In addition to alcohol, alcoholic fermentation produces what as a byproduct
carbon dioxide
What percent of the Earth's surface is made up of oceans?
What is 71%
Name one thing that happens during the light dependent phase of photosynthesis.
Water molecules are split, forming oxygen and free electrons.
ATP synthase makes ATP from ADP
Energized electrons pass through the electron transport chain.
The enzyme that bonds carbon dioxide molecules into a 3-carbon chain
RuBisCO
During glycolysis, glucose produced by photosynthesis is broken down into what
pyruvate
Aerobic processes, such as most cellular respiration, require what
oxygen
Which of the following does not affect the rate of photosynthesis? Availability of water, oxygen, carbon dioxide, or the temperature?

electrons
6 carbon sugar that is a product of this phase of photosynthesis
glucose
Although some ATP is produced during the Krebs cycle, the primary purpose of the cycle is to produce what for the electron transport chain
NADH and electrons
In the absence of oxygen, some organisms can use what to obtain energy
fermentation
How are CAM plants different from C3 plants?
CAM plants open their stomata at night.
CAM plants are adapted to hot, dry climates.
CAM plants produce compounds other than G3P to make glucose.
Oxygen
During this phase, NADPH is converted to what?
NADP+ and hydrogen ions
The chemical that shuttle electrons in the electron transport chain
