what event during photo synthesis.
which one is true.
production of co2
increase of cellurar atp
release of o2
break carbohydrate.
During photosynthesis, several events occur in chloroplasts within plant cells. Out of the given options, the following events are true:
1. Production of CO2: This statement is not true. In photosynthesis, plants capture and utilize carbon dioxide (CO2) from the atmosphere, converting it into glucose.
2. Increase of cellular ATP: This statement is true. ATP (adenosine triphosphate) is a high-energy molecule that serves as the primary energy currency of cells. During photosynthesis, ATP is produced through the light-dependent reactions, where energy from sunlight is absorbed and used to generate ATP.
3. Release of O2: This statement is true. One of the primary functions of photosynthesis is to convert light energy into chemical energy, and in the process, oxygen (O2) is released as a byproduct. This is known as oxygenic photosynthesis.
4. Breakdown of carbohydrates: This statement is not true. In photosynthesis, carbohydrates are synthesized, not broken down. In the Calvin cycle (light-independent reactions), ATP and NADPH (another high-energy molecule) produced in the light-dependent reactions are used to convert carbon dioxide into glucose, a carbohydrate.
To summarize, the true events during photosynthesis are the increase of cellular ATP and the release of oxygen (O2).
