What kind of organisms perform photosynthesis? Be Specific.
Autotrophs/Plants/Trees/Algae/Seaweed/Flowers
100
What are the reactants of photosynthesis?
Carbon Dioxide, Water, and Sunlight
100
What are the reactants of cellular respiration?
Oxygen and Glucose Sugar
100
What are the products of cellular respiration?
Water, Carbon Dioxide, ATP Energy
200
What are the products of Photosynthesis?
Oxygen and Glucose Sugar (C6H12O6)
200
True or False: Photosynthesis happens at night.
False. Plants cannot do photosynthesis at night because there is no sunlight. Instead they do cellular respiration!
200
What are the three stages of aerobic cellular respiration?
Glycolysis, Krebs Cycle (Citric acid cycle), and Electron Transport Chain
200
Why do we need to produce ATP in cellular respiration?
In order to gain energy for cellular processes
300
What happens when we break off a phosphate group from ATP? What molecule does it become?
Releases energy and becomes ADP
300
What happens to the glucose made during photosynthesis?
It can be stored, converted into starch or cellulose, or used during cellular respiration to create ATP energy.
300
What is produced during anaerobic (without oxygen) respiration?
Carbon Dioxide gas, some ATP, ethyl alcohol (in yeast/bacteria), lactic acid (in animal cells)
300
What is the relationship between the processes of photosynthesis and cellular respiration?
The products of one process are the reactants of the other process.
400
What wavelength of light is most effect for Photosynthesis according to this graph?
Violet/Blue and Orange/Red
400
What is the formula for photosynthesis?
6CO2+6H2O+light-->C6H12O6+6O2
400
What is the formula for Cellular Respiration?
C6H12O6+6O2-->6H2O+6CO2+36 ATP
400
In order to do cellular respiration we need two things, glucose and oxygen:
Where do we get glucose from?
Where do we get oxygen from?
Glucose comes from food (in animal cells) and photosynthesis (in plants)
Oxygen comes from the air we breathe and was created by plants during photosynthesis
500
What is produced in the light-dependent reactions of Photosynthesis?
What is produced in the Calvin Cycle (light-independent reactions) of Photosynthesis?
Light-Dependent - ATP, NADH, and Oxygen Gas
Light-Independent - Glucose

NO QUESTION HERE (FREE POINTS FOR EVERYONE!)
You are doing an experiment to look at rates of photosynthesis. You fill 4 tubes with bromothymol blue solution and elodea plants. Test tubes 1-2 are placed in the light while Test tubes 3-4 are placed in a dark cabinet. You come back after 24 hours to find that the BTB solution has changed color in test tubes 3-4. What processes are happening in those test tubes that cause it turn yellow? What processes are happening in test tube 1-2 that cause it to not turn yellow?
Test tubes 3-4 are doing cellular respiration because of the lack of sunlight. This process produces CO2 causing the solution to turn yellow.
Test tubes 1-2 are doing photosynthesis which produces O2 and keeps the BTB solution a blue color.

If I place yeast, sugar, and water into a bottle, what process will be taking place? What gas is being produced?
Alcoholic Fermentation is producing Carbon Dioxide Gas (CO2)

What process occurs when we are exercising? Why do we get sore?
Lactic Acid Fermentation (Anaerobic respiration)
We get sore from the build up of lactic acid during this process.
