Which of the following is true about the photosynthesis processa)Light...
The true statements about the photosynthesis process are:
1. Light reaction of photosynthesis occurs only during the day:
This statement is incorrect. The light reaction of photosynthesis occurs in the presence of light, but it can occur during the day or night. During the light reaction, light energy is absorbed by chlorophyll in the chloroplasts of plant cells. This energy is used to convert water and carbon dioxide into oxygen, ATP (adenosine triphosphate), and NADPH (nicotinamide adenine dinucleotide phosphate).
2. ATP is synthesized during the daytime:
This statement is correct. ATP is synthesized during the light reaction of photosynthesis, which primarily occurs during the daytime when light is available. ATP is an energy-rich molecule that is used by plants and other organisms for various cellular processes and reactions.
3. Dark reaction only occurs at night:
This statement is incorrect. The dark reaction, also known as the Calvin cycle or the light-independent reaction, does not necessarily occur only at night. It can occur during the day as well. The dark reaction utilizes ATP and NADPH produced during the light reaction to convert carbon dioxide into glucose and other organic molecules.
4. Dark reaction does not require light:
This statement is correct. The dark reaction, as the name suggests, does not directly require light energy. It can occur in the absence of light as long as ATP and NADPH produced during the light reaction are available. However, the dark reaction is dependent on the products of the light reaction, which are generated in the presence of light.
In summary, the correct statements about the photosynthesis process are that ATP is synthesized during the daytime, and the dark reaction does not require light but relies on the products of the light reaction.
