Answer: cellular respiration reverses the overall photosynthetic reaction, but less efficiently. The useful energy output of respiration is less than the energy input required for photosynthesis.
Explanation:
overall photosynthetic reaction
Light energy + 6CO2 + 6H2O —> C6H12O6 + 6O2
cellular respiration
C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy (as ATP and heat)
Preganglionic fibres originate in the sacral region off the spinal cord.
The carbon cycle is the movement of carbon from cellular respiration and human interference to the atmosphere. Human interference adds an excessive amount of carbon to the atmosphere, resulting in an imbalance. This imbalance means there is less oxygen available to organisms who need it, such as humans and animals. Burning of fossil fuels and deforestation are some contributors into the imbalance of carbon and oxygen in the atmosphere. Hope this helps! :)
