Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process used by plants and other autotrophs to capture light energy and convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches.

Front

What organelle is responsible for photosynthesis?

Back

The chloroplast is the organelle responsible for making food (glucose) using sunlight.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment in chloroplasts that absorbs light energy to perform photosynthesis.

Front

What are electron transport chains?

Back

Electron transport chains are a series of electron carrier proteins that shuttle high-energy electrons during ATP-generating reactions.

Front

What molecule supplies chlorophyll with electrons?

Back

Water supplies chlorophyll with electrons during the light-dependent reactions of photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the Calvin Cycle (light-independent reactions).

Front

What is the primary function of the light-dependent reactions?

Back

The primary function of the light-dependent reactions is to convert light energy into chemical energy in the form of ATP and NADPH.

Front

What is produced during the light-dependent reactions?

Back

Oxygen gas, ATP, and NADPH are produced during the light-dependent reactions.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the set of light-independent reactions in photosynthesis that convert carbon dioxide and other compounds into glucose.

Front

What is the significance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for most living organisms.
