If a cell is unable to perform aerobic cellular respiration, what is a likely consequence?
- The cell will switch to photosynthesis.
- The cell will produce energy more efficiently.
- Increased ATP production compared to aerobic respiration.

Study Notes
- Organisms can exist as colonial, meaning they're made of multiple cells living together but capable of independent survival, examples include Volvox, algae, coral, and sponges.
Division of Labor
- Multicellular organisms exhibit a division of labor, where specific cells or tissues specialize in certain functions rather than performing all tasks, for example muscles specializing in movement
Producers vs. Consumers
- Producers create their own energy (e.g., plants, algae).
- Consumers cannot create their own energy (e.g., humans, animals, fungi, most bacteria).
ATP
- ATP is the usable form of energy for cells.
Cellular Respiration
- Cellular respiration happens in both producers and consumers.
- Enzymes are necessary for cellular respiration.
- Cellular respiration stores energy as ATP.
Anaerobic Cellular Respiration
- Anaerobic cellular respiration is less efficient at producing energy than aerobic.
- Anaerobic cellular respiration uses sugar as an energy source.
- Oxygen is not required for anaerobic cellular respiration.
- Anaerobic cellular respiration stores energy as ATP.
Aerobic Cellular Respiration
- In aerobic cellular respiration, the chemical energy of sugar transforms into ATP.
- Carbon dioxide is a byproduct of aerobic cellular respiration.
- Aerobic cellular respiration occurs in mitochondria.
Photosynthesis
- Photosynthesis stores energy within the chemical bonds of sugar molecules.
- Energy from sunlight is used during photosynthesis.
- Photosynthesis happens in producers.
- Enzymes are necessary for photosynthesis.
Chlorophyll
- Chlorophyll is the primary pigment in photosynthesis.
- Chlorophyll is a green pigment.
- Pigments are colored substances that absorb light energy.
Irreducible Complexity
- Irreducible complexity is the concept that some biological systems are so intricate and interdependent that removing a component would render them non-functional, suggesting evidence for Creation.
- Photosynthesis is an example of irreducible complexity.
Mitochondria
- Mitochondria "recharge" ATP molecules.
Chemical Equations
- Photosynthesis: carbon dioxide + water + light energy → sugar + oxygen.
- Cellular respiration (aerobic): Sugar + oxygen → carbon dioxide + water + ATP.
Reactants vs. Products
- Reactants are the substances present at the start of a chemical reaction.
- Products are the substances present at the end of a chemical reaction.
Aerobic Cellular Respiration Steps and Location
- Aerobic cellular respiration starts in the cytoplasm.
- Aerobic cellular respiration primarily occurs in the mitochondria.
Levels of Cellular Organization
- Cellular organization levels, from smallest to largest: Cells → Tissue → Organ → Organ System → Organism.
