UNIT 2
MODULE 1: BIOENERGETICS AND CONSERVATION (cont’d)

SPECIFIC OBJECTIVES EXPLANATORY NOTES SUGGESTED PRACTICAL
ACTIVITIES

Cellular Respiration and ATP Synthesis (cont’d)

Students should be able to:

2.5. explain the process of Including the roles of
oxidative phosphorylation hydrogen and electron
with reference to the carriers; the proton
electron transport chain; gradient, the synthesis of
and, ATP using ATP synthase and
the role of oxygen. No
details of the carriers are
required. A summary of ATP
production should be
known.

2.6. compare the fate of Fermentation allows for the
pyruvate in the absence of regeneration of NAD so that
oxygen in animals and glycolysis can continue in
yeast. the absence of oxygen.
Include the concept of
oxygen debt in mammals;
and note that lactate can be
converted back (oxidised) to
pyruvate when oxygen is
again available. Include
commercial uses of yeast.

3. Energy Flow and Nutrient Cycling

Students should be able to:

3.1. discuss the efficiency of Revision of the terms:
energy transfer between ecosystem, habitat,
trophic levels; ecological niche, food chains
and food webs. Emphasise
the advantages of the food
web.

3.2. discuss the concept of Including the limitations of Construct pyramids of
biological pyramids; the pyramids of numbers, energy using quantitative
biomass and energy. data.
