Unit 2 Cell Structure and Function Review #2

Front

What effect does increasing CO₂ concentration in water have on photosynthesis?

Back

The higher the CO₂, the greater the rate of photosynthesis.

Front

Where are proteins destined for the membrane synthesized?

Back

On a ribosome attached to the rough endoplasmic reticulum.

Front

How does light intensity affect the rate of photosynthesis?

Back

Increases the rate, up to a point.

Front

What product of the light-dependent reactions is used in the light-independent reactions to produce glucose?

Back

NADPH.

Front

What conclusion can be drawn from a graph showing CO₂ concentration and photosynthesis rate?

Back

Beyond 500 umol/l CO₂, the rate of photosynthesis does not increase.

Front

Define photosynthesis.

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to drive the photosynthesis process.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What is the primary function of the rough endoplasmic reticulum?

Back

To synthesize and process proteins that are to be secreted or sent to the cell membrane.

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH provides the reducing power for the conversion of carbon dioxide into glucose during the Calvin cycle.
