Photosynthesis and Cellular Respiration

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the main difference between photosynthesis and cellular respiration?

Back

Photosynthesis uses carbon dioxide and produces oxygen, while cellular respiration uses oxygen and produces carbon dioxide.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2

Front

What gas do plants release during photosynthesis?

Back

Oxygen

Front

What happens to the rate of photosynthesis if carbon dioxide levels increase?

Back

The rate of photosynthesis increases.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What is ATP and its role in cellular respiration?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, produced during cellular respiration to provide energy for various cellular processes.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

What is the significance of the light-dependent reactions?

Back

The light-dependent reactions convert solar energy into chemical energy (ATP and NADPH) and produce oxygen as a byproduct.
