Cell Theory
Active vs passive transport
Diffusion and Osmosis, Bulk transport (endocytosis and Exocytosis)
Tonicity
Learn all the eukaryotic animal cell organelles (including the membrane and the
cytoplasm, structure and function
 Aerobic Respiration: You should be able to give a thorough accurate and
detailed lecture on this topic including the structure of the mitochondrion, what
the substrates and products are, the details of the 3 parts of this process
(Glycolysis, the Krebs Cycle and Electron Transport Phosphorylation) write out
the formula
1 Pyruvate from
cytoplasm enters
inner mitochondrial
compartment.
NADH
acetyl-CoA
NADH
Krebs
Cycle
NADH
4 As electrons
move through the
transport system,
H+ is pumped to
outer
compartment.
3 NADH and
FADH2 give up
electrons and H+
to electron
transport
systems.
ATP
2 Krebs cycle and
preparatory steps:
NAD+ and FADH2
accept electrons
and hydrogen. ATP
forms. Carbon
dioxide forms.
OUTER COMPARTMENT
ATP
ATP
ATP
5 Oxygen
accepts
electrons,
joins with H+
to form
water.
ADP
+ Pi
INNER COMPARTMENT
6 H+ flows back into inner
compartment, through ATP synthases.
Flow drives ATP formation.
