Photosynthesis and Cellular Respiration Flashcards

Study Notes

Interrelationship of Photosynthesis and Cellular Respiration

Carbon dioxide and water produced by cellular respiration serve as reactants for photosynthesis.
The overall chemical equations for photosynthesis and cellular respiration are reversible, highlighting their interconnected nature.

Photosynthesis and Atmospheric Gases

Photosynthesis removes carbon dioxide from the atmosphere, making it a vital process for regulating atmospheric CO2 levels.
Key reactants in photosynthesis are carbon dioxide and water.

Muscle Cell Energy Production

During intense, short-duration activities like weightlifting, muscle cells may lack sufficient oxygen, leading to fatigue.
In such cases, muscle cells resort to anaerobic respiration, generating limited ATP by converting sugars into alcohol and carbon dioxide.

Role of ATP

ATP functions as the "energy currency" within cells, capturing and transferring energy for various biological processes.
Energy is stored within ATP’s molecular bonds and released when these bonds are broken, enabling cellular work.

Energy Flow between Photosynthesis and Cellular Respiration

Energy captured during photosynthesis is stored in glucose molecules and utilized for ATP production in cellular respiration.
The process of cellular respiration transfers energy from glucose to ATP, which cells use for their functions.

Bacterial Respiration Types

In observations of two bacterial species, Species X produces carbon dioxide and water, indicating aerobic respiration.
Species Y, which produces ethyl alcohol and carbon dioxide, is determined to be anaerobic, reflecting its ability to perform cellular respiration without oxygen.

Differences in Carbon Dioxide Usage

Photosynthesis consumes carbon dioxide, while cellular respiration generates it as a byproduct.
This distinction highlights the cyclical relationship between these two processes.

Relationship Representation in Diagrams

Diagrams illustrating the relationship between photosynthesis and cellular respiration typically label:
- Oxygen produced during photosynthesis (reactant in cellular respiration).
- Carbon dioxide produced during cellular respiration (reactant in photosynthesis).
This cyclical process is essential for maintaining life on Earth, as plants and animals rely on each other's metabolic outputs.
