Select Cumulative Review -- IB Year I
Semester I – December 2009
“Select” means key concepts are being emphasized. In other words, this review is not all
inclusive; rather its intent is to give you specific material to focus on. This final exam

2) Draw the basic structures of the following: amino acid, glucose, ribose, fatty
acid, and glycerol.
2.3 Enzymes
3) Define the terms enzyme and substrate.
4) How does the ‘induced fit’ model help explain enzyme substrate specificity?

5) Explain the light-dependent reaction. Including Photophosphorylation in
terms of chemiosmosis (ETC to make ATP and NADPH).
6) Explain the light-independent reaction. Include the roles of ribulose
bisphosphate (RuBP) carboxylase, reduction of glycerate 3-phosphate (OP) to
triose phosphate (TP), NADPH + H, ATP, regeneration of RuBP and
