Question

what is the calvin cycle? a process in which a plant makes water. calvin running in circles. a process in which a plant uses energy and carbon dioxide to produce glucose. a process in which light energy is converted into adp and nadp+

Explanation:

The Calvin Cycle is part of photosynthesis. Plants use energy (from ATP and NADPH, produced in the light - dependent reactions) and carbon dioxide to produce glucose (a carbohydrate) and regenerate the starting molecule (RuBP).

• The orange option is wrong because plants don't make water in the Calvin Cycle; water is split in the light - dependent reactions.
• The blue option is a joke and not a scientific definition.
• The red option is wrong because light energy is converted to ATP and NADPH in the light - dependent reactions, and in the Calvin Cycle, ATP is converted to ADP and NADPH to NADP⁺ as they provide energy and reducing power for the cycle, but the main purpose of the Calvin Cycle is to fix carbon and make glucose, not just the conversion of light energy (which doesn't even happen in the Calvin Cycle).

Answer:

The correct option is the green one: A process in which a plant uses energy and carbon dioxide to produce glucose.
