Photosynthesis and Cellular Respiration Review

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 the primary purpose of cellular respiration?

Back

The primary purpose of cellular respiration is to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food from inorganic substances, typically through photosynthesis or chemosynthesis.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.

Front

What role does ATP play in cellular processes?

Back

ATP (adenosine triphosphate) serves as the primary energy carrier in cells, providing energy for various biochemical reactions.

Front

How does an increase in carbon dioxide affect photosynthesis?

Back

An increase in carbon dioxide typically increases the rate of photosynthesis, as it is one of the key reactants in the process.

Front

What is the relationship between photosynthesis and cellular respiration?

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.

Front

What is the significance of BTB in photosynthesis experiments?

Back

BTB (bromothymol blue) is a pH indicator used to measure the amount of carbon dioxide in a solution, indicating photosynthetic activity.

Front

What happens to the color of BTB in the presence of carbon dioxide?

Back

In the presence of carbon dioxide, BTB turns yellow, indicating an acidic environment due to the formation of carbonic acid.

Front

What is the effect of light on photosynthesis?

Back

Light is essential for photosynthesis; it provides the energy needed to convert carbon dioxide and water into glucose.
