B4 Bioenergetics Flashcards
What is the word equation for Photosynthesis?
Water + Carbon dioxide –> Glucose + oxgen
What is the balanced symbol equation for Photosynthesis?
6H2O + 6CO2 –> C6H12O6 + 6O2
what type of reaction is photosynthesis?
endothermic.
How is rate increased in photosynthesis?
Temperature, light intensity, CO2 conc.
What does respiration provide energy for?
Chemical reactions, warmth and movement.
What is the word equation for Aerobic respiration?
glucose + oxygen –> carbon dioxide + water
what is the symbol equation for Aerobic respiration?
C6H12O6 + 6O2 –> 6H2O + 6CO2
What happens to the body during exercise?
heart and breathing rate increase to increase blood flow to supply more glucose and oxygen for muscle contraction.
What is the equation for Anaerobic respiration?
glucose –> lactic acid
When does Anaerobic respiration occur?
during intense exercise; oxygen debt.
what is the equation for Anaerobic respiration in plants?
Glucose –> ethanol + carbon dioxide (fermentation)
What is metabolism?
The sum of all chemical reactions in a cell/organism.
