Basics
What are the reactants of cellular respiration?
Glucose and oxygen
Where in the cell does cellular respiration take place?
Mitochondria
Producers and consumers convert sugar to ATP during which process?
Cellular respiration
What are the two types of fermentation?
Lactic acid and alcoholic fermentation
During fermentation of soda, which gas is produced?
Carbon dioxide
What are the products of cellular respiration?
Carbon dioxide, water, and ATP
Photosynthesis is to chloroplasts as cellular respiration is to what?
Mitochondria
What is the relationship between cellular respiration and photosynthesis?
They are opposite processes (products of one are reactants of the other)
Is fermentation aerobic or anaerobic?
Anaerobic
Which organisms carry out anaerobic respiration?
Bacteria and yeast
What is the correct balanced equation for cellular respiration?
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Producers capture the sun’s energy in their what?
Chloroplasts
If there is more photosynthesis, what happens to CO₂?
CO₂ decreases
Fermentation continues the breakdown of glucose during which process?
Glycolysis
In the algae bead lab, what was the independent variable?
Light (light vs dark)
Which type of cellular respiration produces the most energy?
Aerobic respiration
The sun’s energy is captured and converted in what process?
Photosynthesis
If algae beads are exposed to more light, what happens?
More photosynthesis occurs
Respiration with plenty of oxygen is which type?
Aerobic respiration
What was the dependent variable? (Algae Bead Lab)
Color change / CO₂ levels
What is the correct sequence of events in cellular respiration?
Glycolysis → Krebs Cycle → Electron Transport Chain
The sun’s energy is stored in the chemical bonds of what molecule?
Glucose
If algae beads are exposed to no light, what happens?
Only cellular respiration occurs (CO₂ increases)
What is the main difference in end products between lactic acid fermentation and alcoholic fermentation?
Lactic acid fermentation produces lactic acid, while alcoholic fermentation produces ethanol and carbon dioxide
In the algae bead lab, why did the indicator change color in the light vs dark conditions?
Light increased photosynthesis (less CO₂), while dark increased respiration (more CO₂), causing color change
