- X-linked autosomal disorder of infertility
- Y-linked autosomal disorder of infertility
- Y-linked disorder of male infertility

What is the name of the photosynthetic processes?
What do they use and produce?
Light Dependent (Energy Transduction)
Uses: Light (& H2O)
Produces: ATP, NADPH (& O2)
Light Independent (Carbon Assimilation/Calvin Cycle)
Uses: CO2, ATP & NADPH
Produces: Sugars i.e. CH2O (ADP & NADP+)

Why are the lac genes effectively not transcribed in the presence of glucose and lactose?
Glucose inhibits Adenylyl Cyclase from producing cAMP.
So no CAP-cAMP complex to promote RNA Polymerase binding.

IA: A antigen
IB: B antigen
i : None
