Question

Explain why photosynthesis and respiration in plants are not exactly opposite chemical reaction? Justify ur answer.

Answer 1

Answer:

Difference between photosynthesis and respiration.

1 .during respiration the product of digestion such as glucose react with the oxygen to form co2 water and energy is released.

2. During photosynthesis the green plants prepare glucose from from co2 and water in the presence of sunlight and chlorophyll.

Answer 2

In respiration oxygen helps break down sugars to obtain energy and carbon dioxide is released.

Explanation:

• They are opposites because they are the same chemical reaction but reversed.
• Cellular respiration takes glucose (from nutrient/food) and oxygen (from atmosphere) in order to make CO2 (think about exhaling) and H20 (water).
• In photosynthesis carbon dioxide and water in the presence of sunlight and chlorophyll form oxygen and ATP.
• Photosynthesis converts carbon dioxide and water into oxygen and glucose.
