bioenergetics Flashcards
What is respiration?
the process by which energy is released from glucose.
Define photosynthesis.
the process by which plants make glucose using carbon dioxide, water and sunlight.
Define limiting factor.
A factor that is slowing down the rate of photosynthesis when it is not present.
What is aerobic respiration?
respiration where oxygen is used to release lots of energy.
What is anaerobic respiration?
respiration where oxygen is not used and only a small amount of energy is released.
What is fermentation?
anaerobic respiration in yeast
Define oxygen debt.
the amount of extra oxygen the body needs after exercise to react with the built-up lactic acid and remove it from the cells.
What is metabolism?
all of the chemical reactions in a cells or body.
What is the number equation for photosynthesis?
6CO^2+6H2O->C6H12O6+6O2
Word equation for aerobic respiration.
glucose + oxygen → carbon dioxide + water
Balanced symbol equation for aerobic respiration.
C6H12O6 + 6O2 → 6CO2 + 6H2O
Word equation for anaerobic respiration in muscles.
glucose ⟶ lactic acid
Word equation for anaerobic respiration in plant and yeast cells.
Glucose →ethanol + carbon dioxide + energy
Balanced symbol for anaerobic respiration in plant and yeast cells.
C6H12O6 ⟶ 2C2H5OH + 2CO2 + 2ATP.
What is anaerobic respiration in yeast cells called?
Fermentation.
