The population density of a particular insect species was determined to be 15,000 adults per hectare in the summer of 1996, 21,000 adults per hectare in the summer of 1997, and 29,400 adults per hectare in the summer of 1998.

What would you expect the insect population to be in the summer of 2000, assuming no change in λ?

The Calvin–Benson cycle pathway decreases the oxidation state of carbon from the highest value, found in CO2 (+4), to levels found in sugars;  +2 in keto groups — CO—; 0 in secondary alcohols —CHOH,  In view of its notable capacity for lowering the carbon oxidation state, the Calvin–Benson cycle is also aptly named the

There are two distinct forms of rubisco. Form I is found in vascular plants, algae, and cyanobacteria; form II is confined to certain photosynthetic bacteria, Some statements about the Rubisco is given;

a.) A complex form I structure with eight identical large subunits each containing a catalytic site, and eight identical small subunits of uncertain function

b.) The form II rubisco of photosynthetic bacteria is simpler in structure, having two subunits that in many respects resemble the large subunits of the plant enzyme

c.) The plant enzyme has an exceptionally low turnover number; only three molecules of CO2 are fixed per second per molecule of rubisco at 25 o C

d.) Rubisco makes up almost 50% of soluble protein in chloroplasts and is probably one of the most abundant enzymes in the biosphere
