To make my my question simpler, is ATP formed during photosynthesis or cellular respiration?

If I can figure out that little fact I'll be able to do the rest of my worksheet...

To determine whether ATP is formed during photosynthesis or cellular respiration, we can break down the processes involved in each of them.

1. Photosynthesis: Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, water, and carbon dioxide into glucose (a form of sugar) and oxygen. It occurs in the chloroplasts of plant cells. There are two stages of photosynthesis:

a. Light-dependent reactions: In this stage, light energy is captured by chlorophyll and other pigments in the chloroplasts. The captured energy is used to split water molecules, releasing oxygen as a byproduct. This stage generates energy in the form of ATP through a process called photophosphorylation.

b. Light-independent reactions (Calvin cycle): In this stage, the ATP and energy carrier molecules produced in the previous stage are used to synthesize glucose from carbon dioxide. However, the direct formation of ATP does not occur in the Calvin cycle.

2. Cellular respiration: Cellular respiration is the process by which cells break down glucose and other organic molecules to release energy. It occurs in the mitochondria of cells. There are three stages of cellular respiration:

a. Glycolysis: In this stage, glucose molecules are broken down into two molecules of pyruvate, releasing a small amount of ATP.

b. Citric acid cycle (Krebs cycle): In this stage, the pyruvate is further broken down, releasing more ATP and other energy carrier molecules.

c. Electron transport chain: In this final stage, the energy carrier molecules produced in the previous stages are used to generate a large number of ATP molecules through a process called oxidative phosphorylation.

Based on this information, we can conclude that the direct formation of ATP occurs during cellular respiration in the stages of glycolysis, the citric acid cycle, and the electron transport chain. In photosynthesis, ATP is produced during the light-dependent reactions but not in the light-independent reactions (Calvin cycle).
