Bio 8.1 and 2 Flashcard

Front

Where do light-independent reactions occur during photosynthesis?

Back

In the stroma of chloroplasts.

Front

What are light-absorbing colored molecules found in chloroplasts called?

Back

Pigments.

Front

What does the first law of thermodynamics state?

Back

Energy cannot be created or destroyed, only transformed.

Front

Which of these reactions is catabolic?

Back

Cellular respiration.

Front

What are autotrophs that convert light energy into chemical energy called?

Back

Photoautotrophs.

Front

What is the primary function of chlorophyll in photosynthesis?

Back

To absorb light energy.

Front

What is the role of the stroma in photosynthesis?

Back

It is the site of the light-independent reactions (Calvin cycle).

Front

Define photoautotrophs.

Back

Organisms that use light energy to convert carbon dioxide and water into glucose.

Front

What is the difference between catabolic and anabolic reactions?

Back

Catabolic reactions break down molecules to release energy, while anabolic reactions build molecules and require energy.

Front

What is the significance of pigments in photosynthesis?

Back

They capture light energy necessary for the photosynthetic process.
