respiration- key terms

Question 1

Define respiration

Answer 1

Chemical reactions that break down nutrient molecules in living cells to release energy.

Question 2

Define aerobic respiration

Answer 2

chemical reactions in cells that use oxygen to break down nutrient molecules to release energy

Question 3

Define anaerobic respiration

Answer 3

chemical reactions in cells break down nutrient molecules to release energy without using oxygen.

Question 4

Define latic acid

Answer 4

Builds up in muscles and blood during vigorous exercise
The heart, liver and kidneys need extra oxygen to do this, which causes you to continue breathing heavily after exercise.
The extra oxygen is called the oxygen debt.

Question 5

Define how oxyen debt is removed

Answer 5

continuation of fast heart rate to transport lactic acid in the blood from the muscles to the liver
continuation of deeper and faster breathing to supply oxygen for aerobic respiration of lactic acid
aerobic respiration of lactic acid in the liver
