SC.912.L.18.9 Cellular Energy: Interrelatedness

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 the mitochondria of cells.

Front

How do photosynthesis and cellular respiration relate to energy?

Back

Photosynthesis captures energy from sunlight to produce glucose, while cellular respiration uses that glucose to release energy for cellular activities.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (sugar) and oxygen.

Front

What are the main reactants of cellular respiration?

Back

The main reactants of cellular respiration are glucose and oxygen.

Front

What is the significance of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a key reactant in photosynthesis; it is absorbed from the atmosphere and used to produce glucose.

Front

What is the significance of oxygen in cellular respiration?

Back

Oxygen is a key reactant in cellular respiration; it is used to help break down glucose to release energy.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide during photosynthesis and release oxygen, while during cellular respiration, they take in oxygen and release carbon dioxide, thus playing a crucial role in the carbon cycle.

Front

What is ATP and its role in cellular processes?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes, including muscle contraction, nerve impulse propagation, and biosynthesis.
