Basic Concepts of Photorespiration
What is photorespiration?
A process in plants where oxygen is consumed and carbon dioxide is released
why does shorter wave lenghts contain more energy?
They correpond to a higher wave frequency.
when water is oxidized what does it release?
It releases electrons, hydrogen ions and oxygen
What powers the Calvin cycle reaction?
Powered by ATP and N A D P H
what is the pigment complex
chlorophyll and carotenoids
Which gas is consumed during photorespiration?
Oxygen (O₂).
How does Cellular respiration break down food?
A glucose molecule is broken down into carbon dioxide and water.
solar energy
Where does the calvin cycle occur?
The stroma
___ for gatheing solar energy
Antenna
Photorespiration occurs when the enzyme Rubisco reacts with which molecule instead of carbon dioxide?
Oxygen (O₂).
What is the chemical equation for cellular respiration?
C6H12O6
Wheres does the cellular respiration take place?
In the Mitochrondria
The calvin cycle reduces CO2 to
GP3
what is the rule of ATP synthesis in the light reaction
ATP synthesis produces atp from ADP and in organic phosphate during chemiosmosis
What is the primary problem caused by photorespiration in plants?
It reduces the efficiency of photosynthesis by diverting energy away from the production of sugars.
which of the following is a property of the crassulean acid metabolism (cam) adaption?
CAM plants experience CO2 uptake at night
What is ATP and NADPH used for?
To reduce CO2 to a carbohydrate
How many PGA's does 1 carbon dioxide make?
2
In C4 plants, how does the structure of the leaf help reduce photorespiration?
C4 plants spatially separate the initial fixation of CO₂ in mesophyll cells and the Calvin cycle in bundle sheath cells, concentrating CO₂ around Rubisco.
During photorespiration, which compound does Rubisco initially fix, leading to a series of reactions?
Ribulose bisphosphate (RuBP).
What color do plants not absorb?
Green
What is the end product of the photosynthetic process?
CH20 or Glucose C6 H12 06
What is the second step of the Calvin cycle?
Reduction
What is the role of mitochondria in the photorespiratory cycle?
hey help convert glycine to serine, releasing carbon dioxide as a byproduct.
