Bio Ch 6

Front

What is a biochemical pathway?

Back

A series of linked chemical reactions that occur within a cell.

Front

What happens to the hydrogen ions produced during the light reactions of photosynthesis?

Back

They remain inside the thylakoid.

Front

How does an increase in temperature affect the rate of photosynthesis?

Back

It can cause a rapid decline in the photosynthesis rate if it rises above a certain level.

Front

What occurs when a chlorophyll molecule absorbs a photon of light?

Back

Some of its electrons are raised to a higher energy level.

Front

What is PGAL in the context of the Calvin cycle?

Back

A three-carbon molecule produced during the Calvin cycle.

Front

What are the main stages of photosynthesis?

Back

Light reactions and the Calvin cycle.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to convert carbon dioxide and water into glucose.

Front

What is the significance of thylakoids in photosynthesis?

Back

Thylakoids are membrane-bound structures where the light reactions of photosynthesis occur.

Front

What is the primary product of the light reactions of photosynthesis?

Back

ATP and NADPH.

Front

What is the function of the Calvin cycle?

Back

To convert carbon dioxide into glucose using ATP and NADPH produced in the light reactions.
