Respiration Flashcards
(17 cards)
Define Respiration?
the process of transferring energy from glucose, which happens constantly in every living cell.
why is the energy transferred by respiration used to make ATP?
Because the energy transferred by respiration cant be used directly by cells.
ATP stores the energy needed for many cell processes, when a cell needs energy, ATP molecules are broken down and energy is released.
Respiration also transfers SOME energy by?
heat
Describe an Experiment to show Respiration transfers some energy by heat?
When would you use Aerobic Respiration?
when there is plenty of Oxygen available
What is the most efficent way to transfer energy from glucose?
Aerobic respiration as it produces loads of ATP (32 molecules per molecule of glucose)
what kind of respiration would you use most of the time?
Aerobic.
what is the word equation for Aerobic respiration?
Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP)
what is the chemical equation for Aerobic respiration?
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP)
When would one use Anaerobic respiration?
During vigorous exercise, your body can’t supply enough oxygen to your muscles for Aerobic respiration, your muscles start to respire anaerobically as well
how much ATP is created per glucose molecule (anaerobic respiration)
2
What happens during anaerobic respiration in muscles, and why can it cause cramps?
In anaerobic respiration, the glucose is only partially broken down, and lactic acid is also produced, the lactic acid builds up in the muscles and gets painful leading to a cramp
what is the word equation for Anaerobic respiration?
Glucose → Lactic acid (+ a small amount of energy)
what is the word equation for anaerobic respiration in plants?
Glucose → Ethanol + Carbon dioxide (+ a small amount of energy)
What do plants produce during anaerobic respiration instead of lactic acid?
plants respire without oxygen too, but they produce ethanol and carbon dioxide instead of lactic acid
how can Carbon Dioxide production to used to investigate respiration
