ATP Photosynthesis Practice Test

Question: 1 / 400

In the process of photosynthesis, ATP is primarily used for?

Transferring electrons

Storing carbs

Driving cellular respiration

Powering the Calvin cycle

In photosynthesis, ATP plays a crucial role in the Calvin cycle, which is the phase of photosynthesis where carbon dioxide is fixed into organic molecules, ultimately leading to the production of glucose. The Calvin cycle requires a significant amount of energy, which is provided by ATP, synthesized during the light-dependent reactions of photosynthesis.

In this process, ATP is utilized to convert carbon compounds into glucose precursors through a series of enzymatic reactions. The energy stored in ATP is essential for driving these reactions forward, allowing plants to create the organic molecules they need for growth and energy storage. Hence, ATP is fundamental in facilitating the transformation of carbon dioxide into carbohydrate molecules in the Calvin cycle.
