Photosynthesis & Cellular Respiration

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

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 ATP?

Back

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

Front

Where does photosynthesis occur in plants?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to convert biochemical energy from nutrients into ATP, and then release waste products.

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 chemical equation for cellular respiration?

Back

The chemical equation for cellular respiration is C6H12O6 + 6 O2 -> 6 CO2 + 6 H2O + ATP.

Front

What role do chlorophyll play in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis, such as plants and some bacteria.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy, such as animals and fungi.
