Photorespiration exam Flashcards

A process in plants that occurs under hot conditions when stomata close, leading to the production of carbon dioxide and wasting ATP and NADPH.

Stomata close to prevent dehydration, which also prevents gas exchange.

An enzyme that binds oxygen to RuBP during photorespiration instead of carbon dioxide.

It counteracts the carbon fixation process, wasting ATP and NADPH, and produces carbon dioxide instead of glucose.

Openings in plant leaves that control gas exchange and water loss.

Photosynthesis consumes carbon dioxide to produce glucose, while photorespiration produces carbon dioxide and wastes energy.

A molecule that binds with carbon dioxide during the Calvin cycle or with oxygen during photorespiration.

Hot temperatures to prevent water loss through evaporation.

The Calvin cycle is a process in photosynthesis that fixes carbon dioxide to produce G3P, which can be further utilized to synthesize glucose and other carbohydrates.

Oxygen levels increase inside the plant because it cannot diffuse out.

Energy molecules produced in the light reactions of photosynthesis and wasted during photorespiration.

Carbon dioxide levels decrease because it cannot enter the plant when stomata are closed.

The process of carbon dioxide entering and oxygen leaving the plant through stomata.

Rubisco binds oxygen to RuBP instead of carbon dioxide, leading to photorespiration.

The inner tissue of a leaf where photosynthesis and gas exchange occur.

Water molecules can diffuse out of the plant through evaporation.

The process of converting carbon dioxide into organic compounds during photosynthesis.

To prevent dehydration and water loss through evaporation.

The phase of photosynthesis where light energy is converted into ATP and NADPH.

It leads to photorespiration, wasting energy and producing carbon dioxide.

The loss of water from a plant, which can be prevented by closing stomata.

Photorespiration competes with photosynthesis by using up resources and producing carbon dioxide.

The fluid-filled space inside chloroplasts where the Calvin cycle occurs.

It reduces glucose production by wasting ATP and NADPH and producing carbon dioxide.

The process by which water molecules leave the plant through stomata.

They are wasted, making photosynthesis inefficient.

A gas consumed during photosynthesis and produced during photorespiration.

It highlights plant adaptations for managing gas exchange and water loss in varying environments.
