A flask containing photosynthetic green algae and a control flask containing water with no algae are both placed under a bank of lights, which are set to cycle between 12 hours of light and 12 hours of dark. The dissolved oxygen concentrations in both flasks are monitored. Predict what the relative dissolved oxygen concentrations will be in the flask with algae compared to the control flask.
A) The dissolved oxygen in the flask with algae will always be higher.
B) The dissolved oxygen in the flask with algae will always be lower.
C) The dissolved oxygen in the flask with algae will be higher in the light, but the same in the dark.
D) The dissolved oxygen in the flask with algae will be higher in the light, but lower in the dark.
E) The dissolved oxygen in the flask with algae will not be different from the control flask at any time.
Ans: D) The dissolved oxygen in the flask with algae will be higher in the light, but lower in the dark.

Fructose and galactose both have six carbon atoms, twelve hydrogen atoms and six oxygen atoms, just like glucose. A friend of yours says: "Since those sugars have the same number of atoms, they should have the same name." You answer: "While they do have the same number and type of atoms,
A. they are all polysaccharides and have slightly different functions within organisms and therefore have different names." B. they are named differently because of their quaternary structures, which is very important in carbohydrates, especially glucose." C. they are named differently because when heated above their optimal temperature they become denatured and will not react with their substrates." D. they are named differently because they are involved in different DNA nucleotide formation." E. they are named differently because they are alternate forms of the monosaccharide, glucose."
