2. Light-Independent (Calvin Cycle) - does not need light
For each of these organisms, write yes or no as to whether or not they do cellular respiration.

RANDOM: In the classic Christmas movie, How the Grinch Stole Christmas, the Grinch was described using 3 words. What were those words?
Stink!
Stank!
Stunk!
What sugar does a molecule of ATP have in it?
Ribose
How many cycles of the Calvin Cycle does it take to get 1 net G3P?
3 cycles
What are the names of the 3 stages of cellular respiration if oxygen is available?
1. Glycolysis (this stage doesn't need oxygen)
2. Citric Acid Cycle/Kreb's Cycle (needs oxygen)
3. ETC (needs oxygen)
What is decomposition?
What are 2 examples of decomposers?
Decomposition is when either worms, bacteria, or fungi break down dead matter and return it to the soil (carbon/nitrogen).
If an enzyme works best at 100 degrees Farenheit in the human body, what do you think it is good at doing?
Getting rid of harmful viruses/bacteria that cause sicknesses that result in having a fever.
What process in aerobic respiration produces a TON of ATP?
ETC - creates 34 molecules of ATP
What are the names of the 2 energy-containing molecules that take energy from the Light-Dependent reaction to the Light-Independent reaction?
ATP and NADPH
How many total molecules of ATP come from aerobic respiration?
How many total molecules of ATP come from anaerobic respiration?
Aerobic: 36-38 (this one is more energy efficient)
Anaerobic: 2-4
Name 3 stages of the water cycle, and tell me what happens during those stages.
Condensation: water droplets condense in the atmosphere to form clouds
Precipitation: water falls from the sky (rain, snow, sleet, hail)
Runoff: water hits pavement/buildings and collects in bodies of water
Infiltration: water is able to seep into the ground
Evaporation: water droplets are heated up to become a vapor and go back into the atmosphere
Transpiration: water comes out of a plant's stomata and returns to the atmosphere
