Question

Give one point of difference between respiration and photorespiration.?

Answer 1

Dear Student,

◆ Difference between Respiration and Photorespiration -

1. Respiration occurs in animals while photorespiration occurs in plants.
2. Raw materials in respiration are glucose and oxygen while raw materials in photorespiration are CO2 and water.
3. Products in respiration are CO2 and water while products in photorespiration are glucose and oxygen.
4. Respiration occurs in mitochondria while photorespiration occurs in chloroplast.

Thanks dear. Hope this helps you..

Answer 2

The main point of difference is that photorespiration does not involve glycolysis, Krebs cycle and ETS, whereas respiration involves all the process.

Explanation:

• Photorespiration, also known as C2 photosynthesis or glycolate metabolism is a type of respiration which occurs under high light intensities.
• This occurs in the plants where the oxygen is being process in the plant Calvin cycle instead of Carbon dioxide.
• This process is initiated in the chloroplasts and the presence of light is mandatory.
