How is the Calvin cycle dependent on light?

How is the Calvin cycle dependent on light?

The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers (ATP and NADPH) are products of light-dependent reactions.

What are the resources needed for the Calvin cycle?

The Calvin cycle needs outside resources, these resources are produced by the light-dependent reactions. These “costs” of resources include, 3 co2, 9 ATP, and 6 NADPH. Co2 comes from the atmosphere, however, without light-dependent reactions, the Calvin cycle has no way to obtain the required ATP and NADPH.

Where do the light-dependent reactions occur?

Figure 1 The light-dependent reactions harness energy from the sun to produce ATP and NADPH. These energy-carrying molecules travel into the stroma where the Calvin cycle reactions take place.

Where do the Calvin cycle reactions occur in plants?

These energy-carrying molecules travel into the stroma where the Calvin cycle reactions take place. In plants, carbon dioxide (CO 2) enters the chloroplast through the stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions where sugar is synthesized.

What is produced during light dependent reactions?

Figure 8.3 B. 1: Light Reactions: Light-dependent reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where the Calvin cycle takes place.

What happens to ADP and NAD+ in the Calvin cycle?

The molecules of ADP and NAD +, resulting from the reduction reaction, return to the light-dependent reactions to be re-energized. One of the G3P molecules leaves the Calvin cycle to contribute to the formation of the carbohydrate molecule, which is commonly glucose (C 6H 12O 6).
