Photosynthesis vs. 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. It occurs in both plants and animals.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to store and transfer energy for various cellular processes.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that occur in the stroma of chloroplasts during photosynthesis, where carbon dioxide is fixed into glucose.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a raw material used in photosynthesis, where it is converted into glucose during the Calvin Cycle.

Front

What is the waste product of photosynthesis?

Back

Oxygen is the waste product of photosynthesis, released into the atmosphere as a byproduct of converting carbon dioxide and water into glucose.

Front

What organisms perform photosynthesis?

Back

Photosynthesis is primarily performed by green plants, algae, and some bacteria.

Front

What organisms perform cellular respiration?

Back

Cellular respiration occurs in almost all living organisms, including plants, animals, fungi, and many microorganisms.

Front

How are photosynthesis and cellular respiration related?

Back

Photosynthesis and cellular respiration are interconnected processes; photosynthesis converts solar energy into chemical energy (glucose), while cellular respiration converts that chemical energy into usable energy (ATP).

Front

What is the main difference between photosynthesis and cellular respiration?

Back

The main difference is that photosynthesis uses carbon dioxide and water to produce glucose and oxygen, while cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
