1982:
Describe the similarities and differences between the biochemical pathways of aerobic respiration and photosynthesis in eukaryotic cells. Include in your discussion the major reactions, the end products, and energy transfers.
1971:
The process of photosynthesis consists of two phases, the light reactions and the dark reactions.
Discuss each of these groups of reactions and their interrelationships.
1974:
The overall equation for aerobic respiration is usually written as the reverse of the overall equation for photosynthesis. What features of the biochemical pathways involved in the processes are the reverse of one another and what features are not?
1993:
Membranes are important
structural
features of cells.
(b) Describe the
role of
membranes in the synthesis of ATP in either cellular
1990:
The results below are
measurements of
cumulative oxygen consumption by germinating and dry seeds. Gas volume
measurements were corrected for changes in temperature and pressure.

a. Using the graph
paper provided,
plot the results for the germinating seeds at 22ºC and 0º C.
b. Calculate the rate
of oxygen
consumption for the germinating seeds at 22º C, using the time
interval
between 10 and 20 minutes.
c. Account for the
differences in
oxygen consumption observed between:
1) germinating seeds at 22º C and at 10ºC;
2) germinating seeds and dry seeds.
