Write a balanced equation showing the conversion of glucose and oxygen to carbon dioxide and water:
(a) Indicate in your equation which molecule becomes reduced?
(b) Indicate in your equation which molecule becomes oxidized?
(c) What happens to the energy that is released in this redox reaction?

In this experiment, you will be monitoring changes in CO2 concentration due to
aerobic respiration and photosynthesis of each test organism. Which of the
following results would be expected from the conditions described?
Remember this is a closed system (the CO2 cannot escape), and we are monitoring
changes in CO2 concentration over a 3 minute period.
A) An animal will produce a higher increase in CO2 when exposed to the light
than when kept in the dark.
B) A plant will cause an overall higher increase in C02 concentration when
exposed to light versus an plant kept in the dark.
C) A plant will cause an overall higher increase of CO2 concentration when kept
in the dark versus a plant exposed to light.
D) An animal will show a decrease in CO2 while kept in the dark and an increase
in CO2 while in the light.
