AP.Bio Unit 3 Review Cellular Energetics

Front

What is the relationship between photosynthesis and cellular respiration?

Back

The products of photosynthesis (glucose and oxygen) are the reactants needed for cellular respiration, and vice versa.

Front

What are cyanobacteria and how do they perform photosynthesis?

Back

Cyanobacteria are photosynthetic bacteria that perform photosynthesis similarly to algae and plants, but they do not have chloroplasts.

Front

What is the primary molecule that stores long-term energy in cells?

Back

Glucose.

Front

What molecule is used for short-term energy to perform work in cells?

Back

ATP (adenosine triphosphate).

Front

How do CAM plants minimize water loss during the day?

Back

CAM plants keep their stomata closed during the day and fix CO2 into organic acids at night.

Front

In which part of the plant cell do the light-independent reactions of photosynthesis occur?

Back

In the stroma.

Front

What is the main purpose of photosynthesis?

Back

To convert light energy into chemical energy stored in glucose.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and light-independent reactions (Calvin cycle).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, to drive the photosynthetic process.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
