What is Photorespiration c4?
Photorespiration is a wasteful pathway that occurs when the Calvin cycle enzyme rubisco acts on oxygen rather than carbon dioxide. The majority of plants are C 3 \text C_3 C3start text, C, end text, start subscript, 3, end subscript plants, which have no special features to combat photorespiration.
What is photosynthesis formula?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What is the difference between C3 and C4 photosynthesis?
C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.
What is photorespiration and why is it a problem?
In cellular respiration it is a positive term, a process vital to life. But photorespiration is an entirely negative term because it represents a severe loss to the process of using light energy in photosynthetic organisms to fix carbon for subsequent carbohydrate synthesis.
Is photorespiration good or bad?
Photorespiration is either a necessary evil of plant metabolism or it may have some adaptive function that is not apparent. Some have proposed that photorespiration allows plant leaves to use up excess light energy and reduce photooxidative damage when the plant is water-stressed and the stomata are closed.
What is sunlight formula?
Answer: There isn’t a formula for sunlight because what we experience as sunlight is a pure energy released from billions of fusion reactions taking place within the sun. Essentially elements are continuing to undergo high energy reactions which result in the result of light as waves of energy.
How do you read photosynthesis equation?
The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
