Photosynthesis

ATP, NADPH₂, Oxygen

The light reaction produces ATP (energy currency), NADPH₂ (reducing power), and oxygen (as a byproduct of water splitting). Glucose is produced in the dark reaction, not the light reaction.

True

This is the correct balanced equation for photosynthesis, showing that carbon dioxide and water are converted to glucose and oxygen in the presence of light and chlorophyll.

Light intensity, Carbon dioxide concentration, Temperature, Water availability

According to Blackman's law of limiting factors, light, CO₂, temperature, and water can all act as limiting factors for photosynthesis. Soil pH indirectly affects plant health but is not a direct limiting factor for photosynthesis.

True

Photorespiration occurs when Rubisco binds with oxygen instead of carbon dioxide, especially under conditions of high temperature, bright light, and low CO₂ concentration. This is a wasteful process for the plant.
