independently as a result of meiosis
  • Variation can be discrete or continuous
