F24 Unit 2 Test Review

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 break down glucose and other organic molecules to produce ATP (adenosine triphosphate), which is used as energy by the cell.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce ATP, while cellular respiration releases carbon dioxide and water, which are used in photosynthesis.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells. It stores and provides energy for many cellular processes.

Front

Why does ATP have more potential chemical energy than ADP?

Back

ATP has three phosphate groups, and the bond between the second and third phosphate is high-energy. When ATP is converted to ADP (adenosine diphosphate), it releases energy.

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, which is essential for photosynthesis.

Front

How does temperature affect the rate of photosynthesis?

Back

The rate of photosynthesis generally increases with temperature up to a certain point, after which it may decrease due to enzyme denaturation.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere, which can affect photosynthesis and respiration.
