Photosynthesis and Cellular Respiration Quiz

Study Notes

Photosynthesis and Cellular Respiration

Photosynthesis and cellular respiration are interdependent processes; products of one serve as reactants for the other.
The equations for these processes are inversely related; cellular respiration's equation is the reverse of photosynthesis'.

Cellular Respiration Equation

Represented by the formula: C6H12O6 + 6O2 → 6CO2 + 6H2O.

Photosynthesis Equation

Represented by the formula: 6CO2 + 6H2O → C6H12O6 + 6O2.

Connection Between Photosynthesis and Cellular Respiration

Photosynthesis produces glucose, which is essential for cellular respiration to generate ATP.
The glucose is converted back into carbon dioxide during cellular respiration, which photosynthesis then utilizes.
In photosynthesis, water is divided to release oxygen, while in cellular respiration, oxygen is combined with hydrogen to produce water.

The Carbon Cycle

The carbon cycle is sustained by photosynthesis and cellular respiration processes.
Trees absorb carbon dioxide and emit oxygen, playing a crucial role in maintaining atmospheric balance.
Deforestation negatively impacts the carbon cycle, reducing its efficiency.
Increased combustion of fossil fuels raises carbon dioxide levels in the atmosphere.

Photosynthesis

"Photo" translates to light, while "synthesis" means putting together.
Fotosynthesis enables plants (autotrophs) to produce their own food.
Occurs predominantly in the leaves containing chloroplasts, which have chlorophyll that provides the green pigment.

Cellular Respiration

Cellular respiration is essential for energy production in cells.
This process converts glucose into adenosine triphosphate (ATP), the energy currency of cells.

Aerobic Respiration

Reactants include glucose and oxygen.
Generates a high energy yield of approximately 36-38 ATP.
Byproducts are carbon dioxide (CO2) and water (H2O).

Anaerobic Respiration

Reactants consist of glucose only.
Yields low energy output, around 2 ATP.
Produces byproducts such as lactic acid in animals and ethanol and carbon dioxide in yeast and bacteria.
