Front

What is ATP and its role in cellular energy?

Back

ATP (Adenosine Triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes by releasing a phosphate group.

Front

What happens to ATP during energy release?

Back

During energy release, ATP loses a phosphate group, converting into ADP (Adenosine Diphosphate) and releasing energy.

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.

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

How are photosynthesis and cellular respiration related?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce ATP, carbon dioxide, and water, forming a cycle.

Front

What is the significance of chlorophyll 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 is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a key reactant in photosynthesis, used by plants to produce glucose.

Front

What is the effect of light intensity on photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis up to a certain point, after which other factors may limit the process.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis, providing electrons and protons needed for the conversion of light energy into chemical energy.

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as converting solar energy into chemical energy during photosynthesis.
