B4- Aerobic and Anaerobic respiration

Question 1

what is aerobic respiration

Answer 1

RESPIRATION WITH OXYGEN
-most efficient way to transfer energy from glucose
-

Question 2

what is anaerobic respiration?

Answer 2

your body can’t supply oxygen to your muscles, they start doing anaerobic respiration (used in exercise)
-WITHOUT OXYGEN
-doesn’t transfer much energy
because GLUCOSE ISN’T FULLY OXIDISED
-only emergencies

Question 3

what is word equation for anaerobic respiration?

Answer 3

glucose —> lactic acid

Question 4

what is word equation for anaerobic respiration within plants and yeast cells?

Answer 4

glucose —> ethanol + carbon dioxide

Question 5

what is oxygen debt?

Answer 5

amount of extra oxygen the body needs after exercise to react with lactic acid and remove it

Question 6

what does lactic acid cause?

Answer 6

muscle fatigue
aching
muscles stop contracting efficiently

Question 7

what happens when you exercise

Answer 7

muscle contraction- increases
demand for energy increases
increased respiration
heart rate flow increases
blood flow increases
breathing rate increases
