interrelationship between respiration and photosynthesis Flashcards
What is photosynthesis
process by which plants can convert light energy to chemical energy
What is the equation for photosynthesis?
What is the equation for respiration?
6CO2 + 6H20 + energy from photons = C6H12O6 + 6o2
C6H12O2 + 602 =6H20 + 6CO2 + ENERGY
What is a photon
a particle of light- has a quantum of energy
what are the two products of photosynthesis
Carbohydrate C6H12O6
6o2
Photosynthesis is an example of carbon fixation. What is carbon fixation
Process of coverting CO2 Into sugar.
what type of reaction is photosynthesis
What type of reaction is respiration
endothermic
Exothermic
What are the benefits of carbon fixation
Regulates the concentration of carbon dioxide in the ocean and atmosphere
Organisms rely on photosynthesis
Why is carbon fixation a reduction reaction
It needs electrons, the addition of electrons = reduction
What are the two types of autotroph
Phototroph- use light energy for autotrophic nutrition
Why are photoautotrophs called “Producers”
they begin the food chain, provide energy for non photosynthetic organisms
what is respiration
oxidisation of carbon carbohydrates and oxygen to release chemical energy
are non photosynthetic organisms or photosynthetic organisms are heterotrophs
Heterotrophiv- non- photosynthetic
what is a heterotroph
obtain energy from digesting complex molecules to smaller molecules for use as a respiratory substrate
cant photosynthesise.
what times of day does photosynthesis take place in comparison to respiration
Photosynthesis- daytime
respiration- all the time
how do photosynthesis and respiration interelate
The products of photosynthesis are the raw materials for respiration. viceversa.
