Photosynthesis And Respiration Cellular Energy Flashcards
Photosynthesis
Plants use the energy of sunlight to produce their own food such as glucose
All life depends on a source of ________.
Energy
Plants are able to convert ______ energy to _______energy, which is stored in the bonds of sugars.
Light , chemical
H2O + CO2 + light energy ➡️ O2 + C6H12O6
Overall reaction of photosynthesis
Light is absorbed by pigments in leaves structures called _______
Chloroplasts
Respiration
The cellular process by which energy stored in nutrients is released as ATP
What are the two major pathways by which cells extract energy from nutrients?
Respiration and fermentation
________ involves a series of reactions in which hydrogen electrons are transferred from glucose to oxygen gas, resulting in the formation of water
Respiration
O2 + C6H12O6 ➡️ H2O + CO2 + cellular energy (ATP)
The overall reaction of respiration from glucose
Fermentation
“without air”: Because there is an absence of oxygen gas, fermentation is a type of anaerobic respiration
What are the two common types of fermentation?
Alcohol and lactate (lactic acid)
Acidic solution
Ph is less than seven; turns yellow
Basic solution
PH is greater than seven; it becomes red
Electron acceptor
Chemical entity that excepts electrons transferred to it from another compound
What is the final electron acceptor in respiration?
Oxygen
